The aquatic lifestyle of the beaver requires it to have some special adaptations to help it survive and thrive. Like most semi-aquatic animals beavers have webbed feet, but they also have very oily fur to repel water and to keep them warm. One of the most famous features of a beaver is its large, powerful tail. They use their tail as a rudder to help them swim like a torpedo underwater. Not only does their tail help with swimming, it helps with talking to; beavers slap their tail on the water to communicate with other beavers in their colony and with intruders of their territory.
When building dams and lodges, usually located in the middle of ponds and streams, they can change the direction of the water flow.Their lodges provide protection from both predators and the elements with their underwater entrances. Sometime this is helpful to protect watersheds for migratory birds and other species, but more times than not it can severely affect the chemical and sedimentary makeup of the ecosystem.
If you’re as busy a beaver make sure to relax this weekend!
