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.
