Which worm has a body that is made of many ring-like parts?

The worm with a body made of many ring-like parts is the annelid worm, commonly known as earthworms. Annelids are characterized by their segmented bodies, which consist of multiple repeating units called segments, giving them a ring-like appearance. This segmentation aids in movement and allows for greater flexibility compared to non-segmented worms. Other examples of annelids include leeches and marine polychaetes.
