Western Lowland Gorilla: Gorilla Gorilla Gorilla
Distribution and Habitat
Lowland gorillas may be found in the area of the Congo River basin in west-central Africa.
These gorillas can be found in lowland rainforests.
Gorillas are the largest members of the primate family. Height ranges from four to six feet and weight ranges from 150-450 pounds. A gorilla’s arm span can reach lengths of nine feet and is greater than their standing height. Males tend to be larger and heavier than the females. Like other apes, they have no tails. Their hair is coarse and black, sometimes brown closer to the head. A saddle of gray hair develops across the lower back of mature males, hence the name silverback. Mature males also possess a pad of skin and connective tissue on their crowns which gives their head a conical shape.
Gorillas communicate with posture, facial expressions and vocalizations. The chest-beating display of males is a ritualized sequence of nine discreet acts culminating in chest-beating with cupped hands. Its function is most likely intimidation not a threat.
Gorillas are the rarest of man-like apes.
