Leave it to Beaver


Beavers are herbivorous mammals weighing 16–35 kg and measuring up to 1.3 m from snout to paddled tail, the beaver (Castor canadensis) is Canada’s largest rodent and the second-largest rodent in the world (after the capybara). It is primarily nocturnal and lives a semi-aquatic life. One of the only mammals, other than humans, that can manufacture its own environment, the beaver is known for building dams, canals and lodges. Its colonies are created by one or more beaver-built dams, which provide still and deep water for protection against predators.

The beaver is an emblem of Canada older than the maple leaf; it has had a greater impact on Canadian history and exploration than any other animal or plant species.

Description

The thickset body of the beaver is covered with dark, reddish brown fur consisting of coarse guard hairs over dense, insulating under-fur. The large mass-to-surface ratio and the dense, insulating fur adapt it for a semi-aquatic existence in water that is often ice cold. Oil secreted by two glands near the anus is applied by the beaver to waterproof its fur. After swimming under water for six or seven minutes the beaver is not wet to the skin.
