The first part of the book describes all the known phyla of invertebrates with living representatives, together with their component classes. Rather than outline all the anatomical features of differrent types of animals, the book distils those essential characteristics of each group with which the student should be familiar. Lists of diagnostic features permit comparison between the phyla; the diversity of body plans is illustrated by line figures of different forms.
