The red fox (Vulpes vulpes) is a mammal of the order Carnivora. It has the widest range of any terrestrial carnivore, being native to Canada, Alaska, most of the contiguous United States, Europe, North Africa and almost all of Asia. The red fox is found in a variety of biomes, from prairies and scrubland to forest latitudes but does venture considerably far north, competing directly with the Arctic fox on the tundra. The largest species within the genus Vulpes, the Red Fox may reach an adult weight of 6.5-24lbs (3-11kg), but this varies from region to region. The red fox is most commonly a rusty red, with white underbelly, black ear tips and legs, and a bushy tail usually with a distinctive white tip. The “red” tone can vary from dark chestnut to golden, and in fact can be “agouti”, with bands of red, brown, black and white on each individual hair. Fox eyes have vertical-slit pupils, similar to those of domestic cats.
