What physical feature signals the full adulthood and leadership status of a mature male Western Gorilla, earning him the title of 'silverback'?

Answer

The saddle of silvery-white hair that develops across their backs around 12 to 13 years of age

The term 'silverback' is a specific physical identifier for a mature adult male Western Gorilla. This designation is earned when the male develops a prominent saddle of silvery-white hair covering his back, typically commencing around 12 to 13 years of age. This silver mantle is an unmistakable visual sign of the male reaching full physical maturity, signifying his established status as the dominant leader of the family group or troop. This development is a key indicator of the male's readiness to assume leadership responsibilities, including protection and decision-making for the entire unit.
