Duck-billed platypus is an egg-laying mammal. It is found in the rivers in Eastern Australia and Tasmania. It is a beaver-like monotreme about 50–60 cm long and well adapted to live in water. Usually, two eggs are laid at a time. The female curls around them for incubation and remains inactive for about two weeks. Newly hatched young ones are very immature, naked, blind and each is 2.5 cm long.
