Males typically have thicker ossicones that become bald on top due to frequent necking. [4] 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 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 Giraffes, Northern giraffes can be differentiated by the shape and size of the two distinctive horn-like protuberances known as ossicones on their foreheads; they are longer and larger than those of southern giraffes. Bull Northern giraffes have a third cylindrical ossicone in the center of the head just above ...
The third ossicone can often be seen in the center of the giraffe's forehead, and the other two are behind each ear. Regarding the hybridization and habitat of the species: Rothschild’s giraffes have different genetic markers that other species usually do not, which keeps their populations safe from extinction and hybridization overlap.
Rather than taking advantage of this, the opposing giraffe lines up head-to-toe, or head-to-head with the other giraffe. Each giraffe gets to fight from their preferred side.

The U.S. Fish and Wildlife Service has proposed new protections for giraffes, saying their populations are threatened by poaching, habitat loss and climate change. Giraffes need endangered species ...
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).
