Fewer than 400 are left in the wild. Poaching and war present the greatest threats to these creatures. The largest of the apes, the Mountain Gorilla is a highly intelligent and gentle creature. Despite a ferocious reputation, the gorilla rarely makes use of his incredible strength. Gorillas spend almost all of their day on the forest floor in small family groups eating leaves and stems of trees, and take a nap at midday.
Young gorillas climb a lot, though.
Gorillas don't move around much, and even make their nests right on the ground. Male gorillas beat their chests to show great strength to the other guys.
