Do gorillas fight frequently?

Because of their sharp canines and great strength, gorilla males are very dangerous opponents when they are in a fighting mood. Therefore, most differences of opinion are not resolved by fighting, but by displaying and other threat behaviour patterns, without anyone getting injured. Gorillas are famous for their display behaviour culminating in the chest beating and loud hooting. The chestbeat sounds especially impressive in silverback males.

Severe aggression is rare in stable gorilla groups, but when two groups meet, the leading silverbacks can sometimes engage in a fight to the death, mainly using their sharp canines to cause deep, gaping injuries.
