In appearance, zonkeys generally resemble donkeys more than zebras, with large heads and ears. They are brown, tan, or grey in color with a lighter underside. Their stripes are most visible on their legs and belly.

Zonkeys are found in African savannas and woodlands, where zebras and donkeys naturally cohabitate. Many zonkeys are found in zoos, where they are generally bred deliberately.
