Leopard Seals
Seals may seem like gentle, blubbery sea puppies, but they have us fooled. They have a dangerous streak. Leopard seals are large, carnivorous mammals that are native to the Southern Ocean surrounding Antarctica. They are named for their distinctive spotted coat and are known for their powerful jaws and sharp teeth. Leopard seals are one of the top predators in the Antarctic ecosystem and are known to prey on a variety of other animals, including seals, penguins, and fish. Even though they have cute faces and whiskers, they’re still aggressive predators that have been known to drown human beings. One researcher was killed in Antarctic waters after an aggressive leopard seal attacked him while snorkeling. Seals will kill any other warm-blooded prey, and that includes other seals (via Best Life Online).
