Their horns are short and round with sharp pointed tips. An adult can grow to 90 cm (35 in) in length, 45 cm in height, and 20 kg (44 lb) in weight. Newborns appear darker because they are born with their stripes closer together. Zebra duikers have gold or red-brown coats with 12-16 distinctive zebra-like stripes, dark markings on their upper legs, and russet faces. The bay duiker and Jentink's duiker probably evolved during the Pleistocene, less than 2.5 million years ago. Similarly, Abbott's duiker and yellow-backed duiker form a clade sister to Sylvicapra. They showed that within the "giant duiker" group, the bay duiker formed a clade with Jentink's duiker, and the zebra duiker is sister to this clade. Johnston (of the University of Orleans) and colleagues constructed a cladogram of the subfamily Cephalophinae (duiker) based on mitochondrial analysis. However, the status of two species, the zebra duiker and the Aders' duiker, remained dubious. Ī 2001 phylogenetic study divided Cephalophus into three distinct lineages: the giant duikers, east African red duikers and west African red duikers. The zebra duiker is locally known as the marking deer in Liberia. The word "duiker" comes from the Afrikaans word duik, or Dutch duiker - both mean "diver". The specific name zebra pertains to the striking resemblance this duiker bears to the zebra due to the presence of dorsal stripes. The generic name probably comes from the combination of the New Latin word cephal, meaning head, and the Greek word lophos, meaning crest. It was first described by British zoologist John Edward Gray in 1838 in Annals of Natural History. The bay duiker is classified under the genus Cephalophus and the family Bovidae. The scientific name of the zebra duiker is Cephalophus zebra. Phylogenetic relationships of the bay duiker (Johnston et.al. ![]() It is believed to be one of the earliest duiker species to have evolved. They are sometimes referred to as the banded duiker or striped-back duiker. The zebra duiker ( Cephalophus zebra) is a small antelope found primarily in Liberia, as well as the Ivory Coast, Sierra Leone, and occasionally Guinea.
