How do muskrats adapt?

Muskrat Adaptations: The exceptionally long tail of this animal has vertical scales all over it. This unusual adaptation helps the muskrat to swim, and hence makes it one of the few semi-aquatic rodents in the world. When muskrats walk on the land, their tail rubs on the ground and makes obvious marks on it. These muskrat tracks make the task of tracking these rodents easier for wildlife enthusiasts and hunters. Even their fur has two layers, which helps them to adapt to the cold water in which they swim.
