The Red Fox (Vulpes vulpes) is a mammal of the order carnivora. In Great Britain and Ireland, where there are no longer any other native wild canids, it is referred to simply as the "Fox". It has the widest range of any terrestrial carnivore, being native to Canada, Alaska, almost all of the contiguous United States, Europe, North Africa and almost all of Asia, including Japan. It was introduced in Australia in the 19th century. As its name suggests, its fur is predominantly reddish-brown, but there is a naturally occurring grey morph known as the Silver Fox; a strain of tame Silver Fox has been produced from these animals by systematic domestication.
