金腹捲尾猴

金腹捲尾猴體長36-42釐米；尾長38-49釐米；重量1.4-4.8公斤。雄性略大。 金腹捲尾猴的胸部、腹部及上臂呈黃色至金色，但個別或性別之間存在着些微不同。面部呈淺褐色，冠呈深或淺褐色。金腹捲尾猴並沒有明顯的毛簇，大部份都是位於頭部背面，故較難見到。上面部有短毛，眼睛周園較深色。四肢及尾巴都較為深色。 以往相信它們是黑帽捲尾猴的亞種，但現已成為獨立的物種。 ^[1] 

金腹捲尾猴孕期大約180天，通常每胎產1仔。雌性4歲性成熟。 ^[1] 

以往金腹捲尾猴棲息在聖弗朗西斯科河東面及北面的地區，但由於人類的騷擾，它們現只分布在巴西巴伊亞東南部的大西洋沿岸熱帶雨林中。 ^[1] 

金腹捲尾猴分佈圖：

The golden-bellied capuchin (Sapajus xanthosternos), also known as the yellow-breasted or buffy-headed capuchin, is one of several species of New World monkeys.

Although there are differences between individuals as well as between the sexes and across age groups, C. xanthosternos is described as having a distinctive yellow to golden red chest, belly and upper arms. Its face is a light brown and its cap for which the capuchins were first named is a dark brown/black or light brown. Formerly thought to be a subspecies of tufted capuchin (C. apella), it was elevated to the status of species. ^[1]
