Adaptations

Beavers adapt to winter by keeping fat in their tail as well as finding food and hiding it underwater so they have food in the winter. Their blood vessels provide heat and block the large amount of heat they lose in the winter. Winter is the hardest time for beavers to adapt to the environment.



In a habitat with water the beaver has a special membranes that help their eyes in cold temperatures, this membrane slides over the eye. Beavers also have a valve that closes in their nose and ears so that no water can get in. They will build dams or lodges so that they have somewhere to live when it gets real cold out or if it gets to hot out. When beavers leave their damn and move onto another area that area eventually becomes grassy land which will attract their predators. Their predators are raccoons, otters, and wading birds.
