The silver fox is a melanistic form of red fox (Vulpes vulpes). Silver foxes display a great deal of pelt variation: some are completely black except for a white coloration on the tip of the tail, some are bluish-grey, and some may have a cinereous color on the sides. Historically, silver foxes were among the most valued furbearers, and their skins were frequently worn by nobles in Russia, Western Europe, and China. Wild silver foxes do not naturally reproduce exclusively with members of the same coat morph, and can be littermates with the common red variety, though captive populations bred for their fur are almost exclusively mated with members of the same color.
