These are the following phyla:
Nematoda: The members of this phylum possess a false body cavity (pseudocoelom) between the mesoderm and the endoderm.
Echinodermata: Echinoderms can carry out respiration, excretion, and locomotion with the help of a water driven system of tubes and canals.
Arthropoda: Phylum arthropoda (arthrus: joint; pod: foot) hosts many organisms such as insects, crustaceans, and arachnids; all of which show jointed appendages .
Porifera: As the name suggests, organisms in this phylum are extremely porous. Each of these pores leads to a canal system, lined by specialized cells called choanocytes (collar cells).
Protochordata: This phylum shows organisms which possess a primitive notochord (proto: primitive; chord: notochord) in certain stages of their life.
