Abe, 1966 }} The bareskin dogfish (Centroscyllium kamoharai) is a little-known, deepwater dogfish shark of the family Etmopteridae.[1][2] This species is found in the western Pacific from southern Japan to western and southeastern Australia as well as in New Zealand waters.[3] 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 denticles, and is dark in color with white-tipped fins. It is stout and grows to a maximum of 40 cm.[4][5] 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 others bioluminescent sharks.[6] Conservation statusThe New Zealand Department of Conservation has classified the bareskin dogfish as "Data Deficient" under the New Zealand Threat Classification System.[7] References{{Portal|Sharks}}1. ^Finucci, B. & Kyne, P.M. 2018.
