Gemina lived an almost-normal life for a zoo giraffe, [2] except that she had to be fed separately; her keepers noted that her tongue was shorter than those of the other giraffes, and she did not have peripheral vision to the same extent that normal giraffes do.
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.
A Snellen chart is an eye chart that can be used to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Herman Snellen who developed the chart in 1862 as a measurement tool for the acuity formula developed by his professor Franciscus Cornelius Donders .
Giraffes, just like humans, have seven cervical vertebrae. Unlike humans, giraffe cervical vertebrae are attached to each other with ball and socket joints, making them able to bend their necks in ...
Giraffes have one of the shortest sleep durations among all land mammals, and according to Wildlife FAQ, "On average, adult giraffes sleep for about 30 minutes a night, and their sleep cycles are ...
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]
Giraffes can be pregnant for 15 months — almost twice the length of human. But that allows giraffe newborns to be born in the "superman" position; front legs and head first, followed by the rest ...
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.
