Beaver
The beaver (genus Castor) is a primarily nocturnal, large, semi-aquatic rodent. Castor includes two extant species, North American Beaver (Castor canadensis) (native to North America) and Eurasian Beaver (Castor fiber) (Eurasia). Beavers are known for building dams, canals, and lodges (homes). They are the second-largest rodent in the world (after the capybara).
Their colonies create one or more dams to provide still, deep water to
protect against predators, and to float food and building material. The
North American beaver population was once more than 60 million, but as
of 1988 was 6–12 million.
