On the basis of presence and absence of notochord, the animal kingdom has been classified into two sub kingdom: 1. Classification of Chordates. Larve are glochidium or trocophore (veliger).. All are marine. These two phyla therefore have an enormous impact on the health and economy of humans. Non chordata includes a number of phyla.The major ones are Porifera, Coelenterata, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca and Echinodermata. In order, they are: domain, kingdom, phylum, class, order, family, genus, and species. 3. What are the changes within a chosen range in the external environment of a living system? They are unicellular, jelly-like protozoa found in fresh or sea water and in moist soil.
