The Cercopithecinae are a subfamily of the Old World monkeys, which comprises roughly 71 species, including the baboons, the macaques and the vervet monkeys. Most cercopithecine monkeys are limited to sub-Saharan Africa, although the macaques range from the far eastern parts of Asia through northern Africa, as well as on Gibraltar. == Characteristics == The various species are adapted to the different terrains they inhabit. Arboreal species are slim, delicate and have a long tail, while terrestrial species are stockier and their tail can be small or completely nonexistent. All species have well-developed thumbs. Some species have ischial callosities, which can change their colour during mating period. These monkeys are diurnal and live together in social groups. They live in all types of terrain and climate, from cool mountains to rain forests, savannah, bald rocky areas or even snowy mountains, such as the Japanese macaque. Most species are omnivorous, with diets ranging from fruits, leaves, seeds, buds, and mushrooms to insects and spiders to smaller vertebrates. All species possess cheek pouches in which they can store food. Gestation lasts approximately six to seven months. Young are weaned after three to 12 months and are fully mature within three to five years. The life expectancy of some species can be as long as 50 years. 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「Cercopithecinae」の詳細全文を読む スポンサード リンク
