Saguinus imperator

Emperor Tamarin (scientific name: Saguinus imperator) is also known as Emperor Tamarin in English. It has two subspecies.

The emperor tamarin has sharp vision, but poor hearing and smell. It lives in the upper canopy of the rainforest almost all its life and rarely moves on the ground, because food can provide it with enough water without having to look for water sources. It lives in clusters, with about 3-15 in each group, and up to 40. It is active during the day and sleeps in tree holes at night. The oldest female leads several males, who help each other. Emperor Tamarins often stay with other marmosets (such as saddleback tamarins). They can make different sounds to identify intruders.

Emperor Tamarins can mate and reproduce all year round. The marriage is polygamous, polyandrous and monogamous. All males in the family, whether they are fathers or not, will help give birth, care for and support the baby monkeys, and bring the baby monkeys to the mother monkeys for feeding. The young monkeys are weaned after about 3 months and reach sexual maturity at the end of the second year. The gestation period of the female is about 140-145 days, with 1-3 cubs per litter, but usually 2. Newborn marmosets will climb onto their parents' backs to follow their parents' activities and forage for food. They can move freely at 6-7 weeks old, are weaned after 2-3 months, reach sexual maturity at 16-20 months old, and live 17-20 years.
