When you see the sea lion, he is usually wet and his fine fur coat is slicked down close to his smooth body. But there are times when the fat fellow likes to sun bathe and he lolls for hours at a time on a rocky ledge above the pounding surf.
At such times, his fine fur coat becomes dry and you see what seems to be a ruff around his neck. Actually, this is a mane of rather longish curly hair and the sea lion gets his name because, like the king of beasts, he has a mane.
