The roughskin dogfish (Centroscymnus owstonii) is a sleeper shark of the family Somniosidae, found around the world on continental shelves in tropical, subtropical and temperate seas, at depths of between 100 and 1,500 m. [2] [3] It reaches a length of 121 cm. [2]
This species is distributed in deep-sea communities throughout the western and eastern Indian Ocean [4] as well as in the south-central Atlantic Ocean and the South Pacific Ocean ( Tasmania). [5]
Conservation status
The New Zealand Department of Conservation has classified the roughskin dogfish as "Not Threatened" under the New Zealand Threat Classification System. [6]
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. [7]
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). [8]
