Each segment in the earthworm contain bristly hairs known as setae that helps the earthworm to move through the soil. It also has streamlined body that helps it to live in narrow burrows. The bristles or setae help anchor and control the worm when moving through soil. The bristles hold a section of the worm firmly into the ground while the other part of the body protrudes forward.
