About the North-western Mangrove Sea Snake
Grey's mudsnake (Ephalophis greyae), also known commonly as Grey's sea snake, the mangrove seasnake, and the north-western mangrove sea snake, is a species of venomous snake in the subfamily Hydrophiinae of the family Elapidae. The species is endemic to northwestern Australia.
Its specific name, greyae, has also been spelled greyi; however, it was named after a Beatrice Grey who collected the holotype, necessitating a feminine possessive. E. greyae is found along the northwestern coast of the Australian state of Western Australia, from Shark Bay to Kimberley Region.
The preferred natural habitats of E. greyae are mud flats, salt flats, the marine intertidal zone, and the marine neritic zone, to a depth of 10 m (33 ft). A small species of sea snake, E. greyae may attain a total length (including tail) of 66 cm (26 in).
E. greyae preys upon fishes, especially gobies and their eggs. E. greyae is viviparous. Cogger HG (2014). Reptiles and Amphibians of Australia, Seventh Edition. Clayton, Victoria, Australia: CSIRO Publishing. xxx + 1,033 pp. ISBN 978... Wikipedia →
