A zonkey is a cross between a zebra and a donkey. Donkeys are closely related to zebras, and both belong to the horse family. Zonkeys are very rare.
At Ark Encounter, Cletus is a zonkey—a cross between Grant’s zebra and a mammoth donkey.
Grant’s zebras, one at Ark Encounter, are the smallest of the six subspecies of plains zebras and the smallest zebra species overall. Are zebras black with white stripes or white with black stripes? It depends on how you look at it! While most zebras appear to have a white base coat with black striping, their skin is solid black.
