The platypus has four legs. When on land, it walks. When in water, it swims. Its feet have retractable webbing between the toes. This means it can swim effectively, but it can also dig on land because the webbing retracts to expose the sharp claws.
penguins swim and platypus's don't
The platypus walks with a "waddling" movement.
They don't. Platypuses swim with a platypus's tail. The beaver's tail is broader and flatter than a platypus's, and covered with special scales. The platypus's tail is covered with dense fur.
Like many semi-aquatic mammals, the platypus has a streamlined body. This enables the platypus to swim and dive faster.
Sources vary as to how fast a platypus swims. They have been recorded as swimming and diving at a rate of about 12 metres (40 feet) per minute. The Australian Museum website states that the platypus can swim at a rate of 1 metre per second in fast-moving waters, dropping to 0.4 metres per second when hunting for food.

It is instinctive for a young platypus to be able to swim when it gets old enough. However, the mother certainly teaches it how to find food.
