The Javan surili (''Presbytis comata'') is an endangered species of Old World monkey endemic to the western half of Java, Indonesia, a biodiversity hotspot. Other common names by which it is known by include gray, grizzled or Sunda Island surili; grizzled or stripe-crested langur; Javan grizzled langur; grizzled, Java or Javan leaf monkey; langur gris.〔(【引用サイトリンク】 Grizzled Leaf Monkey )〕 There are two subspecies of the Javan surili: * ''Presbytis comata comata'' - Occurs in western Java * ''Presbytis comata fredericae'' - Occurs in central Java This colobine species has a sacculated stomach to assist the breakdown in the cellulose from the leaves it feeds on. It has a small, slender face and tail, and large round stomachs. Its coloring ranges from dark gray to white. Leaf monkeys tend to be active during the day, spending up to 5 hours grooming themselves. == Distribution == The Javan surili is found in the western half of Java, Indonesia. It ranges as far east as Mt. Lawu on the border with East Java.〔 According to a recent study, this species is mostly confined to Sundaland due to changes in the geography, sea level and vegetation that occurred during the Pleistocene era, and partly due to the type of vegetation and soil there today. The Javan surili lives in primary and secondary lowland rainforests, with an altitudnal range of 2500 meters.〔(【引用サイトリンク】 Grizzled Leaf Monkey (''Presbytis comata'') )〕 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「Javan surili」の詳細全文を読む スポンサード リンク
