The proboscis monkey (''Nasalis larvatus'') or long-nosed monkey, known as the ''bekantan'' in Indonesia, is a reddish-brown arboreal Old World monkey that is endemic to the southeast Asian island of Borneo. This species co-exists with the Bornean orangutan. It belongs in the monotypic genus ''Nasalis'', although the pig-tailed langur has traditionally also been included in this genus. The monkey also goes by the Indonesian name ''monyet belanda'' ("Dutch monkey"), or even ''orang belanda'' ("Dutchman"), as Indonesians remarked that the Dutch colonisers often had similarly large bellies and noses. This species of monkey is easily identifiable because of its unusually large nose. ==Taxonomy== Proboscis monkeys belong to the Colobinae subfamily of the Old World monkeys. The two subspecies are:〔 *''N. l. larvatus'' (Wurmb, 1787), which occupies the whole range of the species *''N. l. orientalis'' (Chasen, 1940), restricted to north-east Kalimantan However, the difference between the subspecies is small, and not all authorities recognise ''N. l. orientalis''.〔 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「proboscis monkey」の詳細全文を読む スポンサード リンク
