* Dive and hide: Beavers are expert swimmers and can stay underwater for a surprisingly long time. If they feel threatened, they will dive into the water and hide in their lodge or burrow.
* Use their teeth: Beavers have powerful teeth that they use to cut down trees and build dams. They can also use their teeth to defend themselves.
* Slap their tail: Beavers have a large, flat tail that they can slap on the water to create a loud noise that warns other beavers of danger.
* Release a foul-smelling musk: Beavers have a special gland that produces a strong, musky smell that can deter predators.
* Stay quiet and still: Beavers are masters of camouflage and will often stay perfectly still to avoid being detected.
It's important to remember that beavers are wild animals and should be observed from a safe distance.
