 Facts About Beavers

Beavers have thick waterproof fur, a flattened tail that serves as a rudder, closable nostrils and ears, as well as a transparent eye membrane, making them well-suited for a semi-aquatic lifestyle

One of the biggest rodents still alive is the beaver. They have flat, scale-covered tails, webbed feet, and thick hair. They cut down trees to build homes and dams using their strong jaws and teeth, frequently altering their surroundings in ways that few other creatures can. The expressions "busy as a beaver" and "eager beaver" actually refer to someone who is diligent and hardworking.

Size

The beaver comes in just two species. The average weight and length of an American beaver (Castor Canadensis) are 60 lbs. (27 kilograms) and 23 to 39 inches (60 to 100 cm), respectively. According to National Geographic, the tail increases the animal's length by 7.75 to 12 inches (20 to 30.5 cm).

The size of European beavers (Castor fiber) is comparable. According to the Animal Diversity Web (ADW) at the University of Michigan, they typically range in size from 29 to 77 lbs. (13 to 35 kg) and 29 to 53 in. (73 to 135 cm). Compared to American beavers, they have smaller skulls and slimmer tails.

The teeth of beavers are big. According to ADW, their upper incisors are between 20 and 25 mm long. They develop all the way through a beaver's life. Beavers' closable nostrils, ears, and translucent eye membranes have allowed them to adapt to a semi-aquatic lifestyle.

At the base of their tails, male and female beavers have a pair of scent glands known as castors. They employ the castoreum, a musk-like material secreted by these glands, to identify their territory.

Habitat

Beavers of all species need water to survive. They occupy freshwater ponds, lakes, rivers, marshes, and swamps, as well as areas nearby. American beavers are found all over North America, but they avoid deserts and Canada's most remote regions. Historically, Eurasian beavers inhabited all of Europe and Asia. Due to overhunting, they are now only found in tiny numbers in southern Scandinavia, Germany, France, Poland, and central Russia.

A lodge is a beaver's residence. Lodges are tiny, dome-shaped structures covered in mud and constructed with woven sticks, grasses, and moss. According to ADW, they have an interior that is up to 3 feet (1 m) high and up to 8 feet (2.4 m) broad. Lodges are constructed slightly above water level on islands, pond banks, or lake edges. Many resorts include an underwater entryway that provides quick access to the water.

Habit

Beavers are mainly nocturnal animals. They eat and build the most of the time. Beaver build dams to create ponds, which are their preferred habitat. When building a dam, branches are woven together, trees are felled using their teeth, and the structure is then waterproofed with mud. According to ADW, dams can be up to 6.5 feet (2 meters) height and several meters in length. In order to transport water from big bodies of water to their feeding location, beavers also create canals.

Ecosystems are significantly impacted by beavers. Dams can flood hundreds of acres and change the course of rivers. According to ADW, dams reduce erosion and elevate the water table, both of which contribute to water purification since silt accumulates and breaks down contaminants. Carbon levels rise and nitrogen levels fall as silt and trash accumulate. Invertebrates change type due to chemical changes, and new bird, fish, and amphibian species are drawn to the new water source. Flooded wood decays, transforming a forest into an ecosystem with open water. Abandoned dams deteriorate over time, and meadows develop. 

Diet

Beavers consume trees in addition to using them to create houses. Beavers can digest cellulose, which is a significant part of their food, unlike other mammals, according to ADW. Beavers consume the aspen, willow, maple, and poplar trees' leaves, roots, and bark. They consume aquatic plants as well.

Off spring

Beavers live in colonies and are extremely gregarious animals. A monogamous spouse, their offspring, and yearlings born the year before frequently reside in the same lodge.

Between January and March in the winter, beavers mate. The gestation period for the Eurasian beaver ranges from 60 to 128 days. Then, according to ADW, they give birth to one to six infants that range in weight from 8.1 to 22 ounces (230 to 630 grammes). Beaver cubs are known as kits. Typically, Eurasian kits are weaned six weeks after birth.

The gestation time for American beavers is between 105 and 107 days. One to four kits, weighing between 9 and 21 ounces, are born (250 to 600 g). American beavers often wean in two weeks or less.

The kits depart the lodge and build one of their own around the age of two. They locate a monogamous mate at the age of 3.

Classification/Taxonomy

According to the Integrated Taxonomic Information System (ITIS), the beaver has the following taxonomy:

Continent: Animalia Republic of Bilateria Deuterostomia infrakingdom Chapter: Chordata Vertebrata, a subphylum Gnathostomata, infraphylum Tetrapoda, the superclass Category: Mammalia Theria as a subclass Defining term: Eutheria Species: rodentia Castorimorpha, a suborder the Castoridae family Castor, genus Castor fiber, Castor canadensis (American beaver) (Eurasian beaver).

conservation status

Because beavers were previously prized for their pelts, castoreum, and meat, they were almost completely eradicated via hunting. Castoreum was a substance used in food, medicine, and perfumes, and beaver hats were once the height of fashion.

The International Union for Conservation of Nature (IUCN) no longer classifies beavers as endangered. They are widely distributed, frequent throughout much of their habitat, and their populations are steady.

Other Facts

After birth, American beaver kits can swim.

Beavers are built for life in the water. At 5 mph, their webbed feel and rudder-like tail help them move through the water (8 kph). Additionally, they can submerge themselves for up to 15 minutes at a time, according to National Geographic.

They use their tails for more than just swimming. Beavers also slap the water with them as they dive away from danger to frighten predators.

They don't hibernate, beavers. The entire winter, they keep eating and growing.

The pope authorised the consumption of beaver during Catholic fasting days in the 16th century because of its scaly tail and semi-aquatic existence, according to ADW.

According to a review in the International Journal of Toxicology, castor extract has been used as a flavoring component in food for at least 80 years. The Food and Drug Administration has deemed castoreum extract to be generally safe (GRAS). The use of castoreum in food products is uncommon, and its consumption is low — only about 292 lbs. (132 kg) a year, according to "Fenaroli's Handbook of Flavor Ingredients(opens in new tab)" — because it is difficult to gather and other flavor enhancers are easier to come by (CRC Press, 2004).
