This characteristic appearance signifies maturity and dominance within a group, known as a troop. Silverbacks play a crucial role in their social structure, often leading and protecting their family members. In addition to their physical traits, silverbacks are known for their strength and intelligence. They are primarily herbivorous, feeding on leaves, stems, and fruits.
