How do platypus retract there webbing?

Platypuses have webbed feet that help them swim efficiently, but they can retract the webbing while on land. This is achieved through a system of muscles and tendons that pull the skin between their toes, allowing the claws to be exposed for digging or walking. When they are in the water, the webbing extends to aid in swimming, and when they are on land, the webbing can be drawn back to enhance traction. This unique ability is one of the many adaptations that make the platypus a fascinating creature.
