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 coat patterns of modern giraffes may also have coincided with these habitat changes. Asian giraffes are hypothesised to have had more okapi-like colourations. [6] The giraffe genome is around 2.9 billion base pairs in length, compared to the 3.3 billion base pairs of the okapi. Of the proteins in giraffe and okapi genes, 19.4% are identical.
Often mistaken with the southern giraffe, the northern giraffe differs by the shape and size of the two distinctive horn-like protuberances known as ossicones on its forehead; they are longer and larger than those of southern giraffe. Male northern giraffes have a third cylindrical ossicone in the center of the head just above the eyes, ranging ...
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 Masai giraffe (Giraffa tippelskirchi [2]), also spelled Maasai giraffe, and sometimes called the Kilimanjaro giraffe, is a species or subspecies of giraffe. It is native to East Africa. The Masai giraffe can be found in central and southern Kenya and in Tanzania. It has distinctive jagged, irregular leaf-like blotches that extend from the ...
Giraffe necks do more than help them reach high leaves in trees. They can keep a lookout for predators, but there is another reason they may have such long necks. Some scientists think giraffes ...

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.
