The African buffalo or Cape buffalo (''Syncerus caffer''), is a large African bovine. It is not closely related to the slightly larger wild Asian water buffalo, and its ancestry remains unclear. ''Syncerus caffer caffer'', the Cape buffalo, is the typical subspecies, and the largest one, found in South and East Africa. ''S. c. nanus'' (forest buffalo) is the smallest subspecies, common in forest areas of Central and West Africa while ''S. c. brachyceros'' is in West Africa and ''S. c. aequinoctialis'' is in the savannas of Central Africa. The adult buffalo's horns are its characteristic feature; they have fused bases, forming a continuous bone shield referred to as a "boss". It is widely regarded as a very dangerous animal, as it gores and kills over 200 people every year. The African buffalo is not an ancestor of domestic cattle, and is only distantly related to other larger bovines. Owing to its unpredictable nature, which makes it highly dangerous to humans, the African buffalo has never been domesticated unlike its Asian counterpart, the water buffalo. Other than humans, African Cape buffaloes have few predators aside from lions and are capable of defending themselves. Being a member of the "big five" game family, the Cape buffalo is a sought-after trophy in hunting. ==Description== The African buffalo is a very robust species. Its shoulder height can range from and its head-and-body length can range from . Compared with other large bovids, it has a long but stocky body (the body length can exceed the wild water buffalo, which is heavier and taller) and short but thickset legs, resulting in a relatively short standing height. The tail can range from long. Savannah-type buffaloes weigh , with males normally larger than females, reaching the upper weight range.〔Raphael, Marcel (2006) (African Buffalo ).〕 In comparison, forest-type buffaloes, at , are only half that size.〔Boitani, Luigi, ''Simon & Schuster's Guide to Mammals''. Simon & Schuster/Touchstone Books (1984), ISBN 978-0-671-42805-1〕 Its head is carried low; its top is located below the backline. The front hooves of the buffalo are wider than the rear, which is associated with the need to support the weight of the front part of the body, which is heavier and more powerful than the back. Savannah-type buffaloes have black or dark brown coats with age. Old bulls have whitish circles around their eyes. Females tend to have more-reddish coats. Forest-type buffaloes are reddish brown in colour with horns that curve back and slightly up. Calves of both types have red coats. A characteristic feature of the horns of adult male African buffalo is fusion of their bases, forming a continuous bone shield referred to as a "boss". From the base, the horns diverge downwards, then smoothly curve upwards and outwards. In large bulls, the distance between the ends of the horns can reach upwards of one metre. The horns form fully when the animal reaches the age of five or six years. In cows, the horns are, on average, 10–20% smaller, and the boss is less prominent. Forest buffalo horns are smaller than those of the savannah buffalo, usually measuring less than , and are almost never fused. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「African buffalo」の詳細全文を読む スポンサード リンク
