Beavers Senses Shutdown

A beaver has the ability to shut down two of their senses, smell and hearing.

A beaver’s nose has a special inner flap that seals out water when the beaver is submerged. Adult beavers can hold their breath under water for 15 minutes.  Beaver ears also have inner flaps that seal out water when they are swimming. They have oversized auditory canals, which allow them to pick up sounds and vibrations under water that may indicate danger.
