Size and Appearance
- Beavers are the second-largest living rodents after capybaras, weighing up to 50 kg (110 lb).Â
- They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet, and flat, scaly tails.Â
- The North American beaver and Eurasian beaver are the two existing species. They differ in skull and tail shape and fur color.Â
Habitat and Behavior
- Beavers live in freshwater habitats like rivers, streams, lakes and ponds.Â
- They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges.Â
- Beavers build dams and lodges using tree branches, vegetation, rocks and mud. Dams restrict water flow, and lodges serve as shelters.Â
- They are mainly nocturnal and crepuscular, spending the daytime in their shelters.Â
- Beavers hold territories and mark them using scent mounds made of mud, debris, and castoreum.Â
Social Structure
- Beavers form monogamous pairs and usually live in family groups of up to 8 related individuals called colonies.Â
- The younger siblings stay with their parents for up to 2 years, helping with infant care, food collection, and dam building.Â
- Beaver families are territorial and defend against other families.Â
Adaptations
- Beavers have large skulls with powerful chewing muscles and four chisel-shaped incisors that continue to grow throughout their lives.Â
- Their eyes, ears and nostrils are arranged so that they can remain above water while the rest of the body is submerged.Â
- Beavers have closable nostrils and ears, and transparent nictitating membranes that cover their eyes underwater.Â
Conservation
- Before protections began in the 19th and early 20th centuries, overhunting had nearly exterminated both beaver species.Â
- Their populations have since rebounded, and they are listed as species of least concern by the IUCN Red List of mammals.Â
- Beavers are considered a keystone species as their infrastructure creates wetlands used by many other species.Â
