Wildlife in Serengeti-Park
Geoffroy’s Tufted-ear Marmoset | Callithrix geoffroyi
Geoffroy’s tufted-ear marmoset or white-fronted marmoset live in the eastern coastal forests of Brazil and belong to the marmoset family. These little tree dwellers weigh only about 200-350 grams with a head-hull length of 20 inches and a 30-inch tail. The diet of these diurnal animals consists mainly of tree juices, as well as fruits and insects.
White-fronted marmosets live in families of eight to ten animals in five-hectare territories. Although there are several adult females in a group, only the dominant females reproduce with one male. The ovulation of the other females is suppressed by the release of fragrances (hormones) of the dominant female. After a gestation period of about 150 days, twins are usually born, and all group members participate in their rearing and grooming.
