Second, a system of multiple matings by both females and males or multi-females are usually the largest of primate societies. Some groups can reach 300 individuals in these cases. Third, polygynous groups contain one adult male and several adult females and off-spring and are moderate in size. Gorilla troops fit this profile. Keep in mind that polygynous groups such as this, also called harems, maximize reproduction by keeping a pool of receptive females available.
All primates are social animals.
They interact on a regular basis with each other. Most tend to move, feed, and sleep in groups. The composition of these groups differs from species to species. The simplest social group found among primates is the noyau. It is commonly found among noctural primates and is based on an individual female and her offspring.
