GORILLAS, CLOSEST RELATIVES OF HUMANS

Gorillas are the closest relatives of humans. Gorillas are different from monkeys for a variety of reasons:
They are larger, walk up right for a larger period of time, dont have tails and have much larger, more developed brains.

There are four subspecies of gorillas:
The eastern low land gorilla
The mountain gorilla
The western low land gorilla
And the cross river gorilla

Gorilla have arms longer than than their legs and tend to walk on all their four limbs at certain times- a movement called "knuckle walking."
Adult males are known as SLIVER-BACK due to the distinctive silver coloured hair on their backs.

DIET
Gorillas are-herbivores and eat leaves,shoots,roots,vines and fruits.

BEHAVIOUR
Gorillas are ground dwelling and live in groups of 6-12 with the oldest and largest sliver-back  leading a family of females, their young and younger males called BLACK-BACKS.
The sliver-back makes the decision on when his groups wakes up, eats, moves  and rest for the night. because it his duty to protect his family all the time.
The sliver-back tends to be the most aggressive. In such situations, he beats his chest and charge at the perceive of threat.
