The Ornithorhynchus, commonly known as the platypus, is a unique mammal native to eastern Australia and Tasmania. It is one of the few monotremes, meaning it lays eggs instead of giving birth to live young. The platypus has a distinctive appearance, featuring a duck-like bill, webbed feet, and a flat tail, which help it navigate aquatic environments. Platypuses are semi-aquatic and primarily feed on insects, larvae, and small crustaceans. They use their sensitive bill to detect prey in the water, relying on electroreception to find food. This remarkable adaptation allows them to thrive in their natural habitat, making them a fascinating subject of study in the animal kingdom.
