📖 1. Overview
The Northern White-cheeked Crested Gibbon is an arboreal gibbon that rarely comes down from the canopy of subtropical forests, and males and females differ in coat color.
🦴 2. Anatomy & Morphology
It has no tail and exceptionally long forelimbs and hindlimbs. Infants are born cream-colored and turn black with white cheek patches at about two years old; adult males remain black with white cheeks, while females turn back to cream.
🔍 3. Ecology & Behavior
It feeds mainly on fruit pulp along with leaves, flowers, and insects, acting as a seed disperser. It swings through branches by brachiation and lives in family groups of a mated pair and their young, foraging throughout the day.
