There are only two species of beaver. The American beaver (Castor canadensis) typically weighs 60 lbs. (27 kilograms) and are 23 to 39 inches (60 to 100 centimeters) long. The tail adds another 7.75 to 12 inches (20 to 30.5 cm) to its length, according to National Geographic. Eurasian beavers (Castor fiber) are around the same size. They usually we...
All beavers need water to survive. They live in or around freshwater ponds, lakes, rivers, marshes and swamps. American beavers live throughout North America, but stay clear of deserts and the far northern areas of Canada. Eurasian beavers once lived all over Europe and Asia. Now, they only live in small numbers throughout southern Scandinavia, Ger...
Beavers are primarily nocturnal. They spend most of their time eating and building. Beaver create dams to make ponds, their favorite place to live. Dams are created by weaving branches together, felling trees by cutting them down with their teeth, and waterproofing the construction with mud. Dams can be several meters in length and up to 6.5 feet (...
Beavers don’t just build homes from trees, they also eat them. Unlike other mammals, beavers can digest cellulose, which is a major component of their diet, according to ADW. Beavers eat leaves, roots and bark from aspens, willows, maples and poplar trees. They also eat aquatic plants.
Beavers are very social and live in groups called colonies. One lodge is often the home for a monogamous couple, their young and the yearlings born the year before. Beavers mate during the winter, from January to March. The Eurasian beaver has a gestation period of around 60 to 128 days. Then, they give birth to one to six babies that weigh around ...

Beavers were once hunted almost to extinction because they were valued for their pelts, castoreum and meat. Beaver hats were once the height of fashion, and castoreum was used in medicine, food and perfumes. Today, according to the International Union for Conservation of Nature(IUCN), beavers are not considered endangered. They are widespread, comm...
American beaver kits can swim 24 hours after birth. Beavers have bodies that are made for the water. Their rudder-like tail and webbed feel propel them through the water at 5 mph (8 kph). They can also stay under water for around 15 minutes at a time, according to National Geographic. Their tails aren’t just used for swimming. Beavers also slap the...
Beavers live for 10 to 12 years on average, while the longest-living beaver lived for 30 years. Their life expectancy is influenced by predators, food availability, and diseases. Beavers are the largest rodents in North America, and their lifespan reflects that fact.
The head-and-body length of adult North American beavers is 74–90 cm (29–35 in), with the tail adding a further 20–35 cm (7.9–13.8 in). Very old individuals can exceptionally exceed normal sizes, weighing more than 40 kg (88 lb) or even as much as 50 kg (110 lb) (higher than the maximum known for the Eurasian beaver).
In the absence of solar "cues," a beaver's activity is not synchronized with the solar day. The circadian rhythm, or regular day cycle, breaks down, and beaver "days" become longer, varying in length from 26 to 29 hours. At the Zoo, beavers usually wake up in the early evening, around 4 p.m.
Many populations of Eurasian beaver do not make rafts, but forage on land during winter. Beavers usually live up to 10 years. Felids, canids, and bears may prey upon them. Beavers are protected from predators when in their lodges, and prefer to stay near water.
