Pig-nosed turtle

As the only living member of the family Carettochelyidae, the pig-nosed turtle is one of a kind — and not just because of its distinctive snout. Unlike most freshwater turtles, these guys have flippers which more closely resemble those of marine turtles, making them almost entirely aquatic.

Interestingly, they are omnivorous, and have even been known to eat dead kangaroos or cattle that end up in streams and rivers.
