What is a platypus?

A platypus is a unique mammal native to eastern Australia. It has a duck-like bill, webbed feet, and a flat tail. Platypuses are semiaquatic, living in streams and rivers, and they feed on small insects, crustaceans, and other small aquatic animals.

One of the most unusual things about platypuses is that they lay eggs instead of giving birth to live young. They are also one of the few mammals that can produce venom. Male platypuses have venomous spurs on their hind legs that they use to defend themselves against predators and to establish dominance over other males during mating season.
