Answer:
Each segment has a number of setae or very small bristles that earthworms use to help them grip the soil as they move. ... The earthworm withdraws the front setae and uses its rear setae to anchor itself at the back. The earthworm uses its circular muscles to lengthen and push itself forward again.
