An online resource based on the award-winning nature guide –


If there’s any species that knows how to survive a heat wave, it’s beavers! More at home in water than on land, the beaver can hold its breath for up to 15 minutes, and swim up to half a mile under water. Beavers also have valves in their nose and ears that automatically close when beavers are submerged, and transparent nictitating membranes that act as a third eyelid, covering and protecting  their  eyes under water.

  1. Love this picture Mary. I enjoy watching the beavers in the bay area of our lake. They kind of remind me aquatic groundhogs.
