Capuchin monkey
Capuchins live in groups of 10 to 40 members. These groups consist of related females and their offspring, as well as several males. Usually groups are dominated by a single male.  The Capuchins in a group will groom each other and vocalize to communicate.  The Capuchin group will be protective of its territory, marking a central area of their territory with urine and defending it against intruders.
