The Mountain Gorilla endures high altitudes within the cloud forests of three national parks, spanning across the Virunga volcanic mountains and extending its reach into one of Uganda's national parks. This species inhabits zones climbing up to 7,200 to 14,100 feet.

Unlike other types of gorillas, the Mountain Gorilla possesses thicker, longer fur designed to withstand colder climates inherent in its environment. 

Despite being smaller than the Eastern Lowland Gorilla, adult male gorillas demonstrate distinctive bony crests atop and at the back of their skulls, giving them a conical appearance. These crests also anchor their powerful jaw muscles.

Starting in 1967, Dian Fossey dedicated 18 years to a detailed study of mountain gorillas. She brought new findings to light, implemented accurate counts, and introduced helpful conservation methods, like anti-poaching patrols. Her work continues through the Dian Fossey Gorilla Fund International, protecting Virunga's mountain gorillas.

Similarities in genetic makeup to humans expose mountain gorillas to human diseases2. An immune system ill-developed against such diseases results in respiratory infections, accounting for approximately 20% of sudden deaths among these gorillas.
