Indian rhinoceros

The Indian rhinoceros (Rhinoceros unicornis), also known as the greater one-horned rhinoceros, great Indian rhinoceros, or Indian rhino for short, is a rhinoceros species native to the Indian subcontinent. It is the second largest extant species of rhinoceros, with adult males weighing 2.07–2.2 tonnes and adult females 1.6 tonnes. The skin is thick and is grey-brown in colour with pinkish skin folds. They have a single horn on their snout that grows to a maximum of 57.2 cm (22.5 in). Their upper legs and shoulders are covered in wart-like bumps. They are nearly hairless, aside from the eyelashes, ear fringes and tail brush.

Indian rhinoceros historical range

The Indian rhinoceros is a largely solitary animal, and they only associate in the breeding season and when rearing calves. They are grazers, and their diet is mainly grass, but may also include twigs, leaves, branches, shrubs, flowers, fruits, and aquatic plants. Females give birth to a single calf after a gestation of 15.7 months; the birth interval is 34 to 51 months. Captive individuals can live up to 47 years. They are susceptible to diseases such as anthrax, and those caused by parasites such as leechesticks, and nematodes.

It is listed as Vulnerable on the IUCN Red List, as populations are fragmented and restricted to less than 20,000 km2 (7,700 sq mi). As of August 2018, the global population was estimated to comprise 3,588 individuals. Indian rhinos once ranged throughout the entire stretch of the Indo-Gangetic Plain, but excessive hunting and agricultural development reduced its range drastically to 11 sites in northern India and southern Nepal. In the early 1990s, between 1,870 and 1,895 Indian rhinos were estimated to have been alive. Since then, numbers have increased due to conservation measures taken by the government. However, poaching remains a continuous threat.

Taxonomy edit

Rhinoceros unicornis was the scientific name used by Carl Linnaeus in 1758 who described a rhinoceros with one horn. As type locality, he indicated Africa and India. He described two species in India, the other being Rhinoceros bicornis, and stated that the Indian species had two horns, while the African species had only one.[2]

The Indian rhinoceros is a single species. Several specimens were described since the end of the 18th century under different scientific names, which are all considered synonyms of Rhinoceros unicornis today:[3]

  • R. indicus by Cuvier, 1817
  • R. asiaticus by Blumenbach, 1830
  • R. stenocephalus by Gray, 1867
  • R. jamrachi by Sclater, 1876
  • R. bengalensis by Kourist, 1970[4]

Etymology edit

The generic name rhinoceros is derived through Latin from the Ancient Greek: ῥινόκερως, which is composed of ῥινο- (rhino-, "of the nose") and κέρας (keras, "horn") with a horn on the nose.[5] The name has been in use since the 14th century.[6][7] The Latin word ūnicornis means "one-horned".[8]

Evolution edit

Ancestral rhinoceroses first diverged from other perissodactyls in the Early Eocene. Mitochondrial DNA comparison suggests the ancestors of modern rhinos split from the ancestors of Equidae around 50 million years ago.[9] The extant family, the Rhinocerotidae, first appeared in the Late Eocene in Eurasia, and the ancestors of the extant rhino species dispersed from Asia beginning in the Miocene.[10]

Fossils of R. unicornis appear in the Middle Pleistocene. In the Pleistocene, the genus Rhinoceros ranged throughout South and Southeast Asia, with specimens located on Sri Lanka. Into the Holocene, some rhinoceros lived as far west as Gujarat and Pakistan until as recently as 3,200 years ago.[11]

The Indian and Javan rhinoceroses, the only members of the genus Rhinoceros, first appear in the fossil record in Asia during the Early Pleistocene. The Indian rhinoceros is known from Early Pleistocene localities in Java, South China, India and Pakistan.[12] Molecular estimates suggest the species may have diverged much earlier, around 11.7 million years ago.[9][13] Although belonging to the type genus, the Indian and Javan rhinoceroses are not believed to be closely related to other rhino species. Different studies have hypothesised that they may be closely related to the extinct Gaindatherium or Punjabitherium. A detailed cladistic analysis of the Rhinocerotidae placed Rhinoceros and the extinct Punjabitherium in a clade with Dicerorhinus, the Sumatran rhinoceros. Other studies have suggested the Sumatran rhinoceros is more closely related to the two African species.[14] The Sumatran rhino may have diverged from the other Asian rhinos as long ago as 15 million years.[10][15]

Characteristics edit

The skull of an Indian rhinoceros

Indian rhinos have a thick grey-brown skin with pinkish skin folds and one horn on their snout. Their upper legs and shoulders are covered in wart-like bumps. They have very little body hair, aside from eyelashes, ear fringes and tail brush. Bulls have huge neck folds. The skull is heavy with a basal length above 60 cm (24 in) and an occiput above 19 cm (7.5 in). The nasal horn is slightly back-curved with a base of about 18.5 cm (7.3 in) by 12 cm (4.7 in) that rapidly narrows until a smooth, even stem part begins about 55 mm (2.2 in) above base. In captive animals, the horn is frequently worn down to a thick knob.[11]

The Indian rhino's single horn is present in both bulls and cows, but not on newborn calves. The horn is pure keratin, like human fingernails, and starts to show after about six years. In most adults, the horn reaches a length of about 25 cm (9.8 in), but has been recorded up to 57.2 cm (22.5 in) in length and 3.051 kg (6.73 lb) in weight.[15][11]

