Owston's Dogfish
Centroscymnus owstonii
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. It reaches a length of 121 cm.
This species is distributed in deep-sea communities throughout the western and eastern Indian Ocean as well as in the south-central Atlantic Ocean and the South Pacific Ocean (Tasmania).

What it does
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).

In human culture
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.
