(iii) Silverback gorilla, "Nearly got it," by Oliver Dreike, Rwanda
Gorilla https://en.wikipedia.org/wiki/Gorilla
(The eponymous genus Gorilla is divided into two species: the eastern gorillas and the western gorillas; section 1 Etymology; Adult male gorillas are known as silverbacks due to the characteristic silver hair on their backs reaching to the hips)
Quote: "The silverback is the center of the troop's attention, making all the decisions, mediating conflicts, determining the movements of the group, leading the others to feeding sites, and taking responsibility for the safety and well-being of the troop. Younger males subordinate to the silverback, known as blackbacks, may serve as backup protection. Blackbacks are aged between 8 and 12 years and lack the silver back hair.
