Clathrina
''Clathrina'' is a genus of calcareous sponge in the family Clathrinidae. Several species formerly in ''Clathrina'' were transferred to the newly erected genera ''Arturia'', ''Ernstia'', '' Borojevia'', and '' Brattegardia'' in 2013. The name is derived from the Latin word "''clathratus''" meaning "latticed". Description Species of ''Clathrina'' have a tubular organization as all species of the family Clathrinidae, with the cormus composed of anastomosed tubes. The skeleton contains spicules in the form of triactines and/or tetractines, sometimes with diactines, tripods and tetrapods as well. The choanoderm is usually flat, never forming folds when the sponge is extended. Species There are 68 species assigned to ''Clathrina''. * '' Clathrina angraensis'' Azevedo & Klautau, 2007 * '' Clathrina antofagastensis'' Azevedo, Hajdu, Willenz & Klautau, 2009 * '' Clathrina aphrodita'' Azevedo, Cóndor-Luján, Willenz, Hajdu, Hooker & Klautau, 2015 * '' Clathrina arabica'' (Miklucho ...

Arturia (sponge)
''Arturia'' is a genus of calcareous sponge in the family Clathrinidae which contains 14 species. It is named after Arthur Dendy, a prominent researcher of calcareous sponges. It was renamed ''Arturia'' in 2017 because the name ''Arthuria'' was already assigned to a genus of molluscs. Description and biology Calcinea in which the cormus comprised a typical clathroid body. A stalk may be present. The skeleton contains regular (equiangular and equiradiate) triactines and tetractines. However, tetractines are more rare. Diactines may be added. Asconoid aquiferous system. ''Arturia canariensis'', for example, is a filter feeder, sieving plankton and other organic material out of the current of water as it passes through the ostia. Both asexual reproduction by budding and sexual reproduction take place in ''Arturia canariensis''. As in other species, each sponge is a hermaphrodite. Sperm is liberated into the sea and some is drawn into other sponges with the water current that passes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernstia
''Ernstia'' is a genus of calcareous sponges in the family Clathrinidae. The genus was erected in 2013 to contain five species previously assigned to ''Clathrina''. The genus name honors German naturalist Ernst Haeckel for his contributions towards sponge taxonomy and phylogeny. Species * ''Ernstia adunca'' Fontana, Cóndor-Luján, Azevedo, Pérez & Klautau, 2018 * ''Ernstia arabica'' Voigt, Erpenbeck & Wörheide, 2017 * ''Ernstia chrysops'' Van Soest & De Voogd, 2015 * ''Ernstia citrea'' Azevedo, Padua, Moraes, Rossi, Muricy & Klautau, 2017 * ''Ernstia cordata'' (Haeckel, 1872) * ''Ernstia gracilis'' (Haeckel, 1872) * ''Ernstia indonesiae'' Van Soest & De Voogd, 2015 * ''Ernstia klautauae'' Van Soest & De Voogd, 2015 * ''Ernstia laxa'' (Kirk, 1896) * ''Ernstia minoricensis'' (Lackschewitz, 1886) * ''Ernstia multispiculata'' Azevedo, Padua, Moraes, Rossi, Muricy & Klautau, 2017 * ''Ernstia naturalis'' Van Soest & De Voogd, 2015 * ''Ernstia quadriradiata'' (Klautau & Borojevic, 200 ...

Clathrina Clathrus
''Clathrina clathrus'' is a species of calcareous sponge belonging to the family Clathrinidae. This yellow (occasionally white) sponge, up to 10 cm in diameter, usually appears cushion-shaped at a distance (its close relative '' Clathrina coriacea'' is normally flatter in appearance). Close-up the sponge can be seen to consist of a tangled mass of tubes (these tubes are thicker and less tightly knit than in ''C. coriacea'' and there is no osculum as found in that species). Like ''C. coriacea'', the spicules are exclusively three-pointed ''triactines''. This is a shallow-water species found in the Mediterranean and on Atlantic coasts of Europe as far north as the British Isles The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, ....

Clathrinida
The Clathrinida are an order of calcareous sponges found in marine environments. These sponges have an asconoid structure and lack a true dermal membrane or cortex. The spongocoel is lined with choanocytes Choanocytes (also known as "collar cells") are cells that line the interior of asconoid, syconoid and leuconoid body types of sponges that contain a central flagellum, or ''cilium,'' surrounded by a collar of microvilli which are connected by a t ....

Brattegardia
''Brattegardia'' is a monotypic genus of calcareous sponge with a single species: ''Brattegardia nanseni'' from Norway. The genus is named after the Norwegian marine biologist Torleiv Brattegard. The species is named after Norwegian helminthologist Fridtjof Nansen. Description Calcinea in which the cormus is formed by anastomosed tubes covered by a thin membranous layer, at least in young specimens. Cormus is massive/globular with or without a stalk. The skeleton contains regular (equiangular and equiradiant) triactines and tetractines, but parasagittal triactines may be present. Triactines are the most numerous spicules. Aquiferous system asconoid. See also * 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 t ... References Clathrinidae Sponge genera [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Calcareous Sponges
The calcareous sponges of class Calcarea are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate in the form of calcite or aragonite. While the spicules in most species have three points, in some species they have either two or four points. Biology All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans are represented within class Calcarea : asconoid, syconoid, and leuconoid. Typically, calcareous sponges are small, measuring less than in height, and drab in colour. However, a few brightly coloured species are also known. Calcareous sponges vary from radially symmetrical vase-shaped body types to colonies made up of a meshwork of thin tubes, or irregular massive forms. The skeleton has either a mesh or honeycomb structure. Classific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
