Open encyclopedia reference
Aipysurus eydouxii, commonly known as the beaded sea snake, the marbled seasnake, and the spine-tailed seasnake, is a species of venomous snake in the family Elapidae. A. eydouxii is unusual amongst sea snakes in that it feeds almost exclusively on fish eggs. As part of this unusual diet, this species has lost its fangs, and the venom glands are almost entirely atrophied.
