Beavers can breath underwater?

Did you know that beaver can hold their breaths for 45mins under water? beavers are known as animal engineer the busy little animals chewing down trees with their big teeth, building dams, and hauling mud and their babies on their paddle-like tails. When you think of beavers, do you think of real animals or do you think of a cartoon or advertising image? Because there are so many images of beavers in the media, the real animal can easily be confused with the stereotype. In the case of the beaver, the scientific facts are far more interesting than the simple image of our popular culture. Beavers are nocturnal herbivores, which means they eat plants at night. As green plants become available in the spring and summer, beavers eat fresh buds, greens, grass, leaves and aquatic plants. When beavers cut cottonwood and willow trees during the fall, their activity is most visible. Because beavers don't hibernate they must store food for winter, either as fat on their bodies or in a food cache. Trees are trimmed, cut into convenient sizes, and carried to the dam site. There, beavers either eat the bark, turning branches in their forefeet as humans eat an ear of corn, or store them in underwater food piles near the lodge so that they can get to them easily even when the beaver pond is frozen over. Beavers eat the bark and cambium layer, of each limb. The survival of a beaver colony depends on the availability of this under-ice food supply The beaver lodge is built in standing water of lakes, ponds or marshes. It consists of limbs and logs plastered with mud and sod. The inner chamber always has an air vent and is lined with grasses or shredded bark to absorb moisture. Entrances are underwater. The chief construction materials of aspen, willow, cottonwood, and maple are also preferred foods. Beavers are protected from predators, such as coyotes, dogs, bobcats, and mountain lions by their aquatic habits. When disturbed they will slap their tails on the water surface to warn the colony of danger and then dive to deep water. They can stay submerged at least 25 minutes, but most dives last 1 to 2 minutes. Beaver populations are affected by drought and floods more than by predators. Human activities exert the greatest effect on beaver populations. some says that they can only stay underwater for only 15mins. how long they breath under water is not an issue as long as they can breath underwater for that long is something amazing to know :) mind feed solved...
