新浪环球地理讯 北京时间12月19日消息，近日，科学家发现了新的灵长类物种，
学名为Nycticebus kayan 的新种懒猴。懒猴体形小巧，夜间活动，主要生活在南亚和
东南亚。由于行动缓慢和夜行习性，科学界对它们知之甚少。
不过，科学家还是能够根据面部特征来区分不同的懒猴物种。研究团队仔细检查了
博物馆里的几个懒猴标本，与拍摄于婆罗洲的懒猴Nycticebus menagenis 图片进行对
比。脸部特征的差异显示，有三个懒猴亚种被错误地归为N. menagenis，其中两种之前
还被定为亚种N. kayan，而后者现在确定是全新的物种。
研究合著者，密苏里大学哥伦比亚分校的雷切尔·穆德斯(Rachel Munds)说，N.
kayan 的面部具有“非常独特、引人注目的眼纹，能延伸至脸颊，婆罗洲的其他物种都
没有这样的特征。”
与所有的懒猴一样，N. kayan的咬伤具有毒性，这是极少数哺乳动物才具有的能力
。为了获得毒液，懒猴会用手摩擦腋窝附近的腺体，之后将毒液涂在牙齿上。人或捕食
者若被懒猴咬伤，将导致致命的过敏性休克。
穆德斯说，懒猴可能会利用毒液进行捕猎，甚至是保护幼崽。有证据显示，懒猴母
亲在离开孩子去觅食之前，会将毒液涂到幼崽的身上，以此威慑潜在的捕食者。
然而，就算拥有致命的毒液，懒猴也无法阻挡非法宠物贸易带来的捕猎活动。巨大
的需求使得国际自然保护联盟将N. menagenis列为易危物种。穆德斯推测新种懒猴N.
kayan也将如此。穆德斯说，更多地了解婆罗洲的懒猴物种，将有助于自然保护者更好
地拯救这些“迷人的小生灵。”(任天) |

Although their bite can be toxic, slow lorises are rather timid and easy to
capture from the wild. As I wrote earlier this year, slow lorises are
available in Indonesian markets for as little as $20, where they are stuffed
into tiny cages after sellers rip out their front teeth and venomous elbow
patches with pliers, nail clippers or wire cutters. Many of the animals die
shortly after being sold, as the removal of their teeth can hamper their
ability to eat and owners try to play with them during the day, disturbing
their normal sleep patterns. |
