Gorillas are the largest
members of the primate family and are closely related to humans, with
98% of their DNA identical to that of humans. Unlike other primates
they are terrestrial, meaning they do not climb trees and are land
dwelling, inhabiting the tropical rainforests of central Africa.
Historically the gorilla has been portrayed as a vicious killer; however
they are shy gentle creatures that would not attack humans unless
provoked.
Gorillas are classified as mammals, which is defined by the Oxford English dictionary as a ‘Warm-blooded vertebrate animal that has hair or fur, secretes milk, and (typically) bears live young’ (0ED 2010). Upon their discovery gorillas were classified as one species, however they are now separated into two species and four sub species according to geographical location and physical characteristics. They live in groups called a troop lead by a dominant silverback male, and are highly sociable animals, maintaining strong bonds between group members.
In the wild their only predators are leopards, which can attack vulnerable youngsters and the biggest threat to gorillas is man. In recent decades gorilla populations have been affected by habitat loss, disease and poaching. Subsequently all gorilla species are classified as endangered by the International Union for Conservation of Nature (IUCN). Due to the vast dense areas in which they live it is difficult to monitor and protect gorilla populations and therefore difficult to implement successful conservation techniques. However conservation efforts persist and several governmental and non governmental organizations named 2009 the ‘Year of the Gorilla’ with the aim of working together to further improve gorilla conservation.

There are two recognized
gorilla species the Eastern Gorilla and Western Gorilla, defined by the
areas in Africa which they inhabit. Within these classifications are
four subspecies including the Eastern Lowland Gorilla, Mountain Gorilla,
Cross River Gorilla and Western Lowland Gorilla. All subspecies live
in varying habitats, have unique physical characteristics and have
differing populations.

Gorillas are quadrupedal meaning they move around by walking on their knuckles, their huge arms provide balance and support for their large frames. Size and weight varies between species and gender, with males reaching heights of 1.7 m when stood tall and weighing between 170 kg to 240 kg. Females usually weigh between 70 kg to 100 kg and are shorter reaching heights of 1.5 m.
Intelligent, charismatic, and endangered
Gorillas are our closest living relatives after chimpanzees and bonobos. The two gorilla species live in equatorial Africa, separated by about 900km of Congo Basin forest. Each has a lowland and upland subspecies.
Western gorilla:
All four subspecies are either Endangered or Critically Endangered, threatened by hunting for bushmeat, habitat loss, wildlife trade, and infectious diseases. Physical description
The largest living primates, gorillas are stocky animals with broad chests and shoulders, large hands, and forearms that are much shorter than the upper arm. The face is black and hairless, with small eyes that are close together and large, prominent nostrils.
Adult males are identified by a sagittal crest along the midline of the skull and an area of white hair on the back, which is why they are known as ‘silverbacks.’
Eastern gorillas are the larger species, and have darker and longer fur, particularly on their arms. In comparison, western lowland gorillas have shorter hair that is gray or brown with a tendency to red on their heads.
To add to these differences, lighter hair on western silverbacks stretches to their thighs, as opposed to the more defined patch in the otherwise dark backs of eastern gorillas.
Size: Adult males weigh up to 200kg, with females around half this size. Can reach a height of 1.2-1.7 meters when standing on 2 feet.

Size: Adult males weigh up to 200kg, with females around half this size. Can reach a height of 1.2-1.7 meters when standing on 2 feet.
Forest families
Gorillas typically live in the lowland tropical rainforests of Central Africa, although some subspecies are found in montane rainforest (between 1,500 and 3,500 meters) and in bamboo forest (between 2,500 to 3,000 meters).
Social structure
Gorillas have a well-developed social structure, forming stable family groups in which the dominant male keeps his position for years.
Group size is usually 5-10 individuals, but can vary from 2 to over 50 members. According to group size, habitat quality and food availability, a group's home range may vary from 5 to over 30km², with frequent overlap between group ranges.
If a male leaves a group, he wanders alone for a number of years, then sometimes establishes a range next to or overlapping that of his old group.
Adult males that stay in a group are generally the offspring of the dominant male and eventually will take over leadership.
As a general rule, female gorillas leave their group at maturity to join other groups or single males, although cases of females reproducing in their original groups are known.
Life cycle
Females become sexually mature at 7-8 years old, but do not start to breed until several years later. Males mature later than females, with few breeding before the age of 15 years.
High infant mortality, a long gestation (8.5 months), a tendency to single births, and a prolonged period of maternal care mean that, on average, only one baby is reared in a 4-6 year period. Females generally give birth to only three or four surviving young during their reproductive life.
The mortality rate for gorillas less than one year old is high, but for adults the rate is only 5%. In the wild, they might live to be 40 years old. In the United States, a captive gorilla was reported to have lived to the age of 54.
Diet
Gorillas are mainly herbivorous (vegetarian) and spend almost half of the day feeding on stems, bamboo shoots, and a variety of fruits, supplemented with bark and invertebrates.
At some sites, western lowland gorillas have been known to break open termite nests and feed on the larvae.

Population & distribution
Many gorilla populations have declined or completely disappeared over the past few decades.
The lowland subspecies are more numerous and widespread than the upland and mountain subspecies. Mountain gorillas are the only gorillas to show an increase in numbers, but the overall population size is still very low.

