Adult males are called silverbacks. When they reach sexual maturity, a saddle of gray or silver-colored hair develops on their backs. The hair on their backs is shorter than on most other body parts, and their arm hair is especially long. Upright, males reach 1.5–1.8 m (5–6 ft) in height, with an arm span of 2.25 m (7 ft 6 in) and weigh 204–227 kg (450–500 lb).
