What monotremes looks like where they live and how it moves?

Monotremes, such as the platypus and echidna, are unique egg-laying mammals. The platypus has a streamlined body covered in waterproof fur, a flat bill, and webbed feet, which aid in swimming in rivers and streams. Echidnas have spiny coats and burrow in the ground, using their strong claws to dig. Both species move with a combination of waddling on land and swimming or digging, depending on their environment.