Among terrestrial land mammals native to Asia, Indian rhinos are second in size only to the Asian elephant.[17] They are also the second-largest living rhinoceros, behind only the white rhinoceros. Bulls have a head and body length of 368–380 cm (12.07–12.47 ft) with a shoulder height of 163–193 cm (5.35–6.33 ft), while cows have a head and body length of 310–340 cm (10.2–11.2 ft) and a shoulder height of 147–173 cm (4.82–5.68 ft).[18][11] The bull, averaging about 2,070–2,200 kg (4,560–4,850 lb) is heavier than the cow, at an average of about 1,600 kg (3,530 lb).[18][11]

The rich presence of blood vessels underneath the tissues in folds gives them the pinkish colour. The folds in the skin increase the surface area and help in regulating the body temperature.[19] The thick skin does not protect against bloodsucking Tabanus flies, leeches and ticks.[11]

The largest individuals reportedly weigh up to 4,000 kg (8,820 lb).[20]

Distribution and habitat edit

Indian rhinos once ranged across the entire northern part of the Indian subcontinent, along the Indus, Ganges and Brahmaputra River basins, from Pakistan to the Indian-Myanmar border, including Bangladesh and the southern parts of Nepal and Bhutan. They may have also occurred in Myanmar, southern China and Indochina. They inhabit the alluvial grasslands of the Terai and the Brahmaputra basin.[21] As a result of habitat destruction and climatic changes its range has gradually been reduced so that by the 19th century, it only survived in the Terai grasslands of southern Nepal, northern Uttar Pradesh, northern Bihar, northern West Bengal, and in the Brahmaputra Valley of Assam.[22]

The species was present in northern Bihar and Oudh at least until 1770 as indicated in maps produced by Colonel Gentil.[23] On the former abundance of the species, Thomas C. Jerdon wrote in 1867:[24]

This huge rhinoceros is found in the Terai at the foot of the Himalayas, from Bhutan to Nepal. It is more common in the eastern portion of the Terai than the west, and is most abundant in Assam and the Bhutan Dooars. I have heard from sportsmen of its occurrence as far west as Rohilcund, but it is certainly rare there now, and indeed along the greater part of the Nepal Terai; ... Jelpigoree, a small military station near the Teesta River, was a favourite locality whence to hunt the Rhinoceros and it was from that station Captain Fortescue ... got his skulls, which were ... the first that Mr. Blyth had seen of this species, ...

Today, its range has further shrunk to a few pockets in southern Nepal, northern West Bengal, and the Brahmaputra Valley. Its habitat is surrounded by human-dominated landscapes, so that in many areas, it occurs in cultivated areas, pastures, and secondary forests. In the 1980s, Indian rhinos were frequently seen in the narrow plain area of Manas River and Royal Manas National Park in Bhutan.[22]

Populations edit

In 2022, the total Indian rhinoceros population was estimated to be 4014 individuals, up from 2,577 in 2006. Among them 3262 are in India and the remaining 752 are in Nepal and Bhutan. There is no permanent rhino population in Bhutan, but small rhino populations are occasionally known to cross from the Manas National Park or Buxa Tiger Reserve in India.[25]

In India, there are around 2,885 individuals in Assam, including 2,613 in Kaziranga National Park, 125 in Orang National Park, 107 in Pobitora Wildlife Sanctuary and 40 in Manas National Park. West Bengal has a population of 339 individuals, including 287 in Jaldapara National Park and 52 in Gorumara National Park. Only 38 individuals are found in Dudhwa National Park, in Uttar Pradesh.[26][27]

By 2014, the population in Assam increased to 2,544 Indian rhinos, an increase of 27% since 2006, although more than 150 individuals were killed by poachers during these years.[28] The population in Kaziranga National Park was estimated at 2,048 individuals in 2009.[29] By 2009, the population in Pobitora Wildlife Sanctuary had increased to 84 individuals in an area of 38.80 km2 (14.98 sq mi).[30]

In 2015, Nepal had 645 Indian rhinos living in Parsa National Park, Chitwan National Park, Bardia National Park, Shuklaphanta Wildlife Reserve and respective buffer zones in the Terai Arc Landscape as recorded in a survey conducted from 11 April to 2 May 2015. The survey showed that the population of rhinos in Nepal from 2011 to 2015 increased 21% or 111 individuals.[31]

The Indian rhino population, which once numbered as low as 100 individuals in the early 1900s, has increased to more than 3,700 in the year 2021 as per The International Rhino Foundation.[32]

Ecology and behaviour edit

Bulls are usually solitary. Groups consist of cows with calves, or of up to six subadults. Such groups congregate at wallows and grazing areas. They are foremost active in early mornings, late afternoons and at night, but rest during hot days.[11]

They bathe regularly. The folds in their skin trap water and hold it even when they exit wallows.[19] They are excellent swimmers and can run at speeds of up to 55 km/h (34 mph) for short periods. They have excellent senses of hearing and smell, but relatively poor eyesight. Over 10 distinct vocalisations have been recorded. Males have home ranges of around 2 to 8 km2 (0.77 to 3.09 sq mi) that overlap each other. Dominant males tolerate other males passing through their territories except when they are in mating season, when dangerous fights break out.[33] Indian rhinos have few natural enemies, except for tigers, which sometimes kill unguarded calves, but adult rhinos are less vulnerable due to their size. Mynahs and egrets both eat invertebrates from the rhino's skin and around its feet. Tabanus flies, a type of horse-fly, are known to bite rhinos. The rhinos are also vulnerable to diseases spread by parasites such as leeches, ticks, and nematodes like Bivitellobilharzia nairi. Anthrax and the blood-disease sepsis are known to occur.[11] In March 2017, a group of four tigers consisting of an adult male, tigress and two cubs killed a 20-year-old male Indian rhinoceros in Dudhwa Tiger Reserve.[34] Such cases are rare, as Indian rhinoceroses—like most megaherbivores—are mostly invulnerable to predation.[35][36]

