Sponges are an ancient group of invertebrate animals whose basic body plan has remained unchanged for millions of years. There are no distinct organs or tissues, digestion is intracellular with excretion and respiration being by diffusion. The classification of sponges presents many problems because they share very few characteristics with other animals. Some zoologists consider them to be outside the line of evolution which led to other animals, the metazoans. Consequently, sponges may be labeled as parazoans. This essential reference provides a complete list of all the known species of sponges (up to the end of 2007), along with a key to their synonyms. At the front of the book there is an outline classification to guide you to the location of unfamiliar species, followed by a synopsis of the phylum. This is followed by the checklist and synonym key. At the end of the book is an outline classification of the animal kingdom, and a brief bibliography.

Download Systema Porifera Book in PDF, ePub and Kindle
Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera 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. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera 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 all recent and many fossil taxa are provided.
