Description

Beavers are the largest rodents in North America and the second largest in the world. 

Beavers have orange teeth that grow continuously throughout their lives. The orange color comes from an iron-rich enamel coating. 

Beavers are powerful swimmers that can hold their breath for up to 15 minutes. They shut their nose and ears when they go underwater. 

Beavers build dams to create ponds that protect them from predators. The largest beaver dam is in Wood Buffalo National Park in Canada. 

Beavers are semiaquatic rodents that thrive around water. They build dams to create suitable habitats.
