[48]:71 They comprise 5254 per cent of the length of the giraffe's vertebral column, compared with the 2733 percent typical of similar large ungulates, including the giraffe's closest living relative, the okapi. [142] In 2019, giraffes were listed under Appendix II of the Convention on International Trade in Endangered Species (CITES), which means international trade including in parts/derivatives is regulated. Their food source is leaves, fruits, and flowers of woody plants, primarily acacia species, which they browse at heights most other herbivores cannot reach.

Males establish social hierarchies through "necking", combat bouts where the neck is used as a weapon. Home ranges are as small as 85 square km (33 square miles) in wetter areas but up to 1,500 square km (580 square miles) in dry regions. Such large surfaces cool a network of blood vessels that move blood throughout the body. [43], Reproduction in giraffes is broadly polygamous: a few older males mate with the fertile females. [117], The local, seasonal presence of large herds of migratory wildebeests and zebras reduces predation pressure on giraffe calves and increases their survival probability. "Correlates of home range sizes of giraffes, "How do giraffes locate one another? It is thought that this occurs due to certain antioxidant enzymes and their roles in the brain.

Quantitative macroscopic anatomy of the giraffe (Giraffa camelopardalis) digestive tract. Anatomia, histologia, embryologia 45.5 (2016): 338-349. [123]:49, Giraffes have a presence in modern Western culture. The camel and the giraffe are the only other animals that move in this way. Metabolic water is water created inside a living organism through its metabolism, by oxidizing energy-containing substances of food. Giraffes Have A Four-Chambered Stomach, Camels Three-Chambered One, 1. In the 13th century, East Africa supplied a trade in hides. [59] Along the neck is a mane made of short, erect hairs. Despite the difference, they have the same amount of neck bones. [48]:7879 The giraffe requires less food than many other herbivores because the foliage it eats has more concentrated nutrients and it has a more efficient digestive system. The rumen was the largest compartment followed by the abomasum, then the reticulum, and the omasum.

The giraffe's chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its spotted coat patterns. [22], A 2020 study showed that depending on the method chosen, different taxonomic hypotheses recognizing from two to six species can be considered for the genus Giraffa.

Despite David Mitchell's funny rant about the origin of the word camelopard, an archaic English word for giraffe, camelopard is not a product of a 17 th century predecessor of whoever invented the word "phablet". This advantage is real, as giraffes can and do feed up to 4.5m (15ft) high, while even quite large competitors, such as kudu, can feed up to only about 2m (6ft 7in) high. They are formed from ossified cartilage, covered in skin and fused to the skull at the parietal bones. [106] Calves first ruminate at four to six months and stop nursing at six to eight months. We are going to look at the camel, the giraffe, and the penguin to see the features of their bodies that help them live in their specific habitat. Giraffes sleep a lot less than camels, have a four-chambered stomach while camels have three-chambered one, and do not spit as camels do. [43] The coat pattern has been claimed to serve as camouflage in the light and shade patterns of savannah woodlands. Seems to serve a social purpose rather than primarily for scratching itches. Giraffes live in nonterritorial groups of up to 20. Because males have a stronger odour than females, it may also have a sexual function.

[48]:76 When the animal lowers its head, the blood rushes down fairly unopposed and a rete mirabile in the upper neck, with its large cross-sectional area, prevents excess blood flow to the brain. However, habitat type has an effect on foraging ecologies of both giraffe sexes, but habitat did not inuence camel foraging. [91] Masai giraffes in Tanzania sort themselves into different subpopulations of 6090 adult females with overlapping ranges, each of which differ in reproductive rates and calf mortality. they are all four legged, hoofed, mammals. [54], The fur may give the animal chemical defense, as its parasite repellents give it a characteristic scent.
