               SEA SNAKE






            Lots of the animals in the ocean look like snakes, but
            real sea snakes are venomous reptiles that breathe air. This
            usually keeps them near the surface, although they can
            close their nostrils to dive deeper. They have a paddlelike
            tail to help them swim and most give birth to live young
            underwater—unlike other sea reptiles, they do not have to
            go to land to lay eggs. This makes them the only reptiles
            that spend their entire lives at sea.
