繁殖 Reproduction 

這些動物的社會結構在不同物種之間存在很大差異.有些物種會建立永久性的社會群體,但很多其他物種則是多雄多雌的多配偶制,一隻雄性照顧著兩隻或更多的雌性.另一方面,也有一些單配偶制的物種,會建立暫時性的集體育幼地,供多個母親照顧後代;還有一些物種則以十隻或更多的群體生

The group's social structures differ greatly from one species to another. While some species create permanent social groups, many others are promiscuous and keep harems of two or more females under their care. On the other hand, there are monogamous species which establish transient colonial creches to tend to the offspring of several mothers; and others who live in groups of ten or more, occasionally even more. Each group consists of a single dominant male, several females, subordinate males, and juveniles.
