Baby platypus have such soft velvety fur. These are unusual animals from Australia. When early colonizers of Australia reported on platypuses, these animals were thought to be an elaborate fraud. Platypus are the only mammals that lay eggs rather than give birth to young, they have bills like a duck, tails like a beaver and feet like an otter. Platypuses are also the only venomous mammal. The male platypus has a spur on its hind foot that can deliver venom that causes significant pain to humans. Thankfully they are now protected and no longer killed for their fur. How could anyone kill them for their fur?!? They need it.
