Description - Systema Porifera by John N.A. Hooper
Phylum porifera is a ecological and economically important group of marine invertebrates, currently a major focus of marine natural product (pharmaceutical) research. Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently the text revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema porifera is unique, making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics.
The book addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Sponges are among the most highly diverse and successful of the aquatic invertebrate phyla, with about 7000 described species and least twice this number extant worldwide. It describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated) Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to many fossil taxa are provided.
