Second, Morphological Characteristics

Black-crowned Macaque is a medium to large monkey, with a male body length of 48-60 cm and a weight of 5.9 -10.4 kg, female body length 44-55 cm, weight 3.6-5.5 kg.

The black-crowned macaque has a stocky underbody, a short tail, short, bushy and rather silky hair, all black in color, long cheeks, brown eyes, and a high, ridge-like nose. The rump has a distinct distinctive pink color, the males are small and heart-shaped, and the females are larger and darker and round.

III. Living habits

The food of black-crowned macaques includes fruits, plant leaves, insects, mice, crabs and lizards. Sometimes food is not eaten immediately and is stored in the cheek pouch for a period of time.

Black-crowned macaques are active during the day and rest at night, and the dominant male in the group is responsible for guarding and preventing serious fights. Group members groom each other and purr to indicate a friendly relationship.

The distribution range of black-crowned macaques is very limited, and the number of black-crowned macaques has decreased by 80% compared with before. The main threats are habitat destruction and rampant hunting. Currently critically endangered on the Red List of Threatened Species, the 8,800-hectare Tangkoko Nature Reserve has established the Sulawesi Black-crowned Monkey Nature Reserve to prevent poaching and burning of trees and preserve the future of the habitat.