Diet edit

Indian rhinos are grazers. Their diet consists almost entirely of grasses (such as Arundo donax, Bambusa tulda, Cynodon dactylon, and Oryza sativa), but they also eat leaves, twigs and branches of shrubs and trees (such as Lagerstroemia indica), flowers, fruits (such as Ficus religiosa), and submerged and floating aquatic plants.[37] They feed in the mornings and evenings. They use their semi-prehensile lips to grasp grass stems, bend the stem down, bite off the top, and then eat the grass. They tackle very tall grasses or saplings by walking over the plant, with legs on both sides and using the weight of their bodies to push the end of the plant down to the level of the mouth. Mothers also use this technique to make food edible for their calves. They drink for a minute or two at a time, often imbibing water filled with rhinoceros urine.[11]

Social life edit

Indian rhinos form a variety of social groupings. Bulls are generally solitary, except for mating and fighting. Cows are largely solitary when they are without calves.[38] Mothers will stay close to their calves for up to four years after their birth, sometimes allowing an older calf to continue to accompany her once a newborn calf arrives. Subadult bulls and cows form consistent groupings, as well.[39] Groups of two or three young bulls often form on the edge of the home ranges of dominant bulls, presumably for protection in numbers. Young cows are slightly less social than the bulls. Indian rhinos also form short-term groupings, particularly at forest wallows during the monsoon season and in grasslands during March and April. Groups of up to 10 rhinos, typically a dominant male with females and calves, gather in wallows.[15]

Indian rhinos make a wide variety of vocalisations. At least 10 distinct vocalisations have been identified: snorting, honking, bleating, roaring, squeak-panting, moo-grunting, shrieking, groaning, rumbling and humphing. In addition to noises, the Indian rhino uses olfactory communication. Adult bulls urinate backwards, as far as 3–4 m (9.8–13.1 ft) behind them, often in response to being disturbed by observers. Like all rhinos, the Indian rhinoceros often defecates near other large dung piles. The Indian rhino has pedal scent glands which are used to mark their presence at these rhino latrines. Bulls have been observed walking with their heads to the ground as if sniffing, presumably following the scent of cows.[15]

In aggregations, Indian rhinos are often friendly. They will often greet each other by waving or bobbing their heads, mounting flanks, nuzzling noses, or licking. Indian rhinos will playfully spar, run around, and play with twigs in their mouths. Adult bulls are the primary instigators in fights. Fights between dominant bulls are the most common cause of rhino mortality, and bulls are also very aggressive toward cows during courtship. Bulls chase cows over long distances and even attack them face-to-face. Indian rhinos use their horns for fighting, albeit less frequently than African rhinos that largely use the incisors of the lower jaw to inflict wounds.[15]

Reproduction edit

 
Cow with calf

Captive bulls breed at five years of age, but wild bulls attain dominance much later when they are larger. In one five-year field study, only one Indian rhino estimated to be younger than 15 years mated successfully. Captive cows breed as young as four years of age, but in the wild, they usually start breeding only when six years old, which likely indicates they need to be large enough to avoid being killed by aggressive bulls.[15] The ovarian cycle lasts 5.5 to 9 weeks on average.[40] Their gestation period is around 15.7 months, and birth interval ranges from 34 to 51 months.[15] An estimated 10% of calves will die before maturity. This is mainly attributed to predatory attacks from tigers (Panthera tigris).[41] In captivity, four Indian rhinos lived over 40 years, the oldest living to be 47.[11]

Threats edit

Habitat degradation caused by human activities and climate change as well as the resulting increase in the floods has caused many Indian rhino deaths and has limited their ranging areas which is shrinking.[1]

Serious declines in quality of habitat have occurred in some areas, due to severe invasion by alien plants into grasslands affecting some populations, and demonstrated reductions in the extent of grasslands and wetland habitats due to woodland encroachment and silting up of beels (swampy wetlands). Grazing by domestic livestock is another cause.[1]

The Indian rhino species is inherently at risk because over 70% of its population occurs at a single site, Kaziranga National Park. Any catastrophic event such as disease, civil disorder, poaching, or habitat loss would have a devastating impact on the Indian rhino's status. However, small population of rhinos may be prone to inbreeding depression.[1]

Poaching edit

Sport hunting became common in the late 19th and early 20th centuries and was the main cause for the decline of Indian rhinoceros populations. Indian rhinos were hunted relentlessly and persistently. Reports from the mid-19th century claim that some British military officers shot more than 200 rhinos in Assam alone. By 1908, the population in Kaziranga National Park had decreased to around 12 individuals.[11] In the early 1900s, the Indian rhinoceros was almost extinct. At present, poaching for the use of horn in traditional Chinese Medicine is one of the main threats that has led to decreases in several important populations.[1] Poaching for the Indian rhino's horn became the single most important reason for the decline of the Indian rhinoceros after conservation measures were put in place from the beginning of the 20th century, when legal hunting ended. From 1980 to 1993, 692 rhinos were poached in India, including 41 rhinos in India's Laokhowa Wildlife Sanctuary in 1983, almost the entire population of the sanctuary.[42] By the mid-1990s, the Indian rhinoceros had been extirpated in this sanctuary.[21] Between 2000 and 2006, more than 150 rhinos were poached in Assam.[28][43] Almost 100 rhinos were poached in India between 2013 and 2018.[44]

