The mountain gorilla, scientifically known as Gorilla beringei beringei, is one of the most iconic and fascinating animals on the planet. These gentle giants are a subspecies of the eastern gorilla and are found only in the dense forests of the Virunga Mountains, which are shared between Rwanda, Uganda, and the Democratic Republic of Congo. Despite their undeniable beauty and intriguing behavior, the mountain gorilla is critically endangered, with only a few hundred remaining in the wild. In this article, we will delve into the history, evolution, physical description, social structure, distribution, population, behavior, reproduction, diet, predators, threats, and relationship with humans of the mountain gorilla. We will also uncover some fun and incredible facts about these amazing creatures.
Scientific Name and Classification:
The mountain gorilla belongs to the genus Gorilla and is a subspecies of the eastern gorilla (Gorilla beringei). Its scientific name is Gorilla beringei beringei. The eastern gorilla is the largest living primate, and the mountain gorilla is the largest of the four gorilla subspecies.
The mountain gorilla is a great ape and is one of the closest living relatives of humans. They share approximately 98% of their DNA with humans.
Mountain gorillas were first discovered in 1902 by Captain von Berenge in the Virunga Mountains. However, it was not until the 1960s that researchers started to study them in depth. At that time, the population was estimated to be around 400. In the 1970s and 1980s, the mountain gorilla population declined dramatically due to habitat loss, poaching, and civil unrest in the region. In 1981, the mountain gorilla was listed as critically endangered by the International Union for Conservation of Nature (IUCN).
Evolution and Origins:
The common ancestor of humans and gorillas lived around 8-10 million years ago. Over time, humans and gorillas evolved into separate species. The mountain gorilla evolved as a separate subspecies of the eastern gorilla approximately 400,000 years ago.
Mountain gorillas are the largest of the gorilla subspecies, with males weighing up to 400 pounds and females weighing up to 200 pounds. They have long, shaggy black fur that helps them to survive in the cold, wet environment of the mountain forests. They also have a prominent brow ridge, large nostrils, and a sagittal crest on their skull. The sagittal crest is a bony ridge on top of their skull that provides attachment points for their powerful jaw muscles. Mountain gorillas have longer and thicker fur than other gorilla subspecies, which helps them to stay warm in the high-altitude forests where they live.
Mountain gorillas live in groups called troops, which are led by a dominant male called a silverback. The silverback is usually the largest and strongest male in the group and is responsible for protecting the group from predators and other threats. The rest of the group is made up of females, their offspring, and other males. Female mountain gorillas usually leave their natal troop when they reach sexual maturity and join another troop. This helps to prevent inbreeding and promotes genetic diversity within the population.
Anatomy and Appearance:
Mountain gorillas have a distinctive appearance due to their size, long fur, and prominent brow ridge. They have short, powerful legs and long, muscular arms that they use to climb trees and move through the forest. They also have large, powerful hands with opposable thumbs that allow them to grasp objects and manipulate tools. The males are larger and more muscular than the females, and they have a distinctive silver patch of hair on their backs that develops as they mature and become dominant within their troop.
Distribution and Habitat:
Mountain gorillas are found only in the dense forests of the Virunga Mountains, which are shared between Rwanda, Uganda, and the Democratic Republic of Congo. They inhabit the high-altitude forests, ranging from 8,000 to 13,000 feet above sea level. These forests are characterized by dense vegetation, bamboo thickets, and a cool, moist climate. The habitat is critical for the survival of the mountain gorilla, as it provides them with food, shelter, and protection from predators and human threats.
Population – How Many Are Left?:
The mountain gorilla is one of the most endangered animals on the planet, with only around 1,000 individuals remaining in the wild. The population has declined dramatically over the past century due to habitat loss, poaching, and civil unrest in the region. However, thanks to conservation efforts, the population has stabilized in recent years, and there have even been some small increases in certain areas.
Size and Weight:
Male mountain gorillas can weigh up to 400 pounds, while females typically weigh around 200 pounds. They are the largest of the gorilla subspecies, with longer and thicker fur than other gorilla subspecies, which helps them to stay warm in the high-altitude forests where they live.
Behavior and Lifestyle:
Mountain gorillas are gentle and peaceful animals that spend most of their time foraging for food and resting. They are diurnal and spend their days moving through the forest, feeding on vegetation, and interacting with their troop members. They communicate with each other through a variety of vocalizations, including grunts, screams, and chest beats. They also use body language to convey their emotions and intentions, such as hunching their shoulders to appear smaller and less threatening or standing tall to intimidate rivals.
Reproduction, Babies, and Lifespan:
Mountain gorillas reach sexual maturity at around eight years old, and females give birth to their first offspring at around 10-12 years old. The gestation period is around eight and a half months, and females give birth to a single offspring at a time. The babies are born with a full coat of hair and are completely dependent on their mother for the first few years of their life. They are weaned at around three years old but remain close to their mother until they reach sexual maturity. Mountain gorillas can live up to 40-50 years in the wild.
Diet and Prey:
Mountain gorillas are primarily herbivores, and their diet consists of leaves, stems, shoots, fruits, and flowers. They are also known to eat bark, roots, and insects on occasion. They are able to digest tough, fibrous vegetation thanks to their powerful jaws and digestive system, which allows them to extract as much nutrition as possible from their food.
Predators and Threats:
Mountain gorillas have few natural predators in their habitat, as they are at the top of the food chain in their ecosystem. However, they are threatened by human activities, including habitat loss, poaching, and civil unrest in the region. Illegal poaching for bushmeat and the illegal wildlife trade is a major threat to their survival, as is habitat loss due to agriculture, mining, and logging.
Relationship with Humans:
The relationship between mountain gorillas and humans has been fraught with conflict over the years. Historically, humans have hunted gorillas for their meat and body parts, and the destruction of their habitat has been a major threat to their survival. However, in recent years, conservation efforts have helped to protect the remaining mountain gorilla populations, and they have become a major tourist attraction in the region. Gorilla trekking tours have become a popular activity for tourists, providing an opportunity for people to observe these magnificent animals in their natural habitat. Conservation efforts have also focused on working with local communities to reduce human-wildlife conflict and promote sustainable development practices that benefit both people and animals.
- Mountain gorillas are one of the few animals known to use tools in the wild. They have been observed using sticks to test the depth of water before crossing a stream and to probe for food in tree bark.
- The famous primatologist Dian Fossey spent 18 years studying mountain gorillas in Rwanda and was instrumental in their conservation. She was tragically murdered in 1985, and her work inspired the establishment of the Dian Fossey Gorilla Fund International, which continues to work to protect mountain gorillas today.
- Despite their size and strength, mountain gorillas are gentle animals that are rarely aggressive towards humans or other animals. In fact, they are known to be quite playful and affectionate with their troop members.
