How are worms adapted to habitat in the soil?

Their body is segmented to ensure progress in the soil environment. To move the soil particles apart, they have developed adaptations in the form of a hydroskeleton. There are no special senses, but the sensitive cells in the skin allow the earthworm to feel the touch on its skin and distinguish light from darkness. The mouth is located at the front end of the body. The earthworm feeds on rotting plant debris, which it swallows along with the earth. He can also drag fallen leaves from the surface. Swallowing is done by the muscular pharynx. The food then enters the intestines. Undigested residues, together with the earth, are thrown out through the anus at the posterior end of the body.