In 1950, in Nepal the Chitwan's forest and grasslands extended over more than 2,600 km2 (1,000 sq mi) and were home to about 800 rhinos. When poor farmers from the mid-hills moved to the Chitwan Valley in search of arable land, the area was subsequently opened for settlement, and poaching of wildlife became rampant. The Chitwan population has repeatedly been jeopardised by poaching; in 2002 alone, poachers killed 37 animals to saw off and sell their valuable horns.[45]

Conservation edit

The Indian rhinoceros is listed as vulnerable by the IUCN Red list, as of 2018.[1] Globally, R. unicornis has been listed in CITES Appendix I since 1975. The Indian and Nepalese governments have taken major steps towards Indian rhinoceros conservation, especially with the help of the World Wide Fund for Nature (WWF) and other non-governmental organisations.[1] In 1910, all rhino hunting in India became prohibited.[11]

In 1957, the country's first conservation law ensured the protection of rhinos and their habitat. In 1959, Edward Pritchard Gee undertook a survey of the Chitwan Valley, and recommended the creation of a protected area north of the Rapti River and of a wildlife sanctuary south of the river for a trial period of 10 years.[46] After his subsequent survey of Chitwan in 1963, he recommended extension of the sanctuary to the south.[47] By the end of the 1960s, only 95 rhinos remained in the Chitwan Valley. The dramatic decline of the rhino population and the extent of poaching prompted the government to institute the Gaida Gasti – a rhino reconnaissance patrol of 130 armed men and a network of guard posts all over Chitwan. To prevent the extinction of rhinos, the Chitwan National Park was gazetted in December 1970, with borders delineated the following year and established in 1973, initially encompassing an area of 544 km2 (210 sq mi). To ensure the survival of rhinos in case of epidemics, animals were translocated annually from Chitwan to Bardia National Park and Shuklaphanta National Park since 1986.[45] The Indian rhinoceros population living in Chitwan and Parsa National Parks was estimated at 608 mature individuals in 2015.[36]

Reintroduction to new areas edit

Indian rhinos have been reintroduced to areas where they had previously inhabited but became extinct. These efforts have produced mixed results, mainly due to lack of proper planning and management, sustained effort, adequate security of the introduced animals.[48]

In 1984, five Indian rhinos were relocated to Dudhwa National Park—four from the fields outside the Pobitora Wildlife Sanctuary and one from Goalpara.[22] This has born results and the population has increased to 21 rhinos by 2006.[26] In early 1980s, Laokhowa Wildlife Sanctuary in Assam had more than 70 Indian rhinos which were all killed by poachers. In 2016, two Indian rhinos, a mother and her daughter, were reintroduced to the sanctuary from Kaziranga National Park as part of the Indian Rhino Vision 2020 (IRV 2020) program, but both animals died within months due to natural causes.[44]

Indian rhinos were once found as far west as the Peshawar Valley during the reign of Mughal Emperor Babur, but are now extinct in Pakistan. After rhinos became "regionally extinct" in Pakistan,[49] two rhinos from Nepal were introduced in 1983 to Lal Suhanra National Park, which have not bred so far.[1][22]

In captivity edit

 
Indian rhinoceroses enjoy bathing at Zoo Basel

Indian rhinoceroses were initially difficult to breed in captivity. In the second half of the 20th century, zoos became adept at breeding Indian rhinoceros. By 1983, nearly 40 babies had been born in captivity.[11] As of 2012, 33 Indian rhinos were born at Switzerland's Zoo Basel alone,[50] meaning that most captive animals are related to the Basel population. Due to the success of Zoo Basel's breeding program, the International Studbook for the species has been kept there since 1972. Since 1990, the Indian rhino European Endangered Species Programme is also being coordinated there, with the goal of maintaining genetic diversity in the global captive Indian rhinoceros population.[51]

The first recorded captive birth of an Indian rhinoceros was in Kathmandu in 1826, but another successful birth did not occur for nearly 100 years. In 1925, a rhino was born in Kolkata. No rhinoceros was successfully bred in Europe until 1956 when first European breeding took place when baby rhino Rudra was born in Zoo Basel on 14 September 1956.[11] In June 2009, an Indian rhino was artificially inseminated using sperm collected four years previously and cryopreserved at the Cincinnati Zoo's CryoBioBank before being thawed and used. She gave birth to a male calf in October 2010.[52] In June 2014, the first "successful" live-birth from an artificially inseminated rhino took place at the Buffalo Zoo in New York. As in Cincinnati, cryopreserved sperm was used to produce the female calf, Monica.[53]

Cultural significance edit

The Indian rhinoceros is one of the motifs on the Pashupati seal and many terracotta figurines that were excavated at archaeological sites of the Indus Valley civilisation.[54]

The Rhinoceros Sutra is an early text in the Buddhist tradition, found in the Gandhāran Buddhist texts and the Pali Canon, as well as a version incorporated into the Sanskrit Mahavastu.[55] It praises the solitary lifestyle and stoicism of the Indian rhinoceros and is associated with the eremitic lifestyle symbolized by the Pratyekabuddha.[56]

Europe edit

 
Painting of Indian Rhinoceros by Thomas Daniell (c. 1790)

