The raccoon is a forest animal, especially near rivers, although it has also learned to live in inhabited areas. In its natural habitat, it eats everything from frogs to fruits, but in cities and suburbs it uses trash containers to eat the remains of food thrown in them. Raccoons are nocturnal, have a keen sense of smell and are good climbers, Compared to most carnivorous mammals, they are very skilled with their front paws, which they use to grab and hold food. The raccoon is sometimes called a washing bear because of the habit of handling food, for example, skinning frogs, at the water's edge, which makes it appear that it washes them. He does this because certain kinds of frogs inflate his body and secrete a poison through his skin so as not to be ingested, which the raccoon eliminates by "washing" its food before eating it.
