Borojevia cerebrum is a species of calcareous sponge from the Mediterranean Sea. The species name refers to the brain-like appearance of the sponge.
As the cormus of the holotype is fragmented, it was not possible to determine its organization, or establish the presence of water-collecting tubes. In some parts, the tubes have even collapsed, and it is impossible to distinguish them. The wall of the tubes is thin, comprising an irregular meshwork of triactines, tetractines and a few tripods, which are located only on external tubes. Projecting into the interior of the tubes are the apical actines of the tetractines. Spicules are equiangular and equiradiate triactines, tetractines, and tripods. Triactines are the most abundant spicules. The size of the triactines and tetractines is uniform. The actines of the triactines are conical or cylindrical, while the tetractines are always conical. They are straight, with a blunt tip. The apical actine of the tetractines is conical, sharp, straight and thinner and shorter than the facial ones. In the distal part, before the tip of the actine, there are sharp spines arranged in 3-4 rows. These spines are directed toward the tip of the actine. Some apical actines, particularly those of young spicules, have only vestigial spines. Tripods are not abundant, as they are located only on the surface of external tubes. They are approximately the same length as the other spicules, but their actines are much more conical and stout. The centre of these spicules is frequently raised, and their tips are sharp. When the centre is not raised, they are similar to large triactines, but it is still possible to recognize them by the shape of the stout conical actines. [1]
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.
Borojevia brasiliensis is a species of calcareous sponge from Brazil, from which the species' name is derived.
Clathrina chrysea is a species of calcareous sponge from New Caledonia. The species epithet refers to the light yellow colour of the sponge.
Clathrina clara is a species of calcareous sponge from India. The name refers to the clear, bright surface of the sponge.
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.
Ascaltis gardineri is a species of calcareous sponge in the family Leucascidae from India and the Seychelles. The species is named after the British zoologist John Stanley Gardiner.
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 laminoclathrata is a species of calcareous sponge from Australia. The species name is in reference to its unusual lamina.
Clathrina lacunosa is a species of calcareous sponge from the British Isles. The species name means "having holes" and refers to the perforations found in the sides of the sponge. It is usually found on vertical solid surfaces at depths down to 220 m. It is distributed in the north-eastern Atlantic from the Arctic to the Mediterranean. It is a fairly common sponge but is often overlooked due to its small size.
Clathrina luteoculcitella is a species of calcareous sponge from Australia. The species name means "yellow pillow" and refers to the appearance of the cormus.
Borojevia paracerebrum is a species of calcareous sponge from Mexico. The species is named after its similarity to Borojevia cerebrum.
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.
Borojevia is a genus of calcareous sponge in the family Clathrinidae. The genus is named after sponge researcher Radovan Borojevic.
