Raccoons can be found across North America and the northern regions of South America. North American raccoons are the most common and most well-known type of raccoon. Medical College of Wisconsin.

Colorado and Gila River Valleys and adjoining territory from the delta north to northeastern Utah, and east to western Colorado and northwestern New Mexico. Raccoon eyes can appear after an injury or illness that causes tiny blood vessels to bleed into the skin under the eyes. They're not the same as the dark circles you get when you're tired. Those dark circles are much milder and aren't from a medical condition.In Spanish, the raccoon is called mapache, derived from the Nahuatl mapachtli of the Aztecs, meaning '[the] one who takes everything in its hands'. [14] Raccoons can live up to 16 years in the wild, though most do not make it through their second year. A raccoon that survives past its youth will live an average of five years. Primary causes of mortality include humans (hunting, trapping, cars) and malnutrition. [7] Species [ edit ]

Raccoons need only a permanent source of water, a den and an average amount of food. Dens tend to be hollow trees usually large and dry but they don’t add nesting material. Dens are typically made in maple or elm trees of 2-20 meters in size (Zelveloff 2002). They can also habit in attics and chimneys of abandoned farm houses or even occupied houses. Food is the least important part of equation to live. They also have the advantage to live in rural and urban areas, since they have adapted to survive in close proximity with humans (Hoffmeister 1989). Raccoons can live in the city or the wild. While not domesticated, they are—on rare occasion—kept as pets. Robinson, V.B., J. W. Newbeme, and D. M Brooks. 1957. Distemper in the American raccoon (Procyon lotor).

In the northern parts of their range, raccoons go into a winter rest, reducing their activity drastically as long as a permanent snow cover makes searching for food impossible. The symptoms of amyloidosis can vary drastically depending on where the protein is building up, and they can affect each person differently. Certain cancers Zelveloff, S.L. 2002.

Noises also have the ability to make raccoons immobile, therefore it is known as their protective sense (Zelveloff 2002).
