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>
the soil. <span> </span>Chaetae <span>are</span> made of chitin project from the body wall <span>on</span> each segment are arranged in 4 pairs and are
sited on the ventral surface - two pairs of ventral chaetae are found just
either side of the midventral line and two pairs are further out in the
ventrolateral position (that is just ventral of the side of the worm).
