Platypus

The platypus is a unique aquatic mammal native to Australia, known for its distinctive features. It has a soft, otter-like body, webbed feet for swimming, and a bill resembling that of a duck, which contains electroreceptors to detect prey. Unlike most mammals, the male platypus has a spur on its hind leg that delivers venom. It lays eggs instead of giving birth to live young, a rare trait among mammals. These adaptations make the platypus a fascinating example of evolutionary diversity, combining characteristics of mammals, reptiles, and birds.