In the 3rd century, Philip the Arab exhibited an Indian rhinoceros in Rome.[57] In 1515, Manuel I of Portugal obtained an Indian rhinoceros as a gift, which he passed on to Pope Leo X, but which died in a shipwreck off the coast of Italy in early 1516, on the way from Lisbon to Rome. Three artistic representations were prepared of this rhinoceros: A woodcut by Hans Burgkmair, a drawing and a woodcut (Dürer's Rhinoceros) by Albrecht Dürer, all dated 1515.[57] In 1577–1588, Abada was a female Indian rhinoceros kept by the Portuguese kings Sebastian I and Henry I from 1577 to 1580 and by Philip II of Spain from about 1580 to 1588. She was the first rhinoceros seen in Europe after Dürer's Rhinoceros. In about 1684, the first presumably Indian rhinoceros arrived in England.[57] George Jeffreys, 1st Baron Jeffreys spread the rumour that his chief rival Francis North, 1st Baron Guilford had been seen riding on it.[58]

In 1741–1758, Clara the rhinoceros (c. 1738 – 14 April 1758) was a female Indian rhinoceros who became famous during 17 years of touring Europe in the mid-18th century. She arrived in Europe in Rotterdam in 1741, becoming the fifth living rhinoceros to be seen in Europe in modern times since Dürer's rhinoceros in 1515. After tours through towns in the Dutch Republic, the Holy Roman Empire, Switzerland, the Polish–Lithuanian Commonwealth, France, the Kingdom of the Two Sicilies, the Papal States, Bohemia and Denmark, she died in Lambeth, England. In 1739, she was drawn and engraved by two English artists. She was then brought to Amsterdam, where Jan Wandelaar made two engravings that were published in 1747. In the subsequent years, the rhinoceros was exhibited in several European cities. In 1748, Johann Elias Ridinger made an etching of her in Augsburg, and Petrus Camper modelled her in clay in Leiden. In 1749, Georges-Louis Leclerc, Comte de Buffon drew it in Paris. In 1751, Pietro Longhi painted her in Venice.[57]

individuals Indian rhinos once ranged throughout the entire stretch of the Indo Gangetic Plain but excessive hunting and agricultural development reduced its range drastically to 11 sites in northern India and southern Nepal In the early 1990s between 1 870 and 1 895 Indian rhinos were estimated to have been alive Since then numbers have increased due to conservation measures taken by the

species in India the other being Rhinoceros bicornis and stated that the Indian species had two horns while the African species had only one 2 The Indian rhinoceros is a single species Several specimens were described since the end of the 18th century under different scientific names which are all considered synonyms of Rhinoceros unicornis today 3 R indicus by Cuvier 1817 R asiaticus by Blumenbach 1830 R stenocephalus by Gray 1867 R jamrachi by Sclater 1876 R bengalensis by Kourist 1970 4 Etymology edit The generic name rhinoceros is derived through Latin from the Ancient Greek ῥinokerws which is composed of ῥino rhino of the nose and keras keras horn with a horn on the nose 5 The name has been in use since the 14th century 6 7 The Latin word unicornis means one horned 8 Evolution edit Main article Rhinoceros Evolution Ancestral rhinoceroses first diverged from other perissodactyls in the Early Eocene Mitochondrial DNA comparison suggests the ancestors of modern rhinos split from the ancestors of Equidae around 50 million years ago 9 The extant family the Rhinocerotidae first appeared in the Late Eocene in Eurasia and the ancestors of the extant rhino species dispersed from Asia beginning in the Miocene 10 Fossils of R unicornis appear in the Middle Pleistocene In the Pleistocene the genus Rhinoceros ranged throughout South and Southeast Asia with specimens located on Sri Lanka Into the Holocene some rhinoceros lived as far west as Gujarat and Pakistan until as recently as 3 200 years ago 11 The Indian and Javan rhinoceroses the only members of the genus Rhinoceros first appear in the fossil record in Asia during the Early Pleistocene The Indian rhinoceros is known from Early Pleistocene localities in Java South China India and Pakistan 12 Molecular estimates suggest the species may have diverged much earlier around 11 7 million years ago 9 13 Although belonging to the type genus the Indian and Javan rhinoceroses are not believed to be closely related to other rhino species Different studies have hypothesised that they may be closely related to the extinct Gaindatherium or Punjabitherium A detailed cladistic analysis of the Rhinocerotidae placed Rhinoceros and the extinct Punjabitherium in a clade with Dicerorhinus the Sumatran rhinoceros Other studies have suggested the Sumatran rhinoceros is more closely related to the two African species 14 The Sumatran rhino may have diverged from the other Asian rhinos as long ago as 15 million years 10 15 A cladogram showing the relationships of recent and Late Pleistocene

rhinos have a thick grey brown skin with pinkish skin folds and one horn on their snout Their upper legs and shoulders are covered in wart like bumps They have very little body hair aside from eyelashes ear fringes and tail brush Bulls have huge neck folds The skull is heavy with a basal length above 60 cm 24 in and an occiput above 19 cm 7 5 in The nasal horn is slightly back curved with a base of about 18 5 cm 7 3 in by 12 cm 4 7 in that rapidly narrows until a smooth even stem part begins about 55 mm 2 2 in above base In captive animals the horn is frequently worn down to a thick knob 11 The Indian rhino s single horn is present in both bulls and cows but not on newborn calves The horn is pure keratin like human fingernails and starts to show after about six years In most adults the horn reaches a length of about 25 cm 9 8 in but has been recorded up to 57 2 cm 22 5 in in length and 3 051 kg 6 73 lb in weight 15 11 Among terrestrial land mammals native to Asia Indian rhinos

