Earthworms feed themselves by making their way through the soil. They do this by pulling soil into their mouth with their prostomium, (the first body segment of a worm excluding the mouth) combined with the muscular pharyngeal that is located on either side of the pharynx which causes the worm to actually suck in its food at a very high suction pressure. This is exactly why earthworms do not have eyes, food catching structures, or head appendages (includes nose and ears) . Earthworms also dont need ears because they have the senses that help them feel vibration in the soil. Their bodies have never needed to create such structures due to their natural way of moving and eating food. The food then enters the digestive system.
