Emydocephalus is a genus of sea snakes, also known as turtle-headed sea snakes, in the family Elapidae. The genus is one of a small group of the viviparous sea snakes (Hydrophiinae: Hydrophiini) with Aipysurus. Unlike most sea snakes, the species that make up Emydocephalus lack teeth on their dentary and palatine bones. They also lack venom, making them the only non-venomous elapids. 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. Due to their prey being small and immobile, they exhibit a foraging strategy different from most snakes, where they forage more frequently but consume smaller quantities.[3]
Geographic range
Species of the genus Emydocephalus are found in East Asia, Southeast Asia, and Australasia.[5]
