  • Fun Facts
  • The word beaver comes from words in the old European languages that mean "brown".
  • A beaver can hold its breath for up to 15 minutes, though they often aren't under water for longer than five minutes.
  • The home of a beaver is called a lodge, and the entrance is usually underwater.
  • Beaver dams are normally range in length from a few feet to 330 feet in length.
  • The largest beaver dam known to exist is in Wood Buffalo National Park in Alberta, Canada and measures 2,790 feet in length.
  • Other than humans, no other animal alive today shapes the environment as much as beavers do.
  • Beavers will make "canals" to help move the trees and branches they cut down.
  • Beavers teeth are orange on the outside because instead of enamel protecting the teeth, they have small amounts of iron in their teeth, perfect for helping them to cut through the wood of trees.
