Male Silverback gorillas gain the silver tinge on their back when they reach adulthood, usually when they are about 13 years old. They are considered to be mountain gorillas and are distinguished from their lowland cousins by certain traits; they are a little bit bigger, have longer hair and shorter arms than lowland gorilla. Gorillas can climb trees but they are usually found on the ground. Troops or bands are normally led by one dominant male gorilla who will aggressively defend his position through demonstrations of physical power. The band leader also organizes the troop activities like eating, nesting, and their movement. Female Gorillas give birth to one infant at a time after nine months of pregnancy. Baby gorillas ride on their mothers’ back for the first 2-3 years of their lives. Gorillas in captivity have displayed significant intelligence and have even been able to learn basic sign language.
