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 reticulated giraffe (Giraffa reticulata [3] or Giraffa camelopardalis reticulata [4]) is a species/subspecies of giraffe native to the Horn of Africa.It is differentiated from other types of giraffe by its coat, which consists of large, polygonal (or squared), block-like spots, which extend onto the lower legs, tail and face.
Strips cut from the striped part of the skin of an okapi, sent home by Sir Harry Johnston, were the first evidence of the okapi's existence to reach Europe.. Although the okapi was unknown to the Western world until the 20th century, it may have been depicted since the early fifth century BCE on the façade of the Apadana at Persepolis, a gift from the Ethiopian procession to the Achaemenid ...
As a result of their towering height, giraffes spend most of their days grazing amongst the canopies of acacia trees. Our giraffe unit plan takes students on an All About Giraffes: A 5-Day Lesson Plan
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).
However, recent genetic research has shown that the populations from northern Cameroon and southern Chad actually are the Kordofan giraffe (G. c. antiquorum). [5] Therefore, the giraffes that remain in Waza National Park (Cameroon) belong to the Kordofan giraffe, while the only remaining viable population of the West African giraffe is in Niger ...

The extinct giraffid Samotherium (middle) in comparison with the okapi (below) and giraffe. The anatomy of Samotherium appears to have shown a transition to a giraffe-like neck. [9] Giraffids like Palaeotragus, Shansitherium and Samotherium appeared 14 mya and lived throughout Africa and Eurasia. These animals had broader skulls with reduced ...
