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 ''Clathrina antofagastensis'' is a species of calcareous sponge from Chile.

Clathrina Coriacea (Montagu, 1818) Sur Spirastrella Cunctatrix Schmidt, 1868
''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 wit ...

Clathrina Blanca
''Clathrina blanca'' is a species of Calcareous sponge in the genus Clathrina. It was discovered in 1867 and published in 1868 by Nicholas Miklouho-Maclay, on an expedition to the Canary Islands with Ernst Haeckel. Miklouho-Maclay classified it as ''Guancha blanca''; the species name refers to its "lustrous white color", and the Guanches The Guanche were the Indigenous peoples, indigenous inhabitants of the Spain, Spanish Canary Islands, located in the Atlantic Ocean some to the west of modern Morocco and the North African coast. The islanders spoke the Guanche language, which i ... were indigenous people of the Canaries. Haeckel soon after recategorized it into seven different genera, including ''Ascetta blanca''. Multiple rediscoveries in different locations with different names followed, including ''Ascetta macleayi'' from Australia (Von Lendenfeld 1885), and ''Leucosolenia stipitata'' from Victoria (Dendy 1891). It has also been observed in California, and since 1937 it ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 sponge spicule, 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.

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 Clara
''Clathrina clara'' is a species of calcareous sponge 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 triactines are found within the cormus.
