Gorillas used to be thought of as very aggressive, dangerous animals and films like King Kong did nothing to improve their reputation. However gorillas have been studied and proved to be very gentle and calm. However if he feels threatened a male will stand up and slap his chest with cupped hands whilst roaring. This is just a display intended to frighten away any threat. If this does not work, he will make a bluff charge, rushing towards the intruder but either stopping short or rushing past.
Gorillas spend their days at quite a leisurely pace, eating, resting and playing.
Gorillas walk on all fours keeping their feet flat and their hands in a fist with all the weight resting on the knuckles. Just before it gets dark gorillas make themselves a night nest on the ground by bending over leafy branches to form a comfortable springy platform.
