What things help a worm survive in soil?

The worm had a torpedo shaped head that allows movement through the dirt. It's almost microscopic ribs all along it's body all act like a separate foot pulling the worm in any direction it needs to go. The mucus that the worm secretes from it's body pacts the dirt to make tunnels, gives the worm an extra layer of protection, and makes it easier to slide within the tunnels it creates. Because of the mucus, the worm can move faster underground than if it was above surface. The worm's mouth is at the very tip of the torpedo shaped head so that in travel, the worm can also consume it's meal. The long body of the worm is filled with one large intestine and multiple hearts. Once the dirt is inside the worm's intestine, the nutrients are extracted as the dirt reaches the worm's anus and leaves the worm's body. All of these descriptions of the worm and the functions it's body has are adaptions the worm has so it can live in soil.
