The Biggest Animals Kingdom | Giraffe | Giraffe has its first origin of the name known in the Arabic words Zarafa (زرافہ), probably some African languages. species name is the Latin word for giraffe. Giraffe is one of only two survivors of the family Giraffidae, the other the okapi. Other climate change caused the extinction of giraffes in Asia, while Africa has survived and is emitted in a number of new species. G. Giraffe appeared about 1 million years in East Africa during the Pleistocene. Some biologists believe that modern giraffes to G. find jumae G. gracilis is more likely candidate. Giraffe is one of the many species originally described by Linnaeus in 1758. He gave the name of the binomial Cervus Giraffe. Morten Thrane Brünnich classified in the genus Giraffa 1772. In the early 19th century, Jean-Baptiste Lamarck believed that the long neck of the giraffe was "acquired characteristic", developed by generations of ancestors as a giraffe trying to get to the leaves of tall trees. This theory was rejected in the end, and now scientists believe that the giraffe's neck appeared to Darwinian natural selection as the ancestors of giraffes with long necks and had a competitive advantage allowing them to better reproduce and pass their genes.

A fully grown giraffe is 5-6 meters (16-20 feet) in height, with men higher than women, the average weight is 1,600 kg (3,500 pounds) for adult males and 830 kg (1,800 pounds) for adult women. Despite its long neck and legs, the giraffe's body is relatively short. Located on both sides of the head, a big giraffe, rolling his eyes to teach him a panoramic view from a great height. Giraffes see in color, and their hearing and smell are also sharp. Prehensile tongue giraffe is about 50 cm (20 inches). The upper lip is a giraffe, a tenacious and is useful when searching for food. Each person has a unique giraffe fur. Leather Giraffe mostly gray. Along the animal's neck is a mane of short erect hairs. Giraffes usually inhabit savannas, grasslands and woodlands. Angolan Giraffe can be found in the desert environment. Giraffes browse on the twigs of trees, preferring trees of genera Acacia, Commiphora and Terminalia, which are an important source of calcium and protein to sustain growth rates of the giraffe. 

The giraffe eats about 34 kilograms (75 pounds) of leaves daily.When said that giraffes can chew the bark of twigs. Although grazing animals, the giraffe is known to visit the carcass and lick the dry bones of the meat. During the rainy season, food is abundant and giraffes are more common, while during the dry season, they gather around the evergreen trees and shrubs remain. In ruminant animals, giraffes chew food and then swallow for processing and then passes the half-digested much neck and back gum in his mouth to chew again. The giraffe requires less food than many other herbivores, because they eat the leaves of a higher concentration of nutrients and has a digestive system more efficient animal faeces in the form of small granules. It is common for a giraffe in the saliva during feeding. Giraffes are likely to have common goals for hunters from all over Africa. Tail hair flyswatters, bracelets, necklaces and wire. Smoke from the burning giraffe skin was used in the Buganda traditional healers for the treatment of bleeding from the nose. Habitat destruction affected the giraffe, too: in the Sahel, the need for firewood and grazing land for cattle room led to deforestation. 

In 1997, Jonathan Kingdon has suggested that the Nubian giraffe was the most endangered of all the giraffes in 2010, he can count at least 250, but this estimate is uncertain. Private game reserves have helped to save the population of giraffes in South Africa. Giraffe Manor in Nairobi, a popular hotel, which also serves as a sanctuary for Rothschild giraffes. The giraffe is a protected species in most of its range.
