Silverbacks develop massive sagittal crests on their skulls to anchor powerful jaw muscles.
Male mountain gorillas exhibit extreme sexual dimorphism, with dominant silverbacks often weighing more than twice as much as adult females. A mature male can exceed 400 pounds, while females typically weigh around 150 to 200 pounds. This size disparity reinforces physical dominance and territorial defense roles. Larger mass increases deterrence during confrontations with rival males. Such pronounced dimorphism is rare among primates of comparable intelligence. Power imbalance shapes social structure directly through biology.

The energy required to sustain a 400-pound herbivore in mountainous terrain is immense. Sexual dimorphism intensifies ecological demand within a troop. Yet the same mass provides protection against predators and rivals. Evolution favored scale despite caloric cost.
In shrinking habitats, supporting extremely large males becomes increasingly resource-dependent. Nutritional stress could influence body condition and dominance stability. The dramatic size gap that defines their society also amplifies vulnerability to habitat degradation. Leadership here is measured in pounds.
