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.
Cape mountain zebra
The Cape mountain zebra is a graminivore, meaning that its diet consists mainly of grasses. It is a highly selective feeder, showing a preference for greener leafy plants, particularly the South African red grass and the weeping lovegrass. Low growing, very course, small stalky grasses, as well as dying leaf material are usually avoided. 
It has been seen that the Cape subspecies is a climax grazer, meaning it feeds at quite a high level off the ground. This means that increasing the abundance of low level grazers such as springbok will reduce grass height to a level lower than the zebra’s biting height, which could have detrimental consequences to the population.
