Plus the 2-3 little hairs that they have in the mouth (more towards the center) they act like a detectors, if they get touched about 0 to 3 times, the plant thinks its probably some leaf or dirt speck or something nothing alive/good to eat, but if it detects 3 or more touches it starts closing its "mouth", then again when it closes it waits a little bit for movement/resistance to confirm that it caught something alive so no jasmonic acid which it uses for braking down food is wasted
