Facts On Gorillas

CdyDZFZWEAA-ZfoAbout five million years ago, the African apes like the gorillas, bonobos and chimpanzees diverged from a common ancestor, and they all belong to family Hominidae. They walk on all fours, which is called quadrupedalism. They carry their head and torso’s weight with the help of their knuckles. There are two species of gorilla. They are the Western gorilla and Eastern gorilla. Western has two subspecies called Western Lowland and Crosses River Gorilla whereas the Eastern gorilla has the subspecies of eastern lowland and the mountain gorilla.

It has been proved that gorillas portray individual personalities. They are also found to be capable of expressing emotions like grief. The gorillas live in sociable groups which are often led by male gorilla called silver back. This name is because the male is old and has silver hairs on its back. The group has females and infants. When other male gorillas grow up, they move away from their group to form a new group or join other groups. Different groups are found to live and co-exist in the same area peacefully.

Social bonds are reinforced by a group by social grooming. They groom each other by combing them using their teeth and fingers. They are mostly herbivores, and their diets comprise mainly of leaves, stems, fruits, shoots and sometimes include caterpillars, snails, grubs, ants, and termites.

The females start reproducing at around ten years of age and reproduce every 3-4 years. When a female is in estrus cycle, she can be conceived only for 3 days in a month. They also have gestation period like that of humans, which extends up to 9 months. The young gorillas weigh around 4 pounds, and the growth rate is twice as fast as human offspring. They all nest in the ground and have the ability to our simple tools like stones and sticks. They are usually quiet animals but use various noises to communicate whenever necessary.
