Earthworms belong to the phylum Annelida, which are characterized by having soft, flexible bodies. Unlike organisms with exoskeletons, such as insects or crustaceans, earthworms have a hydrostatic skeleton that allows them to move and burrow through soil efficiently. The lack of a hard outer covering like an exoskeleton enables earthworms to navigate through narrow spaces and absorb nutrients through their skin.
