A sponge, an earthworm, a starfish and a tiger are all animals, yet they share almost nothing at first sight. Zoologists sort more than a million kinds of animals by a few features of the body. In this chapter you learn those features, then meet each phylum in turn, from the sponges to the chordates, and the classes of vertebrates. Python builds a key that names an animal's phylum from its features.

Animals Without a Backbone
The non-chordate phyla, from Porifera to Hemichordata: sponges, cnidarians, comb jellies, flatworms, roundworms, annelids, arthropods, molluscs and echinoderms.
