With the completion of a single unified classification, the Systema Porifera (SP) and subsequent development of an online species database, the World Porifera In fact, scientists did not even consider animals until about 100 years ago! Sponges belong to Phylum Porifera which includes about 8,000 known species. The demosponges comprise 95% of the world's sponges and include the most colourful species. They range in size from small, encrusting forms, through to Sponges extract nutrition from water pumped through the body. A sponge may filter 10.000 - 20.000 times its own volume every day. Tiny hairs Sponges are aquatic, sessile, benthic, and filter feeding organisms that belong to the animal phylum Porifera. Their body structure is simple, Phylum Porifera is a group of simple animals that includes the sponges. Porifera have no internal organs, nervous tissue, circulatory system, or digestive This page links to photos of marine sponges (Phylum Porifera) we have seen around Kwajalein and other atolls in the Marshall Islands. Sponges are abundant Family Cladorhizidae, comprising the carnivorous sponges, represents a unique innovation within the phylum Porifera. Rather than filter SPONGES: PoriferaNO COMMON NAME (Soleneiscus radovani): ACCOUNTS Source for information on Sponges: Porifera: Grzimek's Following types of canal systems are found in sponges: Ascon type, with flagellated forming the canal system which is a characteristic feature of poriferans. Sponges are animals of the phylum Porifera (play /pɒˈrɪfərə/; meaning "pore bearer"). Their bodies consist of jelly-like mesohyl sandwiched between two thin Sponges (Porifera) are currently considered to be the first branch off the Urmetazoa, common ancestors of all multicellular animals or metazoa. Research in the The scientific name for sponges is "Porifera," which translates into "pore-bearing." A sponge exists pumping water through its body. A sponge is covered with Sponges Most sponges are marine and have skeletons of chalk, glass or a horny material called spongin. Some species should be handled with care as they Sponges, also known as poriferans (Porus = "pore"; ferre = "to bear"), occur in both Since sponges do not have a mouth or gut, the feeding habits of these Article: The systematics of some Jamaican excavating sponges (Porifera).

Project, Shallow water marine sponges The Sponge Barcoding Project is the first worldwide barcoding project on any non-bilaterian taxon and covers the complete taxonomic range of Porifera.

Already with the isolation of the Poriferans are commonly referred to as sponges. An early branching event in the history of animals separated the sponges from other metazoans.
