Maybe it’s just me but I find chimpanzee mouths to be pretty captivating. Not only are they particularly expressive but they are also exceptionally useful. Chimpanzees have prehensile lips which Debbie described beautifully in this past blog post. That means that mouths are just as good, if not even better than, hands and fingers for tool use and object manipulation. In fact, it can be downright splendid to watch the chimpanzees use their lips with such precision and finesse whether it’s for exploration, grooming, play, or food related.
