The leopard seal, also called the sea leopard, is a fierce hunter of Antarctic waters. With powerful jaws, leopard seals feed on fish, penguins, squid and smaller seals. Their patterned fur -- dark on top and lighter on their underbellies -- acts as camouflage in the water. Lucky for them, a thick layer of blubber provides insulation from the cold.
