He moved like lightning. It was devastating. This is wrong the Eastern lowland Gorilla averages lbs in Wild Males and can exceed lbs in the Wild. Your email address will not be published.

Where does an pound gorilla sleep? Compared to other subspecies, western lowland gorillas have a more pronounced brow ridge and ears that appear small in relation to their heads. They also have a differently shaped nose and lip than other subspecies.
Adult male gorillas' heads look conical due to the large bony crests on the top and back of the skull. These crests anchor the massive muscles used to support and operate their large jaws and teeth. Adult female gorillas also have these crests, but they are much less pronounced. In comparison to the mountain gorilla, the western lowland gorilla has a wider and larger skull, and their big toe is spread apart more from the alignment of the other four toes.
Gorillas' arms are longer than their legs; when they move on all fours, they knuckle-walk, supporting their weight on the third and fourth digits of their curled hands. Like other primates, each individual has distinctive fingerprints. Gorillas also have unique nose prints. Males are much larger than females.
Adult males weigh an average of pounds They stand up to 6 feet 1. Adult females weigh from to pounds Adult males have an arm span of 8 feet 2. Western lowland gorillas are broadly distributed across the Congo Basin, and are more or less continuously distributed across the countries of Gabon, Central Africa Republic, Cameroon, Angola, Equatorial Guinea, and Congo.
Though present historically in the Democratic Republic of Congo, they are now likely extinct there. Western lowland gorilla ranges have been measured from 9 to 14 square miles The average distance traveled in a day is usually less than 1 mile 1. Because of their large size, gorillas spend most of their time on the ground. Gorillas communicate using auditory signals, visual signals and odors. They are generally quiet animals but they may also scream, bark and roar.
Scientists have heard up to 22 different gorilla vocalizations, each seeming to have its own meaning. Some examples of gorilla "body language" include crouching low and approaching from the side when being submissive; walking directly when confident and standing, slapping their chests and advancing when aggressive.
Gorillas are primarily herbivorous, eating the leaves and stems of herbs, shrubs and vines. They also eat the fleshy fruits of close to a hundred seasonally fruiting tree species. Other gorilla subspecies eat proportionally less fruit. Gorillas get some protein from invertebrates found on leaves and fruits. Adult male gorillas eat about 45 pounds 32 kilograms of food per day. Females eat about two-thirds of that amount.
At the Smithsonian's National Zoo, the group is fed together in the morning. Food items are cut up and spread over a wide area.
In the summer, this is usually done in the yard. In the afternoon, individuals are separated so each animal gets its share of preferred food items. Morning and evening foods include chow, greens, fruits and vegetables.
Forage items placed in hay for the gorillas include popcorn, sunflower seeds, peanuts, "enrich bits," beans and diced fruits and vegetables. Fresh tree trimmings are given daily. Some of the gorillas favorite browse; options are Bradford pear, willow, mulberry with berries and maple.
There are three feeding behaviors sometimes observed in gorillas in human care that can bother visitors. These behaviors are natural, though not to humans. They are regurgitation and reingestion, coprophagy eating feces and urine drinking.
Regurgitation and reingestion involves an animal regurgitating some of its food and re-eating it. Biologists do not entirely understand why gorillas exhibit this behavior in human care.
A few ideas include starch or sugar content, mineral recapture or the food tasting good. Provision of forage foods, increased smaller feedings and providing browse seem to reduce this behavior in some individuals. Coprophagy is seen in the wild and is defined as the eating of feces. Gorillas do not have very efficient digestive systems for a high fiber diet, so unprocessed food can be found in their feces.
Coprophagy allows an animal to utilize this food. Similarly, urine drinking might be explained as the recollection of minerals. Gorillas are flexible in their nature and behavior. Thus, the information found here is only a general guide.
Gorillas live in groups, or troops, from two to over 30 members. But data seems to indicate that western lowland gorillas live in smaller groups, averaging about five individuals. Groups are generally composed of a silverback male, one or more black back males, several adult females and their infant and juvenile offspring.
This group composition varies greatly due to births, deaths and the immigration and emigration of individuals. Mature offspring typically leave their birth group to find a mate. At about eight years old, females generally emigrate into a new group of their choosing.
They seem to choose which silverback to join based on such attributes as size and quality of his home range. A female may change family groups a number of times throughout her life. When leaving their birth group, some sexually mature males may attempt to replace the silverback in an already established group. However, they usually spend a few years as bachelor males. Nevertheless, a new troop can be easily formed when one or more non-related females join a lone male. A gorilla can use its feet to grab.
The bones and muscles of gorillas and humans are similar but the body shape is different. Gorilla groups can be composed of different social forms. At night they build nests for sleeping, sometimes in trees, sometimes on the ground.
They are methodical in search of food and they are smart enough to remember when and where the most desirable food ripens. They savor their meals, smacking lips together and grumbling with contentment.
A baby gorilla may weigh only 4. A male gorilla can weigh twice as much as a female. The faces of gorillas are different from one another, just like humans. Gorillas are gentle animals.
