Here's a bit more about their feet:
* Webbed: The toes on their feet are connected by webbing, creating a large, paddle-like surface for swimming.
* Claws: They also have sharp claws on their feet, which help them to dig burrows and walk on land.
* Two pairs: Platypuses have two pairs of webbed feet – one in the front and one in the back.
* Retractible webbing: The webbing on their feet is actually retractable, allowing them to walk more easily on land. When they swim, the webbing expands, and when they walk, the webbing retracts.
