Emydocephalus is a genus of sea snakes in the family Elapidae. Unlike most sea snakes, all species of Emydocephalus, have an absence of teeth on their dentary and palatine bones, and lack venom. The dentary and palantine bones bear only a row of papillae. Emydocephalus does, however, bear fangs and many small pterygoid teeth.[2] This reduced dentition is due to their diet consisting almost entirely of fish eggs.
Etymology
The generic name, Emydocephalus, is from the Greek words ὲμύς (emys) meaning "turtle", and κεφαλή (kephale) meaning "head".[3]
Geographic range
Species of the genus Emydocephalus are found in East Asia, Southeast Asia, and Australasia.[4]
Species
Emydocephalus has three recognized species.
- Emydocephalus annulatus Krefft, 1869
- Emydocephalus ijimae Stejneger, 1898
- Emydocephalus orarius Nankivell, Goiran, Hourston, Shine, Rasmussen, Thomson, & Sanders, 2020[5]
