The platypus is a mammal. It lives in rivers and streams in eastern Australia. Its home is near fresh water.
The platypus eats insect larvae, shrimp and worms. It dives to the riverbed and scoops up food, storing it in its cheeks.
The platypus has a soft bill that senses tiny electric signals. This lets it find prey underwater with its eyes, ears and nose shut. It is about 50 centimeters long.
The platypus is a mammal that lays eggs, and the young drink milk after they hatch.
