The platypus is one of only three species of mammals that lay eggs. It has a fur-covered body, webbed feet, and a wide beak. It looks sort of like a beaver with a bird’s beak. Platypuses find their food at the bottom of the lakes and rivers where they live. They use their sensitive beak to feel for and find food. The female platypus lays her eggs in a long burrow that she will dig. She will lay, curled up around the two or three eggs she laid until they hatch. The babies live off their mother’s milk until they reach about five months old. Male platypuses have a defense against predators: Their hind legs have poisonous spurs, which can leave a painful wound.
