A very unique mammal found along the eastern edge of Australia – the Duck-Billed Platypus. These semi-aquatic creatures are bottom feeders that hunt for insects, larvae, worms and shellfish. With their webbed feet and strong tail they move very gracefully through the water in search of prey. Like the Echidna, the Platypus is the only other mammal that lay eggs. Male Platypuses possess venomous stingers in their rear feet.
