Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSystema Porifera\u003c\/strong\u003e 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. \u003cstrong\u003eSystema Porifera\u003c\/strong\u003e addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSystema Porifera\u003c\/strong\u003e 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. \u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2013-08-11\u003c\/p\u003e \u003cp\u003eFormat: SA\u003c\/p\u003e \u003cp\u003e ISBN-10: 9781461352228\u003c\/p\u003e \u003cp\u003eISBN-13: 9781461352228\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-1-4615-0747-5\u003c\/p\u003e \u003cp\u003eDimensions: 279cm x210cm\u003c\/p\u003e \u003cp\u003ePages: 1707\u003c\/p\u003e ","brand":"Springer","offers":[{"title":"Default Title","offer_id":44340555677836,"sku":"9781461352228","price":1260.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9781461352228_3a67dcef-73a3-4058-afb6-dd12e23b7105.jpg?v=1755044355","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9781461352228","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
