The feet and head are brown The melanistic form of the Eurasian red fox.Has blackish-brown or black skin with a light-brownish tint.The red fox (Vulpes vulpes) is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, being present across the entire Northern Hemisphere from the Arctic Circle to North Africa, North America and Eurasia. Its range has increased alongside human expansion, having been introduced to Australia, where it is considered harmful to native mammals and bird populations.
Red foxes are usually together in pairs or small groups consisting of families, such as a mated pair and their young, or a male with several females having kinship ties.
The young of the mated pair remain with their parents to assist in caring for new kits.
The remaining lower surface of the body is dark, brown or reddish.
The upper parts of the limbs are rusty reddish, while the paws are black.
Typically, albinism is accompanied by deformations and usually develops in years of insufficient food. The rump and lower back are dark brown or dark grey, with varying degrees of silver on the guard hairs.
The cross on the shoulders is black or brown, sometimes with light silvery fur.
Because of its widespread distribution and large population, the red fox is one of the most important furbearing animals harvested for the fur trade.
Too small to pose a threat to humans, it has extensively benefited from the presence of human habitation, and has successfully colonised many suburban and urban areas. vulpes by its smaller size, proportionately smaller skull and teeth, and coarser fur.
Gene mapping demonstrates that red foxes in North America have been isolated from their Old World counterparts for over 400,000 years, thus raising the possibility that speciation has occurred, and that the previous binomial name of Vulpes fulva may be valid. They have a stride of 25–35 cm (9.8–13.8 in) when walking at a normal pace.
In the far north, red fox fossils have been found in Sangamonian deposits in the Fairbanks District and Medicine Hat. North American red foxes are generally lightly built, with comparatively long bodies for their mass and have a high degree of sexual dimorphism.
Apart from its large size, the red fox is distinguished from other fox species by its ability to adapt quickly to new environments.
