Centroscyllium Ornatum
''Centroscyllium'' is a genus of big-eyed, deepwater Squaliformes, dogfishes with no anal fin, a grey or black-brown body, and dorsal spines, with the second one being much larger than the first. Seven extant species are described. Species * ''Centroscyllium excelsum'' Shirai Shigeru, Shirai & Kazuhiro Nakaya, Nakaya, 1990 (highfin dogfish) * ''Centroscyllium fabricii'' Johan Reinhardt, J. C.

Black Dogfish
The black dogfish (''Centroscyllium fabricii'') is a species of Squaliformes, dogfish shark in the family (biology), family Etmopteridae. It is common over the outer continental shelf and continental slope at depths of . Females generally inhabit deeper water than males, and depending on the region, smaller sharks may occur at different depths than larger ones. This species is distributed widely in the Atlantic Ocean, from Greenland and Iceland to Virginia and West Africa in the north, and off southwestern Africa and Argentina in the south. The largest member of its family, the black dogfish, typically measures long. It has a stocky, dark brown body that is darker below than above, and bears scattered, minute bioluminescence, bioluminescent organs. Its two dorsal fins are preceded by stout spines, and the anal fin is absent. Active and shoaling and schooling, schooling, the black dogfish is an opportunistic predator and scavenger that mainly consumes bony fishes, crustaceans, and ...

Centroscyllium Kamoharai
The bareskin dogfish (''Centroscyllium kamoharai'') is a little-known, deepwater Squaliformes, dogfish shark of the family (biology), family Etmopteridae. This species is found in the western Pacific from southern Japan to western and southeastern Australia as well as in New Zealand waters. The bareskin dogfish has no anal fin. It has grooved dorsal spines with the second larger than the first, a smaller first dorsal fin, blunt nose, large eyes, large nostrils, widely spaced and sparse Dermal denticle, denticles, and is dark in color with white-tipped fins. It is stout and grows to a maximum of 40 cm.FAO Species Catalogue Volume 4 Parts 1, Sharks of the World Like other species in the family Etmopteridae (lanternsharks), the bareskin dogfish has a bioluminescent organ on the ventral side; however, perhaps owing to the depth at which the species lives, it has relatively fewer photophores on its ventral skin than other bioluminescent sharks.
