Grévy's zebra
The Grévy's zebra is the largest of all wild equines. It is from head to tail with a tail, and stands high at the withers. These zebras weigh . Grévy's zebra differs from the other two zebras in its more primitive characteristics. It is particularly mule-like in appearance; the head is large, long, and narrow with elongated nostril openings; the ears are very large, rounded, and conical and the neck is short but thick. The zebra's muzzle is ash-grey to black in colour with the lips having whiskers. The mane is tall and erect; juveniles have a mane that extends to the length of the back and shortens as they reach adulthood.
Burchell's zebra
Like most plains zebras, females and males are relatively the same size, standing 1.1 to 1.4 meters (3.75 to 4.6 feet) at the shoulder. They weigh between 485 to 550 pounds. Year-round reproduction observed in this subspecies in Etosha National Park, Namibia, concludes synchronization of a time budget between males and females, possibly explaining the lack of sexual dimorphism.
