Tiburonia is a genus of jellyfish in the familyUlmaridae. It was reported in 2003, following the discovery of its only species yet identified, Tiburonia granrojo. It was discovered by a crew from MBARI led by George Matsumoto.[2] Pieces of the medusae (bell margin and arms) were collected for morphological analysis, which eventually led to sequencing and taxonomic identification.[1] The discovery of this organism led to not only a new species, but a new subfamily of Ulmaridae, called Tiburoniinae.[2] Its genus was named Tiburonia after the ROV the crew were using, called Tiburon, meaning "shark" in Spanish. Because of this ROVs distinct maneuverability, all angles of the organisms were able to be observed, which is particularly important to the study of gelatinous pelagic invertebrates.[1] Its species name was originally to be called "big ugly", but Kirsten Matsumoto, George Matsumoto's wife, raised objections to this name, and renamed it granrojo, meaning "big red" in Spanish, leading to its English-language name, the Big Red Jellyfish.[3]
Tiburonia granrojo is one of the largest sea jellies and unusual in a number of ways. They live at ocean depths of 600 to 1,500 metres (2,000 to 4,900 ft) and have been found across the Pacific Ocean in the Gulf of California, Monterey Bay, Hawaii and Japan. It is very likely that these jellies are exhibiting deep-sea gigantism. They can grow up to 76 centimetres (30 in) in diameter,[1] according to the California Academy of Sciences, and have thick fleshy 4-7 oral arms in place of the long tentacles found in most jellies. The radial canals of the Tiburonia granrojo do not narrow. This fact, along with the length of the arms and the shape of the bell, separates Tiburoniiae from other genera of Ulmaridae.[1] All specimens that have been observed live in temperatures between 2.7–4.9C, salinities between 34.1 and 34.5 PSU, and oxygen contents between 0.15 and 1.22 ml of O2 1^-1.[1] The entire jellyfish is deep red in color.[4]
To date, only 23 members of the species have been found and only one—a small specimen under 15 centimetres (6 in)—has been retrieved for further study. Several high resolution videos of granrojo have been taken by remote controlled submarines. The discovery was announced by Dr. Matsumoto and colleagues in Marine Biology in 2003.[1] The first specimen of the species was obtained around the Japan trench and was placed in the National Science Museum in Tokyo.[5]
