The largest phyla in kingdom animalia are phylums: Mollusca, Porifera, Cindaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata, our own phylum. PHYLUM NEMATODA: Phylum nematoda consists of only roundworms, some that are parasitic.
This phylum is regarded as the largest phylum of Kingdom Animalia. They include the insects, arachnids, myriapods, and crustaceans. They are generally characterized by the following features: (1) a hard chitinous exoskeleton, (2) segmentation, (3) multiple jointed (paired) appendages, and (4) open circulatory system. The arthropods have an exoskeleton, which is a hard outer casing used to protect their soft internal organs.
