YELLOW BELLIED SEA SNAKE Pelamis platurus (Linnaeus, 1766)
Commonly called the Pelagic Sea Snake, this is the only truly ocean going species of Sea Snake. It is found throughout the Indian and Pacific oceans and is commonly found in waters along the entire west, north and east coasts. This dangerous species grows to about 70 cm.
The scalation is imbricate with 47-69 mid body rows, 264-406 ventrals.
This snake has killed a number of people, although to date no Australians are known to have died from the bite of this snake. The venom is strongly neurotoxic (nerve killing).
No Sea Snake can cross land well, but this species can do so better than most and so if found on a beach should be treated with extra caution.
Yellow Bellied Sea Snakes feed on small fish and young eels. This species is known to occur in large aggregations in some areas, numbering hundreds or even thousands of individuals. The purpose of these aggregations is not known.
This species produces from 1 to 6 live young, although its' breeding biology is essentially unknown.
