"Zorro" means "fox." But these creatures, found only in South America, resemble coyotes as much as they do any fox.

The ears of bat-eared foxes can grow up to 5.3 inches long. For an animal that stands 11.8-15.7 inches at the shoulder, that’s enormous.

The slender bodies of red foxes are designed for speed and agility. They can be found in almost the entire northern hemisphere, in part because of their diverse diet.
