The raccoon (Procyon lotor), sometimes called the common raccoon to distinguish it from other raccoon species is one of the most well-known North American mammals.
Head to hindquarters, raccoons measure between 40 and 70 cm (16 and 28 in), not including the bushy tail which can measure between 20 and 40 cm (8 and 16 in), but is usually not much longer than 25 cm (10 in). The shoulder height is between 23 and 30 cm (9 and 12 in). The body weight of an adult raccoon varies considerably with habitat, making the raccoon one of the most variably sized mammals. It can range from 5 to 26 kilograms (10 to 60 lb), but is usually between 5 and 12 kilograms (10 and 30 lb). The smallest specimens live in southern Florida, while those near the northern limits of the raccoon's range tend to be the largest (see Bergmann's rule). Males are usually 15 to 20% heavier than females. At the beginning of winter, a raccoon can weigh twice as much as in spring because of fat storage. The largest recorded wild raccoon weighed 28.4 kg (62.6 lb) and measured 140 cm (55 in) in total length, by far the largest size recorded for a procyonid.
