Animal You | Raccoon | The body weight of an adult raccoon with an important habitat, so that the raccoon mammals of different sizes. Smaller specimens are found in South Florida, while near the northern limit of the range Raccoon more likely (see Bergmann rule). Males are usually 15 to 20% heavier than females. The largest recorded wild raccoon weighed 28.4 kg (62.6 lb) and 140 cm (55 inches) were recorded with a total length of far larger for procyonid. The physical characteristic of the raccoon is the area of black fur around the eyes, the color contrasts sharply with the surrounding white face. The dark mask may also reduce glare and improve night vision. As raccoons have short legs compared to their compact torso, they are generally not able to either run fast or jump great distances. Raccoons can with an average speed of about 5 kmh swimming (3 mph) and water to stay for a few hours. Climbing a tree for about an unusual ability for a mammal the size of a raccoon rotates its hind legs, so they are suitable for the rear. Raccoons have a dual cooling system temperature, so they are able to sweat and pant for heat dissipation to organize.
Raccoon skulls have a short and wide face area and a large skull. Males penis bones bent about 10 cm (4 inches) long and hard before. Few studies have been conducted on the mental abilities of raccoons, most of them on the animal to determine touch. In a study of scientific behavior HB Davis in 1908, raccoons were 11 of 13 locks complex to open in less than 10 attempts and had arranged no problem repeating the action when the locks were new or versa vice versa. Studies have focused, in 1963, 1973, 1975 and 1992 have shown their memory raccoon solving tasks remember three years. In a study by B. Pohl in 1992, raccoons were able to instantly differentiate between identical and different symbols three years after the short learning curve. Stanislas Dehaene reports in his book The Number Sense raccoons boxes containing two or four grapes from these three raccoons can usually distinguish degree in a delay caused by the increasing daylight between late January and mid-March. For example, while raccoons extent in the southern states generally later than average, the mating season in Manitoba also capped peaks later than usual in March and June.
The weaker members of a male social group also felt that the opportunity to mate, since the stronger can not mate with all available females. The average litter size varies widely with habitat, 2.5 to 4.8, Alabama, North Dakota. (also called "boys") are blind and deaf at birth, but their mask is already visible against their light fur. The birth weight of about 10 cm (4 inches) long kits 60-75 g (2.1 to 2.6 ounces). While many women near the beach home of their mother, males can sometimes move more than 20 km (12 miles). This is considered an instinctive behavior, preventing inbreeding. However, mother and child share a cave in the first winter in cold regions. Even if they have thrived in sparsely wooded areas in the last decades, raccoons depend on vertical structures to climb when they feel threatened. ree cavities in old oaks and other trees and rock crevices are preferred as sleeping places raccoons, winter and litter. If such dens are unavailable or access is not practical, raccoons use burrows other mammals, dense vegetation or tree crotch.
Since amphibians, crustaceans and other animals along the shores of lakes and rivers, an important part of the diet raccoon, deciduous plain or mixed with abundant water and marshes sustain the population density highest. While population densities range from 0.5 to 3.2 animals per square kilometer (1.3 to 8.3 animals per square mile) in prairies and do not usually exceed 6 animals per square kilometer (15.5 animals per square mile) in upland hardwood forests, more than 20 raccoons per square kilometer (51.8 animals per square mile) live in lowland forests and marshes. Raccoons can carry rabies, a deadly disease carried by the neurotropic rabies virus in saliva and transmitted by bites caused. Reported by the 6940 confirmed cases of rabies in the United States in 2006, there were 2615 (37.7%) in raccoons. One human death has been reported after transmission of the rabies virus from a raccoon. One of the main symptoms of rabies in raccoons are generally sickly appearance, impaired mobility, abnormal vocalization, and aggressiveness.
ince healthy animals, especially nursing mothers, sometimes daylight daytime activity in search of food. Not a reliable indicator of illness in raccoons Unlike rabies and made at least a dozen other pathogens by Raccoons distemper is a viral disease does not affect humans. This disease is the most common cause of natural death in the North American population raccoon and people of all ages. For example, 94 of 145 raccoons died during an outbreak in Clifton, Ohio, in 1968. Some of the major bacterial diseases which affect raccoons leptospirosis, listeriosis, tetanus, and tularemia. Although internal parasites weaken their immune system can help many people well fed nematodes in the digestive tract without symptoms.
