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 video above shows the fascinating way male giraffes fight. Known as “necking” the giraffes use their long and powerful necks to attack, delivering hard blows with each hit.
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.
At several zoos, Masai giraffe cows have become pregnant and successfully given birth. [20] Masai giraffes can suffer from giraffe skin disease, which is a disorder of unknown etiology that causes lesion on the forelimbs. This disorder is being further investigated to better understand mortality in this species. [21]
The zoo shared the video on Wednesday, May 29th. It shows two male giraffes in their enclosure. One of them is sticking his neck through the bars to get to some tall grass on the other side.

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 ...
Giraffes sleep so little for two main reasons: to protect themselves (and their babies) from predators and because they're constantly on the move for food. As Fitz mentioned in the video they eat ...
