大鼻猴濒危级别比大熊猫还高

2017-09-15 09:51:48   中国青年网

大鼻猴又称长鼻猴,是东南亚加里曼丹岛的特有动物,是目前唯一发现的不属于反刍亚目却能够反刍的物种。其中雄性猴子随着年龄的增长鼻子会越来越大,最后形成像茄子一样的红色大鼻子,而雌性的鼻子却比较正常。大鼻猴栖息于当地的红树林、沼泽及河畔的森林。因为当地森林被大批采伐利用,已经严重毁坏了所剩不多的大鼻猴栖息地。有数据显示,大鼻猴目前全球仅剩1000余只,列入《世界自然保护联盟》(IUCN)2000年濒危物种红色名录濒危级别,比中国国宝大熊猫的易危级别还要高。

大鼻猴是群居性动物,一般以10~20只个体为一个家族。雄性大鼻猴比雌性大鼻猴体型大很多。又因为雄性的生殖器一天里有超过三分之二的时间都处在坚挺的状态,所以大鼻猴又有“金枪不倒”的外号。

大鼻猴最主要的食物是树叶,它们有一个巨大的胃专门用于消化树叶。值得一提的是,大鼻猴的胃对糖分很敏感,所以不能吃太甜的东西。由于树叶含有很多的纤维素,所以大鼻猴一天里有三分之二的时间都在打盹睡觉,让胃肠道充分地消化树叶,这点跟澳洲国宝考拉有点相似。
