Male okapi displaying his striking horizontal stripes. The okapi is a medium-sized giraffid, standing 1.5 m (4 ft 11 in) tall at the shoulder. Its average body length is about 2.5 m (8 ft 2 in) and its weight ranges from 200 to 350 kg (440 to 770 lb). [25] It has a long neck, and large and flexible ears.
It is the tallest living terrestrial animal and the largest ruminant on Earth. The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its spotted coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi.

The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
The pronghorn's closest living relatives are the giraffe and okapi. [14] The Antilocaprids are part of the infraorder Pecora, making them distant relatives of deer, bovids, and moschids. The pronghorn is the fastest land mammal in the Americas, with running speeds of up to 88.5 km/h (55 mph). It is the symbol of the American Society of ...
Totaling 42 to 44 teeth, this dentition is closer to that of equids, which may differ by one less canine, than their other perissodactyl relatives, rhinoceroses. [ 27 ] [ 28 ] Their incisors are chisel-shaped, with the third large, conical upper incisor separated by a short gap from the considerably smaller canine.
The reasons Paraceratherium and its relatives became extinct after surviving for about 11 million years are unknown, but it is unlikely that there was a single cause. Theories include that their large size was related to the now outdated concept of inadaptive evolution , climate change , vegetational change, and low reproduction rate .
The closest living relative to both giraffes and okapi outside of Africa is the North American pronghorn (Antilocapra americana) of the Antilocapridae, in which it is the sole extant species. Additionally, deer ( Cervidae ) are distantly related to giraffes, okapi and pronghorn, as they are also classed within the infraorder Pecora.
