The worm would be unable to burrow and dig through the soil.
Chaetae are involved in the locomotion of the worm by giving the worm grip and <span>tools</span> to burrow <span>through</span>

Sickle cell anemia is a genetic condition that distorts the shape of the hemoglobin. This reduces the capacity of the red blood cells to carry oxygen. Another effect is that the distorted red blood cells come together forming a heavy and compact collection of cells that can block the flow of blood. The sedimentation rate is increased by sickle cell anemia.
