Tamarins are very sensitive to any change in their environment, so any disturbance by humans in the rain forests may cause irreparable damage to their lives. The tamarin marks its group’s territory by scent. When two groups conflict over territory, the individuals expose their backsides and reproductive organs in order to scare the others and protect the territory. Interestingly, the tamarin has a specific call for each type of food it finds. The male cotton-top tamarin carries most of the responsibility for caring for the offspring and carries them from place to place on its back. The mother carries the offspring only for feeding.
