The Gorillas, scientifically known as Gorilla gorilla, are one of the four species of great apes that are the closest living relatives of humans. The other three are chimpanzees, bonobos and orangutans. They belong to the family Hominidae and have closely linked by DNA. They are large quite apes that live in Africa. There are four subspecies of gorillas viz. the eastern lowland or Grauer’s gorilla (Gorilla beringei graueri); the mountain gorilla (Gorilla beringei beringei); the western lowland gorilla (Gorilla gorilla gorilla); and the Cross River gorilla (Gorilla gorilla diehl).
Gorillas, like other great apes, have arms that are longer than their legs. So they follow knuckle-walking, although sometimes they are seen to walk bipedally for short distances. The height of adult males range fromn 1.65–1.75 metres (5 ft 5 in–5 ft 9 in). The weight varies from 150–200 kg (310–440 lb). As a common situation in animals, females are smaller and often half the size of male. Their height measures about 1.4 metres (4 ft 7 in) and weight 100 kg (220 lb). Obese gorillas in captivity have reached a weight of 270 kg (600 lb). Gorillas have a typical facial structure, which is described as mandibular prognathism. These species rarely drink water because they eat succulent vegetation that is comprised of almost half water.
Although gorillas are frequently portrayed as aggressive, dangerous killers, they are shy, peaceful vegetarians (expect some, which have seen to feed on ants and insects). They live in troops, which is led by silverback (an adult male). Because of massive loss of habitat, these majestic primates are in great danger of going extinct. Although several steps have been taken by many nations, the Gorilla Agreement is the first legally binding instrument exclusively targeting Gorilla conservation and came into effect on 1 June 2008.
