gorilla, an ape ape, any primate of the subfamily Hominoidea, with the possible exception of humans. The small apes, the gibbon and the siamang, and the orangutan , one of the great apes, are found in SE Asia.
..... Click the link for more information. , Gorilla gorilla, native to the lowland and mountain forests of western and central equatorial Africa. It is the largest of the apes, the males reaching a height of 5 to 6 ft (150–190 cm) with a 9-ft (144–cm) arm spread. Males weigh about 450 lb (200 kg) in the wild; in zoos they become obese and may reach 600 lb (270 kg) or more. The two species of gorilla are the western, comprising the western lowland (G. gorilla gorilla) and Cross River (G. gorilla diehli) gorillas, and the eastern, comprising the eastern lowland (G. beringei graueri) and mountain G. beringei beringei gorillas. The Cross River gorilla of the Nigeria-Cameroon border region and the mountain gorilla of Rwanda, Congo (Kinshasa), and Uganda each number in the hundreds and are closest to extinction. The western lowland gorilla is the most numerous, with some 100,000 individuals. Male gorillas have prominent sagittal crests and brow ridges and large canine teeth; these features are less developed in females. Females are smaller than males, weigh about half as much, and do not develop the gray hair on the back characteristic of the sexually mature male. Dominant older males, called silverbacks, usually lead stable harem societies of 2 to 30 females and juvenile males in a daily search for food. The animals normally walk on all fours, resting their upper body on their knuckles. They are vegetarians, living on a variety of vines, leaves, fruit, roots, and bark. Mountain gorillas eat wild celery, bamboo shoots, nettles, thistles, and sometimes certain soils or a rare form of fungus. Adolescents and small females may climb trees in search of food and to build arboreal nests for sleeping. Adults of both sexes build ground nests daily. Quiet and retiring in temperament when compared to the excitable chimpanzee chimpanzee, an ape , genus Pan, of the equatorial forests of central and W Africa. The common chimpanzee, Pan troglodytes, lives N of the Congo River. Full-grown animals of this species are up to 5 ft (1.

Gorillas normally rely on bluffs, roaring and beating their chests to frighten intruders. Their main enemies are human poachers; in the lowlands, leopards may sometimes eat the young. Females bear one infant about every four years; the child is carried in the mother's arms and then on her back. Females mature in 8 or 9 years, males in 11 or 12; gorillas may live more than 40 years. Gorillas are classified in the phylum Chordata Chordata (kôrdā`tə,–dä`–)

Largest of the great apes. A stocky, powerful forest dweller native to equatorial Africa, the gorilla (Gorilla gorilla) has black skin and hair, large nostrils, and prominent brow ridges. Adults have long, powerful arms; short, stocky legs; an extremely thick, strong chest; and a protruding abdomen. Adult males have a prominent crest on top of the skull and a “saddle” of gray or silver hairs on the lower part of the back. Males, about twice as heavy as females, may reach a height of about 5.5 ft (1.7 m) and a weight of 300–600 lbs (135–275 kg). Gorillas are mainly terrestrial, walking about on all four limbs. They live in stable family groups of six to 20 animals that are led by one or two silverbacked males. They eat leaves, stalks, and shoots. They are unaggressive and even shy unless provoked. They are calmer and more persistent than chimpanzees; though not as adaptable, gorillas are highly intelligent and capable of problem solving. The gorilla is hunted for its body parts and meat, and its habitat is disappearing. It is an endangered species throughout its range; the mountain subspecies is critically endangered.
