silvery gibbon

The "silvery gibbon" is another name for the "silver gibbon," an ashy-gray primate found in Java and Borneo. Gibbons, belonging to the family Hylobatidae, are small apes native to the tropical forests of Southeast Asia. They are known for their long arms, used for brachiation (swinging from branches), and their loud, musical calls.12

Gibbons are arboreal, meaning they live in trees, and move with great agility. They typically live in small, monogamous groups and defend their territories. Their diet consists mainly of fruit, supplemented with leaves, insects, and bird eggs. Gibbons are considered among the most endangered primates due to habitat destruction and hunting.2
