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.
Giraffe (Giraffa camelopardalis) The giraffe is a large ruminant native to sub-Saharan Africa. [30] It is the tallest terrestrial animal and has an extremely long neck and legs. The neck can grow up to 2.4 m (7 ft 10 in). [31] Male and female giraffes both have horn-like structures called ossicones, which in males can reach 13.5 cm (5.3 in). [32]
Male okapis have short, hair-covered horn-like structures called ossicones, less than 15 cm (5.9 in) in length, which are similar in form and function to the ossicones of a giraffe. [26] The okapi exhibits sexual dimorphism , with females 4.2 cm (1.7 in) taller on average, slightly redder, and lacking prominent ossicones, instead possessing ...

The four giraffes at Potawatomi Zoo have been a top attraction the past couple of years. Now a female is joining with the hope for breeding.
However, as they get older, males become more solitary but may also associate in pairs or with female groups. [94] [98] Giraffes are not territorial, [17] but they have home ranges that vary according to rainfall and proximity to human settlements. [99] Male giraffes occasionally roam far from areas that they normally frequent. [32]: 329
During the Pleistocene epoch, about 11 other antilocaprid species existed in North America, many with long or spectacularly-twisted horns. [8] Three other genera (Capromeryx, [9] [10] Stockoceros [11] [12] and Tetrameryx [13]) existed when humans entered North America but are now extinct. The pronghorn's closest living relatives are the giraffe ...
