How do the arm length and leg length generally compare in the skeletal build of the Western lowland gorilla?
Answer
Arms generally exceed leg length
The overall robust physique of the Western lowland gorilla features proportionally longer arms compared to their legs. This relationship—arms often exceeding leg length by nearly a foot when standing—is a characteristic shared with primates that are more heavily involved in tree-climbing. Although these gorillas primarily utilize terrestrial locomotion via knuckle-walking, this limb proportion serves as an evolutionary reflection of their more arboreal ancestry. This length difference contributes to their immense power and reach when moving objects or foraging.
