Non-Chordates are animals that do not have the rod-like structure known as the notochord in their bodies, and are thus classified as such. This phylum contains members of the phyla Porifera as well as members of the phyla Echinodermata, Mollusca, Arthropoda (including the worms), Aschelminthes, Platyhelminthes, Ctenophora, and Coelenterata (which includes the worms). They are all believed to be a part of the non-chordates group of individuals. The present book Diversity of Non-Chordata is comprehensive up-to-date textbook and covers the entire syllabus. This is an indispensable text meeting complete requirements of undergraduate and postgraduate students of Zoology. It has been designed to approach the morphology, anatomy, physiology and development of selected types in a very simple and lucid style.
Emphasizes life cycle pattern of representative genus with well-illustrated diagrams.
