Biologi     Ordlista (t.ex. epibenthic)

Adults prefer to inhabit caves and shipwrecks (Ref. 27121). Juveniles congregate below floating objects (Ref. 27121). Usually solitary. Feed on large crustaceans, cephalopods and benthic fishes (Ref. 27121). Spawn in the summer (Ref. 35388). Are primary gonochorists (Ref. 58421). Marketed fresh or frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Minimum depth reported from Ref. 6633.
