Question

Quizplus · Accepted Answer

Earthworms crawl by using peristalsis, which is the contraction and relaxation of their muscles in a wave-like motion to move themselves forward. They do not have legs or scales on their belly to assist in movement, and simply pushing themselves from the tail would not provide efficient movement. Undulating from side to side is not an accurate description of how earthworms move.
