Clathrina Clathrus Scarpone 055
''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 ...

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, ....

Clathrina Cribrata
''Clathrina cribrata'' is a species of calcareous sponge in the family Clathrinidae. The holotype was collected from Kristiansund Kristiansund (, ; historically spelled Christianssund and earlier named Fosna) is a municipality on the western coast of Norway in the Nordmøre district of Møre og Romsdal county. The administrative center of the municipality is the town of ..., Norway. Description ''Clathrina cribrata'' is a massive species with its body formed from a network of large, irregular tubes. Some of these extend above the main body of the sponge as blind tubes and others are open-ended, serving as osculi. This sponge contains only one type of calcareous spicule. These are three-rayed spicules, known as triactines, and are distributed throughout the tissues in an unorganized way.

Clathrina Coriacea
''Clathrina coriacea'' is a species of calcareous sponge belonging to the class Calcarea and family Clathrinidae. Species in the genus Clathrina are composed of calcium carbonate tube-like skeletons containing spicules. The sponge can be located in shallow waters widely distributed along North Atlantic coasts, as well as on other coasts. Anatomy This three-dimensional calcareous sponge species occurs as flat white or yellow encrustations and can also be found with grey, pale rose or orange colors. The sponge ranges from 1 cm to 3 cm in diameter with a central osculum and close inspection reveals a tightly-knit latticework of tubes. The calcareous spicules are all of a similar shape, three-rayed ''triactines.'' The equiangular triradiate spicules have spicule ray junctions that are planar with large dimensions. The tight tubes form a delicate common oscule and the skeleton is made of the calcareous spicules. At younger ages the species are thin and when mature they are soft wi ...

The species name refers to the cone-shaped appearance of the triactines. Description Cormus formed of large, irregular and loosely anastomosed tubes, white in life and beige when preserved. Water-collecting tubes are absent. The skeleton is composed only of triactines without any special organisation. They are equiradiate and equiangular. Actines are conical and straight with blunt tips. ReferencesWorld Register of Marine Species entry Clathrina Fauna of Brazil Animals described in 2001 {{calcarea-stub ...

They are characterized by spicules made of calcium carbonate in the form of calcite or aragonite. While the spicules in most species hav ... from India. The name refers to the clear, bright surface of the sponge. Description Small, flat but not tubular and has meshes consisting of a network of thin walled tubes which are a compact mass attached directly to the substrate. The surface cormus comprises tightly-knit tubes, several tubes joining to share one common oscule, slightly raised above the surface. There are no erect free branches. Cells with granules have not been observed. The skeleton comprises two size-classes of equiangular and equiradiate triactines. Actines are conical and straight, with a sharp tip. The large triactines are situated only in the external tubes, delimiting the cormus, while the smaller tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clathrina Chrysea
''Clathrina chrysea'' is a species of calcareous sponge from New Caledonia. The species epithet refers to the light yellow colour of the sponge. Description Cormus formed of thin, regularly anastomosed tubes. There are no water-collecting tubes. The skeleton of the tubes has no special organisation, comprising a thin meshwork of equiangular and equiradiate triactines. Actines are straight and conical, with a sharp distal tip. They are slightly undulated at the tip. Biochemical studies separated ''Clathrina clathrus ''Clathrina clathrus'' is a species of calcareous sponge belonging to the family Clathrinidae.
