Cross fox (animal)
The cross fox is a partially melanistic colour variant of the red fox (Vulpes vulpes) which has a long dark stripe running down its back, intersecting another stripe to form a cross over the shoulders. It tends to be more abundant in northern regions, and is rarer than the common red form, but is more common than the even darker silver fox.
