Tamarins Marmosets and Goeldi's Monkey: Callitrichidae

Callitrichids And People

Marmosets and tamarins are sold as pets. These animals are commonly used in medical research, especially in the United States.


In tamarin and marmoset groups, just one female gives birth, producing twins each time. At birth, the twins weigh as much as 25 percent of the mother's weight. Juvenile siblings and other adults help take care of the infants, sharing food after the infants are weaned from milk and guarding them against predators. Family members take turns carrying the twins, especially since there are no places to set the babies down in tree tops.