reportedly weigh up to 4 000 kg 8 820 lb 20 Distribution and habitat edit nbsp Indian rhinoceros in Chitwan National Park Nepal Indian rhinos once ranged across the entire northern part of the Indian subcontinent along the Indus Ganges and Brahmaputra River basins from Pakistan to the Indian Myanmar border including Bangladesh and the southern parts of Nepal and Bhutan They may have also occurred in Myanmar southern China and Indochina They inhabit the alluvial grasslands of the Terai and the Brahmaputra basin 21 As a result of habitat destruction and climatic changes its range has gradually been reduced so that by the 19th century it only survived in the Terai grasslands of southern Nepal northern Uttar Pradesh northern Bihar northern West Bengal and in the Brahmaputra Valley of Assam 22 The species was present in northern Bihar and Oudh at least until 1770 as indicated in maps produced by Colonel Gentil 23 On the former abundance of the species Thomas C Jerdon wrote in 1867 24 This huge rhinoceros is found in the Terai at the foot of the Himalayas from Bhutan to Nepal It is more common in the eastern portion of the Terai than the west and is most abundant in Assam and the Bhutan Dooars I have heard from sportsmen of its occurrence as far west as Rohilcund but it is certainly rare there now and indeed along the greater part of the Nepal Terai Jelpigoree a small military station near the Teesta River was a favourite locality whence to hunt the Rhinoceros and it was from that station Captain Fortescue got his skulls which were the first that Mr Blyth had seen of this species Today its range has further shrunk to a few pockets in southern Nepal northern West Bengal and the Brahmaputra Valley Its habitat is surrounded by human dominated landscapes so that in many areas it occurs in cultivated areas pastures and secondary forests In the 1980s Indian rhinos were frequently seen in the narrow plain area of Manas River and Royal Manas National Park in Bhutan 22 Populations edit In 2022 the total Indian rhinoceros population was estimated to be 4014 individuals up from 2 577 in 2006 Among them 3262 are in India and the remaining 752 are in Nepal and Bhutan There is no permanent rhino population in Bhutan but small rhino populations are occasionally known to cross from the Manas National Park or Buxa Tiger Reserve in India 25 In India there are around 2 885 individuals in Assam including 2 613 in Kaziranga National Park 125 in Orang National Park 107 in Pobitora Wildlife Sanctuary and 40 in Manas National Park West Bengal has a population of 339 individuals including 287 in Jaldapara National Park and 52 in Gorumara National Park Only 38 individuals are found in Dudhwa National Park in Uttar Pradesh 26 27 By 2014 the population in Assam increased to 2 544 Indian rhinos an increase of 27 since 2006 although more than 150 individuals were killed by poachers during these years 28 The population in Kaziranga National Park was estimated at 2 048 individuals in 2009 29 By 2009 the population in Pobitora Wildlife Sanctuary had increased to 84 individuals in an area of 38 80 km2 14 98 sq mi 30 In 2015 Nepal had 645 Indian rhinos living in Parsa National Park Chitwan National Park Bardia National Park Shuklaphanta Wildlife Reserve and respective buffer zones in the Terai Arc Landscape as recorded in a survey conducted from 11 April to 2 May 2015 The survey showed that the population of rhinos in Nepal from 2011 to 2015 increased 21 or 111 individuals 31 The Indian rhino population which once numbered as low as 100 individuals in the early 1900s has increased to more than 3 700 in the year 2021 as per The International Rhino Foundation 32 Ecology and behaviour edit nbsp Indian rhinoceros at Kaziranga National Park nbsp Indian rhinoceros in Manas National ParkBulls are usually solitary Groups consist of cows with calves or of up to six subadults Such groups congregate at wallows and grazing areas They are foremost active in early mornings late afternoons and at night but rest during hot days 11 They bathe regularly The folds in their skin trap water and hold it even when they exit wallows 19 They are excellent swimmers and can run at speeds of up to 55 km h 34 mph for short periods They have excellent senses of hearing and smell but relatively poor eyesight Over 10 distinct vocalisations have been recorded Males have home ranges of around 2 to 8 km2 0 77 to 3 09 sq mi that overlap each other Dominant males tolerate other males passing through their territories except when they are in mating season when dangerous fights break out 33 Indian rhinos have few natural enemies except for tigers which sometimes kill unguarded calves but adult rhinos are less vulnerable due to their size Mynahs and egrets both eat invertebrates from the rhino s skin and around its feet Tabanus flies a type of horse fly are known to bite rhinos The rhinos are also vulnerable to diseases spread by parasites such as leeches ticks and nematodes like Bivitellobilharzia nairi Anthrax and the blood disease sepsis are known to occur 11 In March 2017 a group of four tigers consisting of an adult male tigress and two cubs killed a 20 year old male Indian rhinoceros in Dudhwa Tiger Reserve 34 Such cases are rare as Indian rhinoceroses like most megaherbivores are mostly invulnerable to predation 35 36 Diet edit Indian rhinos are grazers Their diet consists almost entirely of grasses such as Arundo donax Bambusa tulda Cynodon dactylon and Oryza sativa but they also eat leaves twigs and branches of shrubs and trees such as Lagerstroemia indica flowers fruits such as Ficus religiosa and submerged and floating aquatic plants 37 They feed in the mornings and evenings They use their semi prehensile lips to grasp grass stems bend the stem down bite off the top and then eat the grass They tackle very tall grasses or saplings by walking over the plant with legs on both sides and using the weight of their bodies to push the end of the plant down to the level of the mouth Mothers also use this technique to make food edible for their calves They drink for a minute or two at a time often