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.
Formed of regularly and tightly anastomosed, very thin, delicate tubes. In shape it is lobose, and full of folds. Each fold is flat, thin and delicate. Oscula have not been observed. In the centre of each fold there is a large tube (pseudoatrium), with choanocytes, surrounded by thinner tubes. Covering the external tubes, there are some large triactines. The wall of the tubes is very thin. The tubes are perpendicular to the surface, and converge at a large central tube. Above the central tube, it is possible to see some lacunes. The skeleton is formed of two types of triactines, of different sizes, and tetractines of the same size as the shorter triactines. The spicules are equiradiate and equiangular. Actines are conical with sharp tips. The large triactines are present only in the outside of the external tubes, where they lie side by side. The other triactines are spread along the tubes. Tetractines are less abundant than triactines. Their apical actine is almost the same thickness as the other actines. It is conical, sharp, shorter, straight and smooth and projected inside the tubes. [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.
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 ceylonensis is a species of calcareous sponge from Sri Lanka. The species name is derived from Ceylon, the former name of Sri Lanka.
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 name is derived from Dendy's uncertainty about the validity of the species, believing his specimens could, in fact, represent juvenile Leucosolenia cavata.
Clathrina helveola is a species of calcareous sponge from Australia. The species name means "pale yellow" in Latin and refers to the species' colouration.
Arturia hirsuta is a species of calcareous sponge from South Africa. The name refers to the hispid surface of the sponge.
Clathrina jorunnae is a species of calcareous sponge from Norway. The species is named after Jorunn Berg, Hans 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.
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.
Ernstia minoricensis is a species of calcareous sponge in the family Clathrinidae found in Spain. The species is named after the island of Menorca where the type specimen was discovered.
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.
