A zebroid (also zebra mule and zebrule) is the offspring of any cross between a zebra and any other equine: essentially, a zebra hybrid. In most cases, the sire is a zebra stallion. Offspring of a donkey sire and zebra mare, called a zebra hinny, do exist but are rare. Zebroids have been bred since the 19th century.The zebroid showed in the picture above, Eclyse, is a very unusual one, because of her coloring. With her über distinct makings, it's really hard not think she's a Photoshop mock-up.
