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.
Zebra
Zebras evolved among the Old World horses within the last 4 million years. It has been suggested that zebras are paraphyletic and that striped equids evolved more than once. Extensive stripes are posited to have been of little use to equids that live in low densities in deserts (like asses and some horses) or ones that live in colder climates with shaggy coats and annual shading (like some horses). However, molecular evidence supports zebras as a monophyletic lineage. The zebra has between 32 and 46 chromosomes, depending on the species.
