The Silver Fox is a melanistic (meaning darker in color) form of red fox. Silver foxes display a great deal of pelt variation: some are completely black, save for the white tail tip, while others are bluish-grey, and others 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 and other parts of Europe, as well as in China.
Wild silver foxes do not reproduce exclusively with members of the same coat morph, and so there can be littermates with the common red variety. Captive populations of silver fox are typically bred for their fur are almost exclusively mated with members of the same color.
