Reproduction:   Gestation lasts 139-180 days and normally results in one offspring. However, twins have been known to occur in captivity. The young are weaned at an average of 65 days. Young are cared exclusively for by the mother for the first 2 weeks at which time much of the care of the infant is handed over to the father.

General Information:   Discovered by E.A. Goeldi in 1904, the diurnal Goeldi’s monkeys can be found in groups ranging from 5-8 individuals. 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.


Predators:  Poachers, raptors, jaguars, and ocelots.

Conservation Status:  Listed as Vulnerable under the IUCN Red List and CITES appendix l due to its specialized habitat requirements, deforestation, and hunting.
