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.
The term "horn" is also popularly applied to other hard and pointed features attached to the head of animals in various other families: Giraffidae: Giraffes have one or more pairs of bony bumps on their heads, called ossicones. These are covered with furred skin. Cervidae: Most deer have antlers, which are not
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.
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.
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.
Baby giraffes are pretty active almost from the moment they are born. Within an hour or so after being born, the baby (called a calf) is ready to take its first steps.
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.
