Dam Fun Facts About Beavers

SciShow shares fun facts about we are nature’s greatest engineers. Hell yeah we’re the greatest, we’re also the funniest!

Beavers go through all the trouble of dam-building primarily for defense…By surrounding themselves with deep water, beavers can protect their dens from predators like wolves and wild cats, while creating a habitat that supports the aquatic plants they like most, like cattails, willows, pondweed and aspen…Research has shown that little gaps intentionally created in a beaver dam will cause the members of a colony to drop everything to repair it, regardless of whatever else needs to be done. Scientists — a little evil — have even played audio recordings of running water near beaver sites, and have returned in the morning to find the speakers covered with sticks and mud.
