Gorilla Gorilla
Western Gorilla
Tropical and subtropical forests
The Western Gorilla, gorilla gorilla, stands as a majestic primate, recognized by its dense, dark fur and a more prominent ridge along its brow compared to its Eastern counterpart. Adult males, known as silverbacks due to the distinctive silver-gray fur on their backs that develops with age, can reach heights of up to 1.8 meters (6 feet) when standing and weigh between 140 to 200 kilograms (310 to 440 pounds). Females are significantly smaller, highlighting the species' pronounced sexual dimorphism. Their expressive faces, complete with deep-set eyes and a broad nose, contribute to their emotive appearance, allowing for strong social bonds within groups.

| Average Weight: | Males: 140-200 kg, Females: 70-100 kg |
| Average Length: | Males: 1.5-1.8 m tall when standing upright, Females: slightly shorter |
| Lifespan: | 35-40 years in the wild, longer in captivity |
| Diet: | Primarily vegetarian diet including leaves, shoots, roots, and fruit |
| Conservation Status: | Critically Endangered (CR) |
Western Gorillas lead a largely terrestrial lifestyle, spending considerable time on the ground within their forest habitats in Central Africa, although they are capable climbers as well. Living in groups called troops, typically consisting of one dominant silverback, several females, and their offspring, these gorillas have a complex social structure that emphasizes cooperation and stability. They have home ranges but are not territorial, moving daily through the forest in search of food. Their day is structured around feeding in the morning, resting around midday, and then feeding again in the late afternoon before nesting in leaves on the ground or in trees at night.
The diet of Western Gorilla is predominantly herbivorous, focusing on leaves, stems, fruits, and occasionally small insects like termites and ants. This varied diet is crucial for their health, providing necessary nutrients and aiding in the digestion process. Their role as seed dispersers contributes significantly to the health of their ecosystem, promoting forest regeneration. The ability to process fibrous plant material is facilitated by their strong jaws and large molars, which grind the vegetation efficiently.
Mating can occur at any time of the year for Western Gorillas, with no specific breeding season. The silverback has exclusive mating rights with the females in his group. Gestation lasts about 8.5 months, leading to the birth of a single infant, which is highly dependent on its mother for the first several years of life. This close bond ensures the young gorilla's survival through constant care and socialization within the troop. As they reach maturity, males may leave to form their own groups, while females often stay within the troop.
Western Gorilla populations are currently classified as Critically Endangered, facing significant threats from habitat destruction, poaching, and diseases like Ebola. Conservation efforts are in place, aiming to protect their natural habitats and reduce human-induced threats. Despite these efforts, their numbers continue to decline, highlighting the urgent need for increased conservation measures to ensure the survival of this remarkable species.
