The table matches phyla of the animal kingdom with their respective unique features. Phylum Porifera (sponges) have a unique canal system which is involved in all the major functions of the animal, including feeding, transport of gases, transport of gametes etc. Phylum Ctenophora includes animals commonly known as comb jellies. They generally have eight rows of ciliated comb plates, which help in locomotion. The segmented worms belong to Phylum Annelida, and they apparently exhibit segmentation or metamerism, by which the body is divided into identical segments or metameres. Phylum Arthropoda has the unique feature of jointed appendages (arthros = joint, poda = appendage/leg). Phylum Echinodermata includes animals like the starfish, which have a unique water vascular system which helps in
locomotion, capture and transport of food and respiration.
