Here's a breakdown:
* Alarm: The loud, resounding slap of their tail serves as a warning signal to other beavers in the area. It alerts them to potential danger like predators or intruders.
* Communication: The tail slap is also used for other communication purposes, such as:
* Marking territory: Beavers will slap their tails to establish and defend their territory.
* Calling family members: Beavers can use the tail slap to call their family members together.
* mating signals: Beavers may slap their tails during mating rituals.
The flat, broad shape of a beaver's tail and the way it's positioned makes it an effective tool for creating this loud, distinctive sound.
