The trade distinguishes between mainland gray foxes depending on their origin: the Eastern one (Colorado, Missouri, Texas, Rocky Mountains etc.) with short-haired silky fur, silvery back, rusty yellow dewlap and the Western one (New York State, Pennsylvania, Virginia, Georgia, etc.) with full (“heavy”) hair, blackish-gray back and up to copper red dewlap.

Males have much larger horns than the females. Hair can range from dense (the densest hair in young calves) to sparse. The color of these rhinos is reddish brown.

Hyenas are known to have preyed on humans in prehistory: human hair has been found in fossilized hyena dung dating back 195,000 to 257,000 years.
