The venom apparatus of the egg eating sea snakes is said to be degenerated by some sources.Other sources say, that they still have venom. Thes snakes still have fangs, even though they are very tiny and hardly functional. It is better not to risk a bite.


This sea snake feeds exclusively fish eggs and blennies and gobies. It is active in daylight only. Prey is mainly located via smell, not by vision.
