The sleek coat is patterned with black and white vertical stripes that are much narrower than those of the plains zebra Equus burchelli and persist until above the hind legs where a chevron pattern occurs 6. The horizontal stripes on the legs remain distinct all the way down to the hooves, and the tall, upright mane is also striped in a pattern that continues on from the neck.

A wide black stripe along the back is very distinctive and is bordered by white on the rump. Within a single population around ten percent of the mature stallions will occupy territories from which they have sole access to receptive females, although other males are still tolerated within the area, provided females are not in oestrus 2. These territories are patrolled and marked with dung and are the largest of any living herbivoreat up to ten square kilometres 2.

Territorial males also vocalise loudly to assert their dominance within the territory 7. Mares become sexually mature at three to four years and give birth to a single foal after a gestation period of 13 months every couple of years 2.

Foals are able to stand after a mere six minutes and can run after 45 minutes 6. Recent research has suggested, however, that they may serve a social function and may stimulate grooming 5. It is believed that the equine ancestor of horses, asses and zebras was striped, but these have subsequently been lost during the evolution of the other two groups 5. It has not been sighted in Somalia since and is therefore presumed extinct in this country 4.

Habitat loss presents a major threat to the long-term survival of the species as grasslands and water sources have significantly declined due to unplanned grazing by livestock. In addition, there has been a significant, very recent decline in the species in northern Kenya due to disease and drought 7. It is protected by law in Ethiopia and by a hunting ban in Kenya 1. This rare species also occurs mostly outside protected areas in communally-owned land and ranches where livestock-keeping is the principal livelihood 7.

Kenya is currently implementing a five-year conservation strategy for the species through a coalition of conservation organisations dedicated to protecting the species 7. James Warwick james jameswarwick.
