Most gorillas inhabit lowland tropical rainforests and montane rainforests between 1500 - 3500 m (4900 - 11,500 ft). Different populations have exhibited preferences for forest margins, secondary forest, swamp forests, bamboo forests, riverside forests and primary forest.

Adult females are often half the size of a silverback, averaging about 140 cm (4 ft 7 in) tall and 100 kg (220 lb).

However, obese gorillas in captivity have reached a weight of 270 kg (600 lb).Gorillas have a facial structure which is described as mandibular prognathism, that is, their mandible protrudes farther out than the maxilla. Eastern gorillas are darker colored than Western gorillas, with Mountain gorilla being the darkest of all. Mountain gorillas also have the thickest hair. The Western lowland gorilla can be brown or grayish with a reddish forehead. In addition, gorillas that live in lowland forests are more slender and agile than the more bulky Mountain gorilla. Almost all gorillas share the same blood type B and, like humans, have individual finger prints. The gorilla is primarily terrestrial but is fully capable of climbing. Some have been observed feeding in trees at heights of 40 m (130 ft), and even a large male, weighing at least 200 kg (440 lb), frequently climbed to 20 m (65 ft). Contrary to general opinion, the gorilla is not afraid of water. Recent studies of the western lowland gorilla have shown that it is quite happy to wade around in swamp forests in search of edible aquatic plants. Gorillas are
