Gephyroberyx japonicus, the big roughy or blueberry roughy, is a species of fish in the family Trachichthyidae.[2] It is endemic to the northwest Pacific off Japan, Taiwan and Hawaii,[2][3][4] and can be found at depths between 300 and 1,500 m (980–4,920 ft).[5] It can reach 30–35 cm (12–14 in) in length.[6] Based on broadly overlapping morphological features it is sometimes (e.g., by IUCN) considered a synonym of G. darwinii.[1][4][7]

It is sometimes seen in deep-sea exhibits in public aquariums and it has spawned in captivity.[6]
