This is crucial for cutting through hard woods like maple and oak. A beaver's hind legs are longer than its front legs, thus making the rear end to be higher than the front end while walking.īeaver skulls and teeth are disproportionately large. The ears are short, round, and dark brown in coloration. The underhairs are much finer than the outer, protective, guard-hairs. They have a waterproof, rich, glossy, reddish brown or blackish brown coat. Habitat Regions: temperate terrestrial freshwaterĪquatic Biomes: lakes and ponds rivers and streamsīeavers are primarily aquatic animals, and the largest rodents in North America. To ensure adequate water depth surrounding the lodge, beavers dam streams with logs, branches, mud, and stones. The lake lodge is built on the shelving shores of lakes. The pond lodge is built either a short way back from the edge of the bank, or partly hanging over it, with the front wall built up from the bottom of the pond. The floor is blanketed with bark, grass, and wood chips. The room inside may measure 2.4 m (8 ft) wide and up to 1 m (3 ft) high.
Over the years, repair and elaboration leads to an increase in hut size. The lodge, itself, is an oven-shaped house of sticks, grass, and moss, woven together and plastered with mud.
One entrance opens up into the center of the hut floor, while the other is a more abrupt descent into the water. The island lodge consists of a central chamber, with its floor slightly above the water level, and with two entrances. Beavers live in lodges, of which there are three types: those built on islands, those built on the banks of ponds, and those built on the shores of lakes.
