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.
The vertebral transverse processes of mammals are homologous to the cervical ribs of other amniotes. [citation needed] Most mammals have seven cervical vertebrae, with the only three known exceptions being the manatee with six, the two-toed sloth with five or six, and the three-toed sloth with nine.

The Okapi Wildlife Reserve (French: Réserve de faune à okapis) is a wildlife reserve in the Ituri Forest in the north-east of the Democratic Republic of the Congo, near the borders with South Sudan and Uganda. [3] At approximately 14,000 km 2, it covers approximately one-fifth of the area of the forest.
In okapi, the male's ossicones are smaller in proportion to the head, and taper towards their tips, forming a sharper point than the comparatively blunt giraffe ossicone. Whereas female giraffes have reduced ossicones, female okapi lack ossicones entirely. The morphology of ossicones in the extinct relatives of giraffes and okapi varies widely.
The Okapi Wildlife Reserve – an area 13,700 square kilometers, about one-fifth of the Ituri Forest – was created with the help of the Okapi Wildlife Project in 1992. The project continues to support the reserve by training and equipping wildlife guards and by providing assistance to improve the lives of neighboring communities. [1]
The diagram shows that both giraffes and okapi have 7 cervical vertebrae. Almost all mammals -- including humans -- have 7 cervical vertebrae.

The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.
The thoracic vertebrae number between five and ten, and the first thoracic vertebra is distinguishable due to the fusion of its attached rib to the sternum while the ribs of cervical vertebrae are free. [7] Anterior thoracic vertebrae are fused in many birds and articulate with the notarium of the pectoral girdle. [13]
