Leopard seal (Hydrurga leptonyx)
Antarctica’s largest seal, the leopard seal is the only seal that regularly eats meat. Its massive jaws hold special teeth designed for stabbing and shearing prey such as other seals, fish, and squid. Penguins, a mealtime favorite, are too fast for the leopard seal on land—but not in water. There, the leopard seal’s streamlined body and long fore-flippers help it chase down penguins as well as crabeater seals.
