Giraffes have a characteristic coat pattern of brown patches in a lighter background. [24], Fully grown giraffes stand 4.3–5.7 m (14.1–18.7 ft) tall, with males taller than females. Intermittent short "deep sleep" phases while lying are characterised by the giraffe bending its neck backwards and resting its head on the hip or thigh, a position believed to indicate paradoxical sleep. [42] Being vascularized, the ossicones may have a role in thermoregulation,[53] and are also used in combat between males. Dali considered the giraffe to be a symbol of masculinity, and a flaming giraffe was meant to be a "masculine cosmic apocalyptic monster". [50]:27, The front and back legs of a giraffe are about the same length. They swing their necks towards each other and the one which remains standing is the winner and wins mating rights for that area. With each step, the animal swings its head. Lake Eyasi, NW [1] [126] As of 2010[update], there were more than 1,600 in captivity at Species360-registered zoos. [1] In 1999, it was estimated that over 140,000 giraffes existed in the wild,[31] but estimations as of 2016 indicate that there are approximately 97,500 members of Giraffa in the wild, down from 155,000 in 1985. [136], Giraffes were probably common targets for hunters throughout Africa. It is traditionally considered to be one species, Giraffa camelopardalis, with nine subspecies. [133] Translocations are sometimes used to augment or re-establish diminished or extirpated populations, but these activities are risky and difficult to undertake using the best practices of extensive pre- and post-translocation studies and ensuring a viable founding population. [10] During this time, tropical plants disappeared and were replaced by arid C4 plants, and a dry savannah emerged across eastern and northern Africa and western India. Camelopardalis antiquorum. However, for the first 1–3 weeks, it spends most of its time hiding;[95] its coat pattern providing camouflage. [10] They also feed on shrubs, grass and fruit.
