| | Animal Phyla |
 | | Ctenophores superficially resemble miniature medusae (phylum Cnidaria); however, most medusae arise asexually from a polyp generation and ctenophores have no polyp stage in their life cycle. | | | Having at some stage of development an axial rod-like notocord for support of the body; chordates also have a single dorsal tubular nerve cord, paired gill slits between the pharynx and exterior, and a tail behind the anus; subdivided into three major subphyla: Subphylum Urochordata (tunicates); Subphylum Cephalochordata (lancelets); and Subphylum Vertebrata (vertebrates). | | | Peanut worms (phylum Sipunculoidea) are named after their shape when when fully contracted, such as when they are handled. |

| | Biological Diversity 7 |
| | The phylum as a whole has adult bilateral symmetry and cephalization (the development of a head with sensory organs, in most members). | | | Cladistic analysis by J. Reitner in 1990 suggests archaeocyathids are properly placed in the Phylum Porifera instead of having their own phylum. | | | This phylum is included as the oranisms are also triploblastic. |

| | Phylum Nemata |
| | While nematodes are generally accepted as being a phylum, debate is still ongoing concerning their relationship to other animals grouped together on the basis of the structure of the body cavity. | | | Cobb also placed nematodes in their own phylum, the phylum Nemata. | | | When a reference is made to Nemata, there is no doubt that it is the phylum being referred to whereas when an author makes a reference to Nematoda, the author could mean either the phylum or the class. |

| | Occasionally, however, different body plans are not assigned different phyla and this creates an appearance that phyla can't evolve. | | | There are a couple of cautions about the use of the term phyla. | | | Before we can discuss phylum level evolution, we must know what a phylum is. A phylum is a group of animals sharing a similar body plan. |