imbibing water filled with rhinoceros urine 11 Social life edit nbsp Indian rhinoceros showing its sharp lower incisor teeth used for fighting Indian rhinos form a variety of social groupings Bulls are generally solitary except for mating and fighting Cows are largely solitary when they are without calves 38 Mothers will stay close to their calves for up to four years after their birth sometimes allowing an older calf to continue to accompany her once a newborn calf arrives Subadult bulls and cows form consistent groupings as well 39 Groups of two or three young bulls often form on the edge of the home ranges of dominant bulls presumably for protection in numbers Young cows are slightly less social than the bulls Indian rhinos also form short term groupings particularly at forest wallows during the monsoon season and in grasslands during March and April Groups of up to 10 rhinos typically a dominant male with females and calves gather in wallows 15 Indian rhinos make a wide variety of vocalisations At least 10 distinct vocalisations have been identified snorting honking bleating roaring squeak panting moo grunting shrieking groaning rumbling and humphing In addition to noises the Indian rhino uses olfactory communication Adult bulls urinate backwards as far as 3 4 m 9 8 13 1 ft behind them often in response to being disturbed by observers Like all rhinos the Indian rhinoceros often defecates near other large dung piles The Indian rhino has pedal scent glands which are used to mark their presence at these rhino latrines Bulls have been observed walking with their heads to the ground as if sniffing presumably following the scent of cows 15 In aggregations Indian rhinos are often friendly They will often greet each other by waving or bobbing their heads mounting flanks nuzzling noses or licking Indian rhinos will playfully spar run around and play with twigs in their mouths Adult bulls are the primary instigators in fights Fights between dominant bulls are the most common cause of rhino mortality and bulls are also very aggressive toward cows during courtship Bulls chase cows over long distances and even attack them face to face Indian rhinos use their horns for fighting albeit less frequently than African rhinos that largely use the incisors of the lower jaw to inflict wounds 15 Reproduction edit nbsp Cow with calf Captive bulls breed at five years of age but wild bulls attain dominance much later when they are larger In one five year field study only one Indian rhino estimated to be younger than 15 years mated successfully Captive cows breed as young as four years of age but in the wild they usually start breeding only when six years old which likely indicates they need to be large enough to avoid being killed by aggressive bulls 15 The ovarian cycle lasts 5 5 to 9 weeks on average 40 Their gestation period is around 15 7 months and birth interval ranges from 34 to 51 months 15 An estimated 10 of calves will die before maturity This is mainly attributed to predatory attacks from tigers Panthera tigris 41 In captivity four Indian rhinos lived over 40 years the oldest living to be 47 11 Threats editHabitat degradation caused by human activities and climate change as well as the resulting increase in the floods has caused many Indian rhino deaths and has limited their ranging areas which is shrinking 1 Serious declines in quality of habitat have occurred in some areas due to severe invasion by alien plants into grasslands affecting some populations and demonstrated reductions in the extent of grasslands and wetland habitats due to woodland encroachment and silting up of beels swampy wetlands Grazing by domestic livestock is another cause 1 The Indian rhino species is inherently at risk because over 70 of its population occurs at a single site Kaziranga National Park Any catastrophic event such as disease civil disorder poaching or habitat loss would have a devastating impact on the Indian rhino s status However small population of rhinos may be prone to inbreeding depression 1 Poaching edit Main article Rhino poaching in Assam nbsp Taxidermied specimens American Museum of Natural History Sport hunting became common in the late 19th and early 20th centuries and was the main cause for the decline of Indian rhinoceros populations Indian rhinos were hunted relentlessly and persistently Reports from the mid 19th century claim that some British military officers shot more than 200 rhinos in Assam alone By 1908 the population in Kaziranga National Park had decreased to around 12 individuals 11 In the early 1900s the Indian rhinoceros was almost extinct At present poaching for the use of horn in traditional Chinese Medicine is one of the main threats that has led to decreases in several important populations 1 Poaching for the Indian rhino s horn became the single most important reason for the decline of the Indian rhinoceros after conservation measures were put in place from the beginning of the 20th century when legal hunting ended From 1980 to 1993 692 rhinos were poached in India including 41 rhinos in India s Laokhowa Wildlife Sanctuary in 1983 almost the entire population of the sanctuary 42 By the mid 1990s the Indian rhinoceros had been extirpated in this sanctuary 21 Between 2000 and 2006 more than 150 rhinos were poached in Assam 28 43 Almost 100 rhinos were poached in India between 2013 and 2018 44 nbsp George V and Chandra Shumsher JBR with a slain rhino during a hunt December 1911 In 1950 in Nepal the Chitwan s forest and grasslands extended over more than 2 600 km2 1 000 sq mi and were home to about 800 rhinos When poor farmers from the mid hills moved to the Chitwan Valley in search of arable land the area was subsequently opened for settlement and poaching of wildlife became rampant The Chitwan population has repeatedly been jeopardised by poaching in 2002 alone poachers killed 37 animals to saw off and sell their valuable horns 45 Conservation editThe Indian rhinoceros is listed as vulnerable by the IUCN Red list as of 2018 1 Globally R unicornis has been listed in CITES Appendix I since 1975 The Indian and Nepalese