Beavers are powerful swimmers that can swim underwater for up to 15 minutes. As the beaver dips underwater, the nose and ears shut to keep water out. Transparent inner eyelids close over each eye to help the beaver see. Second only to humans, beavers alter their environment more than any other organism on the planet. These tireless animals always face challenges of predators and the full fury of the elements. They have thick fur, webbed feet and flattened, scale-covered tails. With powerful jaws and strong teeth, they chomp through trees to use the wood in order to build homes and dams, often changing their environment in ways few other animals can. In fact, the phrases “busy as a beaver” and “eager beaver” are synonymous with being industrious and hardworking. Beavers have large teeth and their upper incisors are range from 20 to 25 mm long, according to ADW, which is the Animal Diversity Web. They continue to grow throughout a beaver’s lifetime. Beavers have adapted to a semi-aquatic existence with closable nostrils and ears, and transparent eye membranes.
