The gerenuk does not drink water regularly. Other grazing animals include Beira, Dorcas gazelle, Soemmerring's Gazelle, gerenuk and the Beisa oryx. It is often confused with the gerenuk due to their striking resemblance. Large animals native to the park include Beisa oryx, Soemmering's gazelle, gerenuk and Grevy's zebra. In 1886, Franz Friedrich Kohl proposed a new genus for the gerenuk, "Litocranius". It preys on impala, Grant's gazelle, gerenuk, wildebeest, waterbuck, hare and guineafowl. The lesser kudu and the gerenuk might compete for evergreen species in the dry season. The gerenuk has a longer, heavier neck and a shorter tail. The gerenuk is a notably tall, slender antelope that resembles gazelles. The gerenuk may expose itself to rain, probably to cool its body.
