A type of worm with many linked sections is a flatworm.?

Actually, a type of worm with many linked sections is called an annelid, not a flatworm. Annelids, such as earthworms and leeches, have segmented bodies composed of many linked sections. Flatworms, on the other hand, belong to the phylum Platyhelminthes and have a flattened, unsegmented body structure.
