There are nearly fifty different kinds of sea snakes, all with one exception living in waters between the Persian Gulf and Polynesia. The Yellow-bellied Sea Snake lives in Africa and Mexico.
Sea snakes, with black rings or bars on its blue body, belong to the Hydropphidae family. It has a wide tail which is uses as an oar when swimming, and although it comes to the surface to breathe it can dive to great depths to catch its fishy food.
Female snakes hatch out their eggs on a sandy beach and all the sea snakes are far more poisonous than their land cousins – so beware!
