Roughskin dogfish

The New Zealand Department of Conservation has classified the roughskin dogfish as "Not Threatened" under the New Zealand Threat Classification System. == Ecosystem ==

Centroscymnus owstonii holds importance in its ecosystem as a predator and component of the upper slope assemblage, as it maintains an ecological balance in deep-sea communities. Particularly, in the depth range of 750–2050 meters, it contributes substantially (>60%) to the biomass and assemblage similarity. Diet As a top predator, the prey of C. owstonii consists mainly of fishes, with small proportions of crustaceans, squid and salps. The fish prey were predominantly hoki, with some mesopelagic sea bream (B. australis and B. brama), slender tuna (Allothunnus fallai), and a demersal rattail (Coelorinchus bollonsi). ==Etymology==

The fish is named in honor of Alan Owston (1853‒ 1915), an English businessman, a yachtsman, and a collector of Asian wildlife, who obtained the holotype. ==References==
