Cladorhiza Inversa
''Cladorhiza inversa'' is a species of sponge in the taxonomic class Demospongiae. The body of the sponge consists of a spicule and fibers and is water absorbent. The scientific name of this species was first published in 1886 by Ridley & Dendy.van Soest, R. (2011). ''Cladorhiza inversa'' Ridley & Dendy, 1886.

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Demospongiae
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order (Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are over ac ...

Spicule (sponge)
Spicules are structural elements found in most Sea sponge, sponges. The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators. Sponge spicules are made of calcium carbonate or Silicon dioxide, silica. Large spicules visible to the naked eye are referred to as megascleres, while smaller, microscopic ones are termed microscleres. The composition, size, and shape of spicules are major characters in sponge systematics and Taxonomy (biology), taxonomy. Overview Sponges are a species-rich clade of the earliest-diverging (most Basal (phylogenetics), basal) animals. They are distributed globally, with diverse ecologies and functions, and a record spanning at least the entire Phanerozoic. Most sponges produce skeletons formed by spicules, structural elements that develop in a wide variety of sizes and three dimensional shapes. Among the four sub-clades of Porifera, three (Demospongiae, Hexactinelli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Cladorhizidae
Cladorhizidae is a family of demosponges which are carnivorous and prey on crustaceans and other small animals. They are deep sea sponges typically found on oceanic ridges and seamount systems. As of 2017, nine new species have been discovered in the Southwest Indian Ocean Ridge (SWIOR) including: ''Abyssocladia boletiphora'', ''Ab. corniculiphora'', ''Ab. hemiradiata'', ''Asbestopluma (Asbestopluma) unguiferata'', ''As. (A.) jamescooki'', ''As. (A.) laminachela'', ''As. (A.) pseudoisochela'', ''As. (A.) ramuscula'' and ''Chondrocladia (Meliiderma) rogersi.'' These discoveries have proven to show that this family of unique sponges is much more diverse than originally known. Genera The World Register of Marine Species includes the following genera: *''Abyssocladia'' Lévi, 1964 *'' Abyssosdiskos'' Ekins, Erpenbeck, Goudie & Hooper, 2020 *''Asbestopluma'' Topsent, 1901 *''Axoniderma'' Ridley & Dendy, 1886 *'' Bathytentacular'' Ekins, Erpenbeck, Goudie & Hooper, 2020 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
