Litocranius walleri (Brooke, 1878) is a bovid commonly called the gerenuk. It is a medium-sized antelope closely related to gazelles and springbok, but unlike these it has low-crowned teeth. L. walleri is the only species in the genus Litocranius. It is commonly found in dry thornbush savannah in northeastern Africa, where it feeds almost exclusively on thorny shrubs and trees while frequently using a bipedal stance. L. walleri is classified as “Near Threatened” (NT) by the International Union for Conservation of Nature and Natural Resources (IUCN) because its population trends are decreasing.
