Gorillas are gentle giants with human-like emotions like laughing and grief.
Gorillas, along with chimpanzees and bonobos, are our closest relatives.
Gorillas, the largest great apes, have massive hands, and small eyes in hairless faces.
Gorillas reside in family groups of five to 10, but sometimes two to more than 50.
After breeding, a female will have one child every four to six years and three or four in her lifetime.
Gorillas' low reproduction rate makes population recovery challenging.
By the mid-2020s, a 2010 UN research says they may disappear from large portions of the Congo Basin.
