Mountain Gorilla

The mountain gorilla (Gorilla Beringei Beringei) is a subpecies of the Eastern Gorilla dubbed as critically endangered by the IUCN Redlist.

Adult males are called silverbacks because a saddle of gray or silver-colored hair develops on their backs with age. 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 (350–500 lb). The tallest silverback recorded was a 1.94 m (6.4 ft) individual shot in Alimbongo, northern Kivu in May 1938 and the heaviest was a 1.83 m (6 ft) individual.

Reasons for its endangerment are poaching, habitat loss, and disease.
