Groups travel their territory by leaping from one tree trunk to another, and are led by a dominant breeding male and 2 breeding females. A group may travel up to 1.2 miles per day usually by leaping from tree to tree. Leaps reaching 13 feet without any loss of height have been recorded. Unlike all other small new world monkeys that have 32 teeth, the Goeldi’s monkeys have 36 teeth.
