Do Beavers Use Echolocation?

No they do not. Beavers are not capable of echolocation, which is the practice of using sound echoes to locate and identify the environment.

However, beavers do use sound as a defense mechanism. When threatened, the beaver will dive into the water while slapping its tail hard on the surface. This makes a large booming sound that may scare the predator away while simultaneously alerting other beavers in the area.
