That's the pig-nosed turtle, Carettochelys insculpta. I learned about it from an article at Australian Geographic which told me all kinds of interesting facts about this species: It's the only surviving member of the family carettochelyidae, it's an evolutionary transition between land and water turtles, and it's very tasty and could go extinct if hunting isn't curtailed.
But they couldn't tell me what I really wanted to know: If I posted this, would a whole bunch of you comment "That's not ugly, that's cute!"?
