A earthworm does not have a skeleton. It has bristles on each segment called setae that help the earthworm move. Earthworms have no limbs. The earthworm has two sets of muscles; one that makes it long and thin and one that makes it fat.t eats dirt, digesting the plant and animal matter in the dirt and then eliminates the rest. It has an esophagus for the food to go down, a crop to store the food in, a gizzard that grinds the food down, intestines for the food to pass through and take out nutrients and an anus for the food to come out.
Typically only a few inches (7 or 8 centimeters) in length, some members of this species have been known to grow to a serpentine 14 inches (35 centimeters). Earthwormsâ bodies are made up of ring-like segments called annuli. These segments are covered in setae, or small bristles, which the worm uses to move and burrow.Night crawlers are so named because they are usually seen feeding above ground at night.They burrow during the dayâtypically keeping close to the surfaceâcapable of digging down as deep as 6.5 feet (2 meters).hese segments are covered in setae, or small bristles, which the worm uses to move and burrow.
