📖 Overview

Found in deep waters from 80-370 m on slopes of islands, sea mounts or continental shelves. Feeds on benthic fishes and large invertebrates . Considered rare in Tahiti but quite common in atolls . The species is easily confused with E. poecilonotus, E. radiatus, or E. tuamotuensis, three closely related deep-water groupers. Known to be ciguatoxic at Mauritius. Uncommon in local markets (probably due to it deep-water habitat).
