浣熊
- There have been cases where American raccoons lived up to 22 years, exceeding their average lifespan in captivity.
- It jumps from 10–12 m without injury.
- It can open complex locks and remember the solution for years.
- The common raccoon is curious and explores everything, especially places where food can be hidden. It is interested in the contents of anything that can hold food.
- The raccoon's paws are short, with highly developed fingers that make the footprints resemble a human palm print. This helps it climb skillfully and grasp food.
- The common raccoon has adapted well in Europe and quickly spread throughout Germany, France, and even southern Russia. It was introduced to Europe in the 1930s.
- The American raccoon was called "genet's fur," as the animal strongly resembled the genet—a predator of the viverridae family.
- In nature, birds are natural prey for the American raccoon. Raccoons should absolutely not be kept at home with birds.
- The raccoon “washes” food not for cleanliness — wet paws become more sensitive and allow it to “see” the object by touch.
- The forepaws occupy a disproportionately large part of the sensory cortex.
年龄
Common raccoons typically live from 12 to 18 years, with a maximum lifespan of 21 years, and a theoretical lifespan ranging from 10 years and 6 months to 21 years. The age of sexual maturity occurs between 9 months and 1 week and 1 year and 3 months. The young’s eyes open between 2 weeks and 4 days and 3 weeks and 3 days; during the embryonic stage, the embryo develops in the mother's womb. The young are born blind and hairless, drink their mother’s milk, and grow rapidly during the infant stage, which lasts from 1 day to 2 months and 1 week. Following this, the young after rapid growth leaves the den, learns to find food, and lives independently for a period lasting from 2 months and 2 weeks to 1 year. An adult raccoon is ready to reproduce and lives independently during the adult stage, which lasts from 1 to 20 years.
表型
The young raccoon’s eyes open during the third week of life; the species has a tail with rings which aids in balance when climbing, and the tail also serves as a signal to other raccoons. The northern raccoon possesses dense fur that protects against cold and rain, and a black mask around the eyes helps conceal the animal at night while safeguarding its vision. The adult common raccoon has four front paws that are highly sensitive and dexterous, and it uses them in place of hands. The striped tail assists with balance for the species.
生理学
Common raccoons measure between 60 and 65 centimeters in height and between 55 and 75 centimeters in length, with a mass ranging from 5.94 to 6.51 kilograms; the species exhibits significant developmental changes across its life stages, beginning with the "Embryo" stage where individuals have a body mass from 1 to 80 grams and a body length from 1 millimeter to 4 centimeters; in the "Infant" stage, the young weigh from 80 grams to 1.2 kilograms and measure between 12 and 35 centimeters in length; following rapid growth, the "Juvenile after rapid growth" stage sees individuals with a body mass from 1.2 to 5 kilograms and a body length from 35 to 65 centimeters; finally, adult common raccoons possess a body mass ranging from 5 to 14 kilograms and measure between 60 and 75 centimeters in length.
栖息地
Common raccoons inhabit land, terrestrial forests, and terrestrial grassy areas, including elevations up to 2 kilometers above sea level. The species lives in temperate mixed forests with warm summers containing many oak, birch, and maple trees, as well as flooded meadows with abundant grass where water frequently covers the ground. The climate varies; it can be consistently hot and humid year-round with nearly daily rain, including very hot summers exceeding 25 to 30 degrees Celsius, or it can feature numerous rains, a cool summer, and snow in winter. The species also experiences winters with significant snowfall and cold temperatures.
庇护所
Common raccoons are found near water or in urban environments and utilize dens for sleeping, breeding, resting, and protection from the sun. The species constructs their dens using branches, berries, and grass.
地理
Common raccoons inhabit the Nearctic, Neotropical, and Palearctic biogeographical realms. The species occupies lowland forests of the Eastern Great Lakes, Wasatch and Uinta mountain forests, forests of New England and Acadia, and the transition zone between eastern Canadian forests and the boreal zone.
食性
The common raccoon eats a wide variety of food, including insects and frogs, as well as collecting fruits and berries, raiding nests, and frequently searching through garbage bins; it seizes food with its front paws and often washes it in water before eating. The species’ diet consists of insects, fruits, berries, frogs, fish, small mammals, garbage, toads, decaying organic matter, and fruits. The young consume milk, while the daily food requirement ranges from 150 grams to 400 grams. The common raccoon preys on American bullfrogs, white-footed prairie dogs, gray voles, gallinules, mallard ducks, American rabbits, and blackbirds. Predators of the species include alligators, true crocodiles, and pumas.
繁殖
Common raccoons inhabit terrestrial environments and develop on land, away from bodies of water; nests can be found in shrubs or trees, high in branches, on the ground surface, or near rivers, lakes, ponds, or marshes. The male and female mate at the end of winter, and after a gestation period of 2 months, the female gives birth to 2–7 live young. The young are raised in nests built on the ground or close to it, or high in the branches of shrubs or trees, where only the mother demonstrates parental care. A litter consists of 2–7 individuals. The species reproduces through sexual reproduction involving fertilization, without generational changes. The female has a reproductive interval of 1 year and produces 2–7 litters. Young raccoons reach maturity from 10 months to 1 year and 1 month.
