Zebra duiker
Zebra duikers have gold or red-brown coats with 12-16 distinctive zebra-like stripes, dark markings on their upper legs, and russet faces. Newborns appear darker because they are born with their stripes closer together. An adult can grow to in length, 45 cm in height, and in weight. Their horns are short and round with sharp pointed tips. They are about 4.5 - 5.0 cm long in males, and half that in females. Female body size is larger than males, possibly due to long gestation periods.
Cape mountain zebra
The Cape mountain zebra is not territorial, and populations consist of small groups of two types: breeding groups and bachelor groups. A breeding herd consists of a mature stallion and up to five mares and their foals. Stallions that cannot obtain mares associate in less defined bachelor groups. Once established, breeding groups normally stay together for many years; one stallion in the Mountain Zebra National Park is known to have stayed with his herd for more than a decade until he was at least 17 years old. 
Foals leave their herds on their own accord at around 22 months of age, and unlike the Hartmann subspecies whose mares force foals out, stallions of the Cape subspecies actually try to prevent them leaving. This behaviour of foals in free-ranging populations could be a mechanism to prevent inbreeding.
