These animals are without a backbone. Locomotion in nematodes occurs through undulating waves of contraction and relaxation. Cnidarians contain specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts (stingers). Animal phyla are also traditionally defined by the fact that all members of the phylum share a number of distinct morphological features, which are known as the body plan of that phylum. Non chordata, includes a number of phyla: Phylum Porifera, Phylum Coelenerata, Phylum Platyhelminthes, Phylum Aschelminthes, Phylum Annelida, Phylum Arthropoda, Phylum Mollusca and Phylum Echinodermata.
