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.
South African giraffes usually live in savannahs and woodlands where food plants are available. Giraffes are herbivorous. They feed on leaves, flowers, fruits and shoots of woody plants such as Acacia. South African giraffes live in a fission–fusion society system based on factors such as sex, age, season, and kinship.

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 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).
The “plain brown” giraffe was seen on a game reserve in southwestern Africa, a wildlife organization said.
Southern giraffes have rounded or blotched spots, some with star-like extensions on a light tan background, running down to the hooves. They range from South Africa, Angola, Namibia, Botswana, Zambia, Zimbabwe, Mozambique. Their approximate population is composed of 44,500 to 50,000 individuals. [5]
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 ...
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.
