上海动物园又添新成员 萌猴杰氏狨首次展出

原标题:上海动物园又添新成员 萌猴杰氏狨首次展出

暑期里上海动物园里新来了一群萌宝,它们是原产于巴西的杰氏狨。

杰氏狨Callithrix geoffroyi 得名于它们面部一圈厚厚的白毛,因此也称为白面狨,它们还有着胖乎乎的身体和长长的尾巴。

白面狨生性机警,连饲养员进去喂食的时候,它们也会小心翼翼地躲起来,在角落里警惕地张望。不过,大多数时候,它们还是很活泼的,喜欢在树枝之间跳来跳去。

动物园给它们提供了丰富的食物,有香蕉、苹果,黄瓜、胡萝卜、芹菜、馒头、鸡蛋、面包虫等。饲养员一般会在上午10点一刻,下午3点一刻左右喂食。展区内还铺设了树皮,种植了绿化,安装了空调,生活环境非常舒适。

一个杰氏狨群中通常会生活着多只雌性和雄性,但只有其中一只雌性占主导地位。到了繁殖季节,只有这只地位最高的雌性能参与繁殖,而其他雌性的繁殖则会受到抑制,避免发情和交配。

这种情况在灵长类中相当少见,有观点认为,这与狨猴多产双胞胎有关,因为要同时养育两个孩子,对狨猴母亲来说并不容易,因此雄性个体也会参与哺育后代,而增加了后代的存活率。
