The furry platypus, a native of Australia and Tasmania, looks like a mammal at first glance. But upon studying it more closely, one recognizes the birdlike characteristics that have puzzled scientists. For instance, the platypus has webbed feet like some water bird. It also has a leathery bill like a duck. That's how the animal gets its name, the "duck-billed platypus." In addition, the semi-aquatic platypus lays eggs like a bird.
