Gorilla Appearance
Gorillas are the biggest primates. They can become very heavy, and are very strong. A male gorilla can weigh up to 225 kilograms and stand 1.8 meters in height. Gorillas are peaceful animals that live in family groups called troops. They have a broad chest, wide shoulders, short legs, and long, powerful, strong arms. They have black skin and fur. Because of that older males are called 'silverbacks'.
