What is the African antelope whose male of the species have lyre-shaped horns?
Antelope hornless females (e.g. sitatunga, red lechwe, and suni). In some species, the males and females have differently coloured pelages (e.g. blackbuck and nyala). The size and shape of antelope horns varies greatly. Those of the duikers and dwarf antelopes tend to be simple "spikes", but differ in the angle to the head from backward curved and backward pointing (e.g. yellow-backed duiker) to straight and upright (e.g. steenbok). Other groups have twisted (e.g. common eland), spiral (e.g. greater kudu), "recurved" (e.g. the reedbucks), lyrate (e.g. impala), or long, curved (e.g. the oryxes) horns. Horns are not shed and their bony cores
Bongo (antelope) have two heavy and slightly spiralled horns that slope over their backs, and like many other antelope species, both male and female bongos have horns. Bongos are the only tragelaphids in which both sexes have horns. The horns of bongos are in the form of a lyre and bear a resemblance to those of the related antelope species of nyalas, sitatungas, bushbucks, kudus and elands. Unlike deer, which have branched antlers shed annually, bongos and other antelopes have pointed horns they keep throughout their lives. Males have massive backswept horns, while females have smaller, thinner, and more parallel horns. The
