Podocnemis sextuberculata
Podocnemis sextuberculata 概述 六疣侧颈龟（Podocnemis sextuberculata）是南美洲亚马逊流域的中型淡水龟，背甲具六个疣突，IUCN列为濒危物种。
趣闻 由意大利动物学家Cornalia于1849年描述，种加词sextuberculata意为‘六个疣突’。当地俗称Iaçá、Pitiú等，幼体疣突显著，是重要食用龟类。
形态特征 最大背甲长雄性25.0 cm，雌性34.0 cm。背甲较平，幼体具六个明显结节状疣突，成年后可能变平。头大，吻突出，体色橄榄绿或褐色。
生态习性 栖息于亚马逊河流域的湖泊、河流和泛滥平原。植食性为主，亦取食少量动物性食物。繁殖期在洪水退后，雌龟于高河岸产卵。
主要威胁与保护 过度捕捞（肉和卵）、栖息地丧失（水坝、采矿、农业）及宠物贸易。保护措施包括CITES管制、IUCN评估及部分保护区管理。
自然分布与保护状态 分布于玻利维亚、巴西、哥伦比亚、秘鲁等国，可能包括厄瓜多尔。AOO约614,881 km²，EOO约2,874,370 km²。IUCN红色名录：濒危（EN A2ad+4cd），CITES附录II。
