Borojevia paracerebrum is a species of calcareous sponge from Mexico. The species is named after its similarity to Borojevia cerebrum .
The single known specimen was found encrusting on a specimen of Euryspongia rosea . It is ramose, with a smooth surface and is 3 to 4 cm in extent and up to 6 mm thick. The tightly woven anastomosing tubes are 100-180 μm in diameter. The approximately circular openings on the surface are 100-200 μm in diameter. Oscula have not been clearly identified. Large triactines and a few large tetractines occur in the choanosome. Approximately a third of the small tetractines have three rows of spines along the distal portion of the apical ray.
The large, regular triactines are equiangular, equiactinal, flat, not, or only slightly, raised (as a tripod), with sharp-pointed rays c. 115 μm long and c. 11.8 μm in diameter at the base. The large parasagittal triactines are like the regular triactines but with one ray up to 20% longer than the other two rays. The large, regular tetractines are similar to the large triactines with the addition of a shorter, smooth apical ray c. 110 μm long and c. 11.5 μm in diameter at the base. The small, regular triactines are equiangular, equiactinal sharp-pointed rays c. 56 μm long and 5.6 μm in diameter at the base. The small, regular tetractines are generally similar to the small triactines with an addition of an apical ray. This ray can be accurately measured in only a few cases where it is only slightly (10%) shorter than the basal rays. The basal rays are c. 58 μm long and c. 5 μm in diameter at the base. About 65% of the small tetractines have three rows of spines along the proximal portion of the distal half of the apical ray. The number of spines in each row ranges from two to five but is typically three or four. Their length often exceeds the diameter of the adjacent portion of the apical ray. The three spine rows are oriented at the same angles as the basal rays. The spines and ray apex appear to have a granular rather than a smooth surface. The small, sagittal tetractines are approximately the same size as the small regular tetractines with paired rays curved towards the unpaired ray. They constitute a small percentage of the tetractines. [1]
The phalanges are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones.
Cetopsis is a genus of catfishes of the family Cetopsidae.
Synodontis granulosus is a species of upside-down catfish endemic to the Democratic Republic of the Congo, Burundi, Zambia, and Tanzania, where it is only known from Lake Tanganyika. It was first described by Belgian-British zoologist George Albert Boulenger in 1900, from specimens collected at multiple points along the shore of Lake Tanganyika. The species name comes from the Latin word "granulum", meaning of grain, and refers to the granular papillae present on the skin of the fish's body.
Anheteromeyenia argyrosperma is a freshwater sponge found across North America.
Arturia africana is a species of calcareous sponge from South Africa.
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 chrysea is a species of calcareous sponge from New Caledonia. The species epithet refers to the light yellow colour of the sponge.
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.
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 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.
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.
Clathrina mutsu is a species of calcareous sponge from Japan. The species is named after the type locality, Mutsu Bay
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.
Arturia tenuipilosa is a species of calcareous sponge from Sri Lanka. The name refers to the very thin, hair-like oxea present in this species.
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.
Brattegardia is a monotypic genus of calcareous sponge with a single species: Brattegardia nanseni from Norway. The genus is named after the Norwegian marine biologist Torleiv Brattegard. The species is named after Norwegian helminthologist Fridtjof Nansen.
