Crayfish can hear, but they do not have ears, so they do not hear in the usual sense. Our ears pick up vibrations via the eardrum and tiny bones in our ears, but crayfish have thousands of sensory bristles. Some of these sensory bristles respond to chemicals, others to touch, but either way, they enable te crayfish to not only hear, but also to smell and feel.
