Giraffes have become popular attractions in modern zoos, though keeping them is difficult as they prefer large areas and need to eat large amounts of browse. Captive giraffes in North America and Europe appear to have a higher mortality rate than in the wild, the most common causes being poor husbandry, nutrition, and management.
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).
South America also once had a great diversity of ungulates of native origin, but these dwindled after the interchange with North America, and disappeared entirely following the arrival of humans. Sequencing of collagen from fossils of one recently extinct species each of notoungulates and litopterns has indicated that these orders comprise a ...
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]
Northern giraffes live in savannahs, shrublands, and woodlands. After numerous local extinctions, Northern giraffes are the least numerous giraffe species, and the most endangered. In East Africa, they are mostly found in Kenya and southwestern Ethiopia, and rarely in northeastern Democratic Republic of the Congo and South Sudan.
The South African giraffe is found in northern South Africa, southern Botswana, southern Zimbabwe, and south-western Mozambique. [6] After local extinctions in various places, South African giraffes have been reintroduced in many parts of Southern Africa, including in Eswatini. They are common in both in and outside of protected areas. [1]
Giraffes are peaceful animals and rarely harm humans. They are not aggressive by nature, and like the giraffe in this video, they main defense mechanism is using their strong legs to kick.
Metatherians spread westward into modern North America (still attached to Eurasia) and then to South America, which was connected to North America until around 65 mya. Marsupials reached Australia via Antarctica about 50 mya, shortly after Australia had split off suggesting a single dispersion event of just one species. [ 159 ]
