Etymology edit
The specific name, annandalei, is in honor of Scottish herpetologist Nelson Annandale.[3]
Geographic range edit
H. annandalei is found in the Indian Ocean, in waters off Indonesia (Borneo, Java), western Malaysia, Singapore, Cambodia, Thailand, and southern Vietnam.[1][2]
Habitat edit
The preferred natural habitats of H. annandalei are shallow muddy coastal waters.[1]
Description edit
H. annandalei may attain a snout-to-vent length (SVL) of 52 cm (20 in). Its coloration, which consists of dark crossbands on a bluish grey ground color dorsally, and which is uniform pale yellow or cream ventrally, is similar to that of other sea snakes. However, K. annandalei can be identified by its high number of dorsal scale rows, 74–93 at midbody.[4]
Reproduction edit
H. annandalei is viviparous.[2]
