The blue-eye trevalla is a large deep-water fish of the medusafish family (Centrolophidae) from the cool waters of the southern hemisphere. The species grows to about 140 cm and has a robust, dark body with conspicuously large eyes. Adults live mostly over or near rocky bottoms at 100-300 metres; by day they stay close to the bottom and at night rise in the water column, following concentrations of food. The fish feeds on salps, squid and fishes. Juveniles often shelter under drifting weed. The blue-eye trevalla is an important commercial fish and is harmless to humans.
