1. Furry Webbed Feet: The platypus has unique front and rear feet with specialized webbing. The front feet have larger, more flexible webbing suited for swimming, while the hind feet have smaller webbing better suited for walking on land. These well-adapted feet help propel the platypus through water with powerful strokes during swimming.
2. Tail: The platypus also uses its paddle-like tail for propulsion. It's a flattened and broad tail that helps the platypus move in the water efficiently. The muscular tail provides stability and steering while enhancing the swimming capabilities of this semi-aquatic mammal.
