Facts

  • Beavers' teeth are durable and grow constantly throughout their lives, a necessity for gnawing through trees.
  • The front surface of their incisor teeth is covered by a thick and brightly colored orange enamel. The inner surface of these teeth is white and is not as strong and durable. The white back wears faster than the orange front, creating a sharp, chisel like tooth perfect gnawing and scraping.
  • Their noses and ears have valves that close to keep out water, and their throat can be sealed tight by its tongue, helping it carry and chew sticks underwater.
  • Beavers are considered the best builders among rodents. They construct dams with mud, brush, stones, poles, and vegetation.
  • When a beaver slaps its tail on the water, the sound can be heard up to a mile away.
  • The beaver is North America's largest rodent. It is the world's second largest, after the capybara.
