The animals thus associated, the Rotifera, Annelida and Arthropoda, are composed of a larger or smaller number of hollow rings, each ring possessing typically a pair of hollow lateral appendages, moved by intrinsic muscles and penetrated by blood-spaces.

The Articulata hypothesis, simply stated, is the phylogenetic grouping of the phylum Annelida, ( which includes polychaetes, oligochaetes, and leeches ), together with the phylum Arthropoda, ( arachnids, insects and crustaceans ) into the common taxon Articulata.

These are flatworms ( platyhelminthes ), namely cestodes ( tapeworms ) and trematodes ( flukes ), and roundworms or nemathelminths ( nematodes ) both of these are parasitic worm types and the annelida, which are not parasitic or at the most ectoparasites like the leeches.

""'Erinaceusyllis cirripapillata " "'is a species belonging to the phylum Annelida, a group known as the segmented worms . " E . cirripapillata " is characterized by its papillae on its dorsal cirri, one of them being distinctively mushroom-shaped.

""'Erinaceusyllis kathrynae " "'is a species belonging to the phylum Annelida, a group known as the segmented worms . " E . kathrynaen " is similar to " E . cirripapillata ", but lacks characteristic papillae on its cirri.
