Silverback gorillas, sexually mature males with silvery-white hair, are powerful and exceptionally large. They preside over family groups called troops. Gorillas have a complex communication system, using facial expressions, chest-beating and vocalizations to communicate with each other. Like humans having unique and individualized finger prints, gorillas have unique and individualized nose prints!
Silverback gorillas (males) can reach a body weight of nearly 400 pounds. Whereas females may weigh up to 150 pounds.
Western lowland gorillas are recorded to live between 40-50 years of age under human care.
Native to equatorial Africa, gorillas live in lowlands, swamps and forests.