The lowland subspecies are more numerous and widespread than the upland and mountain subspecies. Mountain gorillas are the only gorillas to show an increase in numbers, but the overall population size is still very low.
- The western lowland gorilla is the most widespread, possibly numbering 100,000.
- The Cross River gorilla
is currently the world’s rarest great ape, with a population of only
around 250-300 restricted to a small area of highland forest on the
border of Cameroon and Nigeria.
- There is no reliable estimate of the eastern lowland gorilla population; however at one time it could have reached 17,000 individuals.
- The total population of mountain gorillas is around 880 individuals, split into two separate groups.
The
mountain gorilla, a large, strong ape inhabiting Africa’s volcanic
slopes, has few natural predators. Yet due to detrimental human
activity, such as poaching, civil war, and habitat destruction, the
mountain gorilla has become the most endangered type of gorilla, with
only around 700 mountain gorillas living in the world. - See more at:

slopes, has few natural predators. Yet due to detrimental human
activity, such as poaching, civil war, and habitat destruction, the
mountain gorilla has become the most endangered type of gorilla, with
only around 700 mountain gorillas living in the world.
Currently, the mountain gorilla’s habitat is limited to protected national parks in two regions of Africa. One group of gorillas lives in the Bwindi Impenetrable National Park in Uganda. The other group is spread over three national parks in the Virungas mountain region of the Democratic Republic of Congo, Uganda, and Rwanda.
Mountain gorillas are as shy as they are strong. But when threatened, they can be aggressive. They beat their chests and let out angry grunts and roars. Group leaders will charge at the threat. Mothers will fight to the death to protect their young.
Mountain gorillas live in groups of up to 30. The group, or troop, is led by a single alpha male, an older silverback. These males are called silverbacks because of the silver stripe they develop on their backs when they mature. The oldest males of the group are at least 12 years old. These troops also include several younger males, adult and juvenile females, and infants.
In addition to providing protection to group members, silverbacks maintain order and decide all activities within their troop. They schedule feeding trips, resting time, and travel. They also father the majority of the young in the group.
Female mountain gorillas can produce young beginning at age 10. They carry one or two babies at a time and give birth after a 8.5-month gestation period. In general, they will bear between two and six offspring in a lifetime.
Newborn gorillas weigh about 1.8 kg (4 lb.) at birth. They are as weak and uncoordinated as human babies. For the first four years of their lives, they get around by clinging to their mothers backs. By 3.5 years of age, the young gorillas are fully weaned from their mothers milk and start the same diet as mature mountain gorillas: plants, leaves, roots and shoots.
Fully-grown male mountain gorillas can weigh up to 180 kg (400 lb). Females weigh half that at about 90 kg ( 200 lb). Aside from the silver stripe on their backs, male mountain gorillas are distinguished from females because they have a crest of fur on their heads. Both genders have similar thick black hair covering their body. Their thick hair keeps them warm in cold mountain temperatures.

Conservation Status
Mountain gorillas are considered endangered by IUCN’s Red List. Not only are mountain gorillas threatened by loss of habitat due to human encroachment, they have also become victims of human violence. As civil war rages in Africa, efforts to conserve mountain gorilla populations have been curtailed. Mountain gorillas have also been killed or captured by poachers. Their body parts are sold to collectors, and baby gorillas are sold illegally as pets, research subjects, or private zoo animals.- See more at: http://www.animalfactguide.com/animal-facts/mountain-gorilla/#sthash.Bd79GjiT.dpuf

Currently, the mountain gorilla’s habitat is limited to protected national parks in two regions of Africa. One group of gorillas lives in the Bwindi Impenetrable National Park in Uganda. The other group is spread over three national parks in the Virungas mountain region of the Democratic Republic of Congo, Uganda, and Rwanda.
Mountain gorillas are as shy as they are strong. But when threatened, they can be aggressive. They beat their chests and let out angry grunts and roars. Group leaders will charge at the threat. Mothers will fight to the death to protect their young.
Mountain gorillas live in groups of up to 30. The group, or troop, is led by a single alpha male, an older silverback. These males are called silverbacks because of the silver stripe they develop on their backs when they mature. The oldest males of the group are at least 12 years old. These troops also include several younger males, adult and juvenile females, and infants.
In addition to providing protection to group members, silverbacks maintain order and decide all activities within their troop. They schedule feeding trips, resting time, and travel. They also father the majority of the young in the group.
Female mountain gorillas can produce young beginning at age 10. They carry one or two babies at a time and give birth after a 8.5-month gestation period. In general, they will bear between two and six offspring in a lifetime.
Newborn gorillas weigh about 1.8 kg (4 lb.) at birth. They are as weak and uncoordinated as human babies. For the first four years of their lives, they get around by clinging to their mothers backs. By 3.5 years of age, the young gorillas are fully weaned from their mothers milk and start the same diet as mature mountain gorillas: plants, leaves, roots and shoots.
Fully-grown male mountain gorillas can weigh up to 180 kg (400 lb). Females weigh half that at about 90 kg ( 200 lb). Aside from the silver stripe on their backs, male mountain gorillas are distinguished from females because they have a crest of fur on their heads. Both genders have similar thick black hair covering their body. Their thick hair keeps them warm in cold mountain temperatures.

Conservation Status
Mountain gorillas are considered endangered by IUCN’s Red List. Not only are mountain gorillas threatened by loss of habitat due to human encroachment, they have also become victims of human violence. As civil war rages in Africa, efforts to conserve mountain gorilla populations have been curtailed. Mountain gorillas have also been killed or captured by poachers. Their body parts are sold to collectors, and baby gorillas are sold illegally as pets, research subjects, or private zoo animals.- See more at: http://www.animalfactguide.com/animal-facts/mountain-gorilla/#sthash.Bd79GjiT.dpuf
