Clathrina ceylonensis is a species of calcareous sponge from Sri Lanka. [1] The species name is derived from Ceylon, the former name of Sri Lanka.
Cormus massive, formed of thin, irregular and tightly anastomosed tubes, with a reticulated surface. According to the original description, water-collecting tubes were present. The skeleton has no special organisation, comprising equiangular and equiradiate triactines. Actines are conical, with blunt tips, never rounded. Dendy described this species as a variety of Clathrina coriacea . He noted the presence of water-collecting tubes as ‘small but prominent true oscula formed each by the coalescence of several tubes in a projection from the general surface’. He also found triactines measuring about 88 mm/8 mm, and ‘few very slender oxea’, which were probably trichoxeas. Klautau and Valentine studied the holotype. No trichoxeas were found, but these spicules are sometimes difficult to find. Klautau and Valentine therefore decided not to consider the presence of trichoxeas in their description. Klautau and Valentine elevated this variety to the status of a species because C. ceylonensis is very distinct from C. coriacea. Despite morphological similarities, such as the presence of water-collecting tubes and the size of the triactines, they can easily be distinguished. C. coriacea has undulated actines with a constriction near the tip, which is rounded or blunt, while C. ceylonensis has straight actines with blunt, unrounded tips. The distribution of C. coriacea seems to be restricted to northern Europe, while C. ceylonensis occurs only in the Indian Ocean. [2]
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".
Arturia africana is a species of calcareous sponge from South Africa.
Clathrina angraensis is a species of calcareous sponge from Brazil. The species epithet refers to Angra dos Reis, the Portuguese name for the Botinas Islands.
Borojevia aspina is a species of calcareous sponge from Brazil. The species name refers to the lack of spines in the apical actine.
Clathrina aurea is a species of calcareous sponge from Brazil. Specimens of this species were previously misidentified with Clathrina clathrus
Borojevia brasiliensis is a species of calcareous sponge from Brazil, from which the species' name is derived.
Borojevia cerebrum is a species of calcareous sponge from the Mediterranean Sea. The species name refers to the brain-like appearance of the sponge.
Clathrina chrysea is a species of calcareous sponge from New Caledonia. The species epithet refers to the light yellow colour of the sponge.
Clathrina conifera is a species of calcareous sponge from Brazil. The species name refers to the cone-shaped appearance of the triactines.
Clathrina cylindractina is a species of calcareous sponge from Brazil. The species is named after the cylindrical-shaped actines the sponge possesses.
Arturia dubia is a species of calcareous sponge in the genus Arturia from Australia. The species was first described as Leucosolenia dubia by Arthur Dendy in 1891. The name is derived from Dendy's uncertainty about the validity of the species, believing his specimens could, in fact, represent juvenile Leucosolenia cavata.
Arturia hirsuta is a species of calcareous sponge from South Africa. The name refers to the hispid surface of the sponge.
Clathrina hispanica is a species of calcareous sponge from Spain. The species is named after the country of Spain, where it was discovered.
Clathrina hondurensis is a species of calcareous sponge from Belize. The species is named for British Honduras, the former name of Belize, at the time the holotype was collected in 1935.
Clathrina jorunnae is a species of calcareous sponge from Norway. It is only known from Trondheimsfjord, its type locality, where it was dredged from depths of 25–250 m (82–820 ft). The specimen was attached to a bryozoan of the genus Reteporella. The species is named after Jorunn Berg, Hans Tore Rapp's grandmother, who introduced Rapp to marine animals.
Clathrina laminoclathrata is a species of calcareous sponge from Australia. The species name is in reference to its unusual lamina.
Arturia sueziana is a species of calcareous sponge from Egypt. The species is named after the Egyptian city of Suez where the holotype was discovered.
Borojevia tetrapodifera is a species of calcareous sponge from New Zealand. The species is named after the presence of tetrapods, the only Clathrinid sponge known to possess such spicules.
Clathrina antofagastensis is a species of calcareous sponge from Chile. The species is named after Antofagasta, Chile, where the holotype was discovered.
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.
