I am Aswini.I am going to tell about Gorilla.
The gorilla, the largest of the primates, is a ground-dwelling herbivore that inhabits the forests of central Africa. There are two species of gorilla, both in the genus Gorilla; each species has two subspecies.
Gorillas move about by knuckle-walking. Males range in height from 1.65 m to 1.75 m, and in weight from 140 kg to 165 kg. Females are about half the weight of males. Lifespan is between 30–50 years.
A silverback is an adult male gorilla, typically more than 12 years of age and named for the distinctive patch of silver hair on his back A silverback gorilla has large canines that come with maturity. Blackbacks are sexually immature males of up to 11 years of age. Silverbacks are the strong, dominant troop leaders. Each typically leads a troop of 5 to 30 gorillas and is the center of the troop's attention, making all the decisions, mediating conflicts, determining the movements of the group, leading the others to feeding sites and taking responsibility for the safety and well-being of the troop. Males will slowly begin to leave their original troop when they are about 11 years old, travelling alone or with a group of other males for 2–5 years before being able to attract females to form a new group and start breeding. While infant gorillas normally stay with their mother for 3–4 years, silverbacks will care for weaned young orphans.
