Hartmann's zebras have broad black stripes with an off-white, creamy color between them. The black stripes on the animals' sides do not meet on the belly. The leg stripes extend horizontally, all the way down to the top of the hooves. These leg stripes can be thin and wrap around the entire leg. The stripe that covers the spine and top portion of the tail is said to be "zipper-like" in appearance. The most characteristic and interesting feature of both mountain zebra subspecies is a square flap of skin on the throat just below the head. This flap of skin, or dewlap, is larger on the males.
The average adult height at the shoulder is 120 - 130 cm or 4 - 4.3 ft. and the tail length is 50 cm or 20 in. The body length is 220 cm or 7.3 ft. The weight is 260 - 370 kg or 572 - 814 lb. There is no significant size difference between the sexes except the stallions are usually heavier.
Foals weigh about 25 kg or 55 pounds at birth. The foals' white stripes are more brown in color than white. As a foal matures the stripes become white. Foals nurse for as long as 7 months. They are capable of grazing when they are 2 weeks old. Like many zebras the foal can stand on its feet within an hour after its birth and can run with the herd after a few hours. This adaptation gives zebra foals a much better chance of escaping from predators. Both male and female Hartmann's mountain zebras sexually mature after two years.
