Canadian beaver

The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States.

Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.
