Gorillas, the largest of the living primates, are ground-dwelling omnivores that inhabit the forests of Africa. Gorillas are divided into two species and (still under debate as of 2007) either four or five subspecies. Its DNA is 97% - 98% identical to that of a human, and are the next closest living relatives to humans after the two chimpanzee species.

Name :
The American physician and missionary Thomas Staughton Savage first described the Western Gorilla (he called it Troglodytes gorilla) in 1847 from specimens obtained in Liberia. The name was derived from the Greek word Gorillai (a "tribe of hairy women") described by Hanno the Navigator, a Carthaginian navigator and possible visitor (circa 480 BC) to the area that later became Sierra Leone.

Physical characteristics :
Gorillas move around by knuckle-walking. Adult males range in height from 165-175 cm (5 ft 5 in 5 ft 9 in), and in weight from 140-200 kg (310-440 lb). Adult females are often half the size of a silverback, averaging about 140 cm (4 ft 7 in) tall and 100 kg (220 lb). Occasionally, a silverback of over 183 cm (6 ft) and 225 kg (500 lb) has been recorded in the wild. 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.

Gestation is 8 months. There are typically 3 to 4 years between births. Infants stay with their mothers for 3-4 years. Females mature at 10-12 years (earlier in captivity); males at 11-13 years. Lifespan is between 30-50 years. The Philadelphia Zoo's Massa set the longevity record of 54 years at the time of his death.

Gorillas are omnivores, eating fruits, leaves, shoots, and sometimes insects which make up only 1-2% of their diet.

Almost all gorillas share the same blood type (B) and, like humans, have individual finger prints.
