(萌妹社区Org.com) -- Scientists have discovered a new species of sea snake in the Gulf of Carpenteria, northern Australia, which is unique in having raised scales.

The finding published in Zootaxa today by Associate Professor Bryan Fry from The University of Queensland's (UQ) School of Biological Sciences and colleagues from The University of Adelaide, will provide important clues about evolution.

Associate Professor Fry said that Hydrophis donaldii had evaded earlier discovery as it prefers estuarine habitats that are poorly surveyed and not targeted by commercial fisheries.

鈥淲eipa really is one of the last sea snake 鈥楽erengetis'. We can see over 200 sea snakes in a single night's hunting, whereas sea snake populations have really crashed elsewhere through over-fishing removing their prey and also the snakes drowning in trawling nets,鈥� Associate Professor Fry said.

Associate Professor Fry said the findings extend beyond simply discovering a rare animal.

鈥淎ll venomous animals are bio-resources and have provided sources of many life-saving medications, such as treatments for high-blood pressure and diabetes.

鈥淭his reinforces why we need to conserve all of nature as the next billion dollar wonder-drug may come from as unlikely a source as sea snake 惫别苍辞尘.鈥�

The snake has been given the scientific name Hydrophis donaldii to honour Associate Professor Fry's long-time boat captain David Donald.

鈥淨uite simply we would not have found this snake without Dave's unique knowledge of the area. I told him we wanted to survey as many distinct types of habitat as possible and he guided us to the perfect spots,鈥� Associate Professor Fry said.

The snake has been given the common-name 鈥榬ough-scaled sea snake' to reflect the unique scalation.

鈥淲e don't know why it has been evolutionarily selected to have such unique scalation, but we will next study its ecology to learn more about it.鈥�
