Is the silver fox a distinct species?

April 11, 2017 | Author: | Posted in Zoology

The silver fox is not a separate species. It is merely a phase of the red fox. The black fox, the platinum fox and the so-called cross fox also be­long to the red fox species.

Typical silver foxes have a silvery appearance, due to the white tips on many of the hairs. The bushy tail is black with the exception of a white tip. Black, silver and cross foxes are found in the northern part of North America and in Siberia. Totally black specimens of this species are seldom found except in the far north.

As a rule, the fur of the cross fox has a yellowish or orange tone with some silver points and dark cross markings on the shoulders. Pelts of silver foxes vary in color from black with a slight dusting of silver on the head and shoulders-to half black and half silver.

All these phases are rare in the wild state and it is believed that they are usually born in litters of normally red cubs. The platinum fox was bred from a silver fox sport.

Likewise the blue fox is a color phase of the Arctic or white fox, which varies in color from dull blue, bluish brown to pure white.