governments have taken major steps towards Indian rhinoceros conservation especially with the help of the World Wide Fund for Nature WWF and other non governmental organisations 1 In 1910 all rhino hunting in India became prohibited 11 In 1957 the country s first conservation law ensured the protection of rhinos and their habitat In 1959 Edward Pritchard Gee undertook a survey of the Chitwan Valley and recommended the creation of a protected area north of the Rapti River and of a wildlife sanctuary south of the river for a trial period of 10 years 46 After his subsequent survey of Chitwan in 1963 he recommended extension of the sanctuary to the south 47 By the end of the 1960s only 95 rhinos remained in the Chitwan Valley The dramatic decline of the rhino population and the extent of poaching prompted the government to institute the Gaida Gasti a rhino reconnaissance patrol of 130 armed men and a network of guard posts all over Chitwan To prevent the extinction of rhinos the Chitwan National Park was gazetted in December 1970 with borders delineated the following year and established in 1973 initially encompassing an area of 544 km2 210 sq mi To ensure the survival of rhinos in case of epidemics animals were translocated annually from Chitwan to Bardia National Park and Shuklaphanta National Park since 1986 45 The Indian rhinoceros population living in Chitwan and Parsa National Parks was estimated at 608 mature individuals in 2015 36 Reintroduction to new areas edit Indian rhinos have been reintroduced to areas where they had previously inhabited but became extinct These efforts have produced mixed results mainly due to lack of proper planning and management sustained effort adequate security of the introduced animals 48 In 1984 five Indian rhinos were relocated to Dudhwa National Park four from the fields outside the Pobitora Wildlife Sanctuary and one from Goalpara 22 This has born results and the population has increased to 21 rhinos by 2006 26 In early 1980s Laokhowa Wildlife Sanctuary in Assam had more than 70 Indian rhinos which were all killed by poachers In 2016 two Indian rhinos a mother and her daughter were reintroduced to the sanctuary from Kaziranga National Park as part of the Indian Rhino Vision 2020 IRV 2020 program but both animals died within months due to natural causes 44 Indian rhinos were once found as far west as the Peshawar Valley during the reign of Mughal Emperor Babur but are now extinct in Pakistan After rhinos became regionally extinct in Pakistan 49 two rhinos from Nepal were introduced in 1983 to Lal Suhanra National Park which have not bred so far 1 22 In captivity edit nbsp Indian rhinoceroses enjoy bathing at Zoo Basel Indian rhinoceroses were initially difficult to breed in captivity In the second half of the 20th century zoos became adept at breeding Indian rhinoceros By 1983 nearly 40 babies had been born in captivity 11 As of 2012 33 Indian rhinos were born at Switzerland s Zoo Basel alone 50 meaning that most captive animals are related to the Basel population Due to the success of Zoo Basel s breeding program the International Studbook for the species has been kept there since 1972 Since 1990 the Indian rhino European Endangered Species Programme is also being coordinated there with the goal of maintaining genetic diversity in the global captive Indian rhinoceros population 51 The first recorded captive birth of an Indian rhinoceros was in Kathmandu in 1826 but another successful birth did not occur for nearly 100 years In 1925 a rhino was born in Kolkata No rhinoceros was successfully bred in Europe until 1956 when first European breeding took place when baby rhino Rudra was born in Zoo Basel on 14 September 1956 11 In June 2009 an Indian rhino was artificially inseminated using sperm collected four years previously and cryopreserved at the Cincinnati Zoo s CryoBioBank before being thawed and used She gave birth to a male calf in October 2010 52 In June 2014 the first successful live birth from an artificially inseminated rhino took place at the Buffalo Zoo in New York As in Cincinnati cryopreserved sperm was used to produce the female calf Monica 53 Cultural significance edit nbsp The Pashupati seal showing a seated figure that is surrounded by animals including the Indian rhinoceros c 2350 2000 BCE The Indian rhinoceros is one of the motifs on the Pashupati seal and many terracotta figurines that were excavated at archaeological sites of the Indus Valley civilisation 54 The Rhinoceros Sutra is an early text in the Buddhist tradition found in the Gandharan Buddhist texts and the Pali Canon as well as a version incorporated into the Sanskrit Mahavastu 55 It praises the solitary lifestyle and stoicism of the Indian rhinoceros and is associated with the eremitic lifestyle symbolized by the Pratyekabuddha 56 Europe edit nbsp Durer s Rhinoceros 1515 nbsp Painting of Indian Rhinoceros by Thomas Daniell c 1790 In the 3rd century

1588 She was the first rhinoceros seen in Europe after Durer s Rhinoceros In about 1684 the first presumably Indian rhinoceros arrived in England 57 George Jeffreys 1st Baron Jeffreys spread the rumour that his chief rival Francis North 1st Baron Guilford had been seen riding on it 58 In 1741 1758 Clara the rhinoceros c 1738 14 April 1758 was a female Indian rhinoceros who became famous during 17 years of touring Europe in the mid 18th century She arrived in Europe in Rotterdam in 1741 becoming the fifth living rhinoceros to be seen in Europe in modern times since Durer s rhinoceros in 1515 After tours through towns in the Dutch Republic the Holy Roman Empire Switzerland the Polish Lithuanian Commonwealth France the Kingdom of the Two Sicilies the Papal States Bohemia and Denmark she died in Lambeth England In 1739 she was drawn and engraved by two English artists She was then brought to Amsterdam where Jan Wandelaar made two engravings that were published in 1747 In the subsequent years the rhinoceros was exhibited in several European cities In 1748 Johann Elias Ridinger made an etching of her in Augsburg and Petrus Camper modelled her in clay in Leiden In 1749
