Despite being widespread in some beaver-inhabited areas, beaver canals and their environmental effects are much less studied than beaver dams. Beaver primarily develop canals to increase accessibility of river resources, facilitate transport of acquired resources, and to decrease the risk of predation.
Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as ...
Where modern beavers have square chisel shaped teeth, Dipoides teeth were rounded. However an excavation of a site that was once a marsh, in Ellesmere Island, showed signs that they dined on bark and young trees, like modern beavers. The excavation seemed to show that, like modern beavers, Dipoides dammed streams. [3]
Beavers are associated with activity and environmental engineering. If you are “as busy as a beaver,” you are getting things done. These aquatic rodents spend most of their time in the water ...
Trogontherium cuvieri grew larger than living beavers , with a skull up to 21 centimetres (8.3 in) in length, but was smaller than Castoroides. The incisors are covered in fine longitudinal grooves, and have a convex enamel face. The cheek teeth are high crowned. The sagittal suture of the skull is flanked by two deep depressions.
In downtown Martinez, California, a male and female beaver arrived in Alhambra Creek in 2006.

Castoroides (from Latin castor (beaver) and -oides (like) [2]), or the giant beaver, is an extinct genus of enormous, bear-sized beavers that lived in North America during the Pleistocene. Two species are currently recognized, C. dilophidus in the Southeastern United States and C. ohioensis in most of North America.
