Like the other apes (gibbons,gorillas,and orangutans),they have not tail. The chimp's hand and feet are much like yours,expect their big toes turn out to help them grasp limbs to climb better. Their eyes,ears,nose,and other sense organs work much the same as yours. They often walk using the knuckles on the back of their hands to support their upper body weight. However,they can walk and run just like we do when they are carrying things or get excited and want to see further. Their ability to change facial expressions to show feelings resembles humans,too. They are the only other animals that can recognize themselves and make faces in a mirror.
