Question

How does the earthworm move

Answer 1

Earthworms are adapted for life underground. Their streamlined shape allows them to burrow through soil. They have no skeletons or other rigid structures to interfere with their movement. The earthworm’s body is divided into segments. Each segment has a number of setae or very small bristles that earthworms use to help them grip the soil as they move.
