CITES: Appendix I

Population in Wild: No published estimates; threatened by habitat loss, hunting and trapping

Locomotion: Arboreal quadrupeds, primarily leaping

Activity Cycle: Cathemeral year-round; some seasonal variations in activity patterns

Social Groups: Live in multi-male, multi-female groups; no apparent dominance hierarchy

Diet: Diverse diet of over 120 plant species. Primarily consumes ripe fruit; also eats flowers and leaves. Occasionally eats invertebrates.

Predators: Fossa (Cryptoprocta ferox), diurnal raptors and humans

Reproduction & Development Species Highlights

Sexual Maturity: c. 3 years, in managed care

Gestation: c. 120-128 days, in managed care

Litter Size: 1-2; a single offspring is most common

Birth Weight: 60-90 g (2-3 oz)

Age at Weaning: Begins at 3-4 months, proceeds gradually

Typical Life Expectancy:
