Trophic Strategy

provided by Fishbase
A deep-slope upper continental rise species, common in deep waters of most oceans (Ref. 1371). Bathypelagic (Ref. 58426). Feeds on a variety of benthic invertebrates (especially crustaceans and holothuroids) when young, switching to primarily mesopelagic and bathypelagic fish, and sea urchins and cephalopods as adults (Ref. 1371). Feeds on fish, squids, crustaceans and echinoderms (Ref. 1371). Smaller fish feeds entirely on benthic animals, as it grows, it feeds on pelagic fishes and cephalopods (Ref. 51907).
