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.
It had been argued that the so-called ossicones known from fossils were actually horns, but later research showed that these structures are consistent with the ossicones of giraffes and okapi. [6] The following is a list of some ossicone-bearing genera: Giraffidae †Bramatherium (2 pairs) †Decennatherium (1 pair) Giraffa (giraffes; 1 pair)
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 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.
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
A group of giraffes is called a tower. While the females live together, males may live alone or in small bachelor groups. Real fights are rare among giraffes and they are typically over mating ...
All insects have antennae, however they may be greatly reduced in the larval forms. Amongst the non-insect classes of the Hexapoda, both Collembola and Diplura have antenna, but Protura do not. [9] Antennal fibrillae play an important role in Culex pipiens mating practices. The erection of these fibrillae is considered to be the first stage in ...
