Like all gorillas, they live in small groups (or bands) of 6-7 individuals, including one silverback (adult male), a few females, and their young.

Anatomy: Gorillas have very long arms (the arms are longer than the legs), and a short, bulky body with a wide chest. They are covered with long, silky, black hair on most of their body (except their fingers, palms, face, armpits, and bottoms of the feet). Gorillas have a very large head with a bulging forehead, a crest on top (larger on males), tiny ears, and small, dark-brown eyes. They walk using their front knuckles and their feet. Gorillas range from 4.6-5.6 ft (1.4-1.7 m) tall. Males are much bigger than females.

Diet: Gorillas are mostly herbivores, eating mostly leaves and plant stems. Occasionally, gorillas eat termites and ants. An average adult male eats about 50 pounds of food a day. They rarely drink water.
