Everyone is aware of just how bizarre the platypus can be. In fact, Australia alone has some of the weirdest animals that aren’t found anywhere else on Earth. So what makes the platypus so strange? First is its appearance, and it looks like a beaver that had a duck’s bill grafted onto it. Secondly, it’s a warm-blooded mammal that lays eggs, which no other mammal in the world does. Lastly, the males are actually equipped with poisoned claws on their front feet in order to fend off predators. It’s definitely one of the strangest animals out there.
