Etymology: Beryx:Greek, beryx or berys = a name of a fish. Cuvier & Valenciennes (1829:221) precise that the name was used by Gesner from Varinus, but with no indication whatsoever helping identifying any species. After D'Arcy Wentworth Thompson (A glossary of Greek fishes, 1947), the name actually seems to come originally from Hesychius, but perhaps the name was not originally a fish name. Thompson compares it to meryx (ruminant), applied on skaros (Scarus), so it may have been applied on a parrot fish referring to its browsing/grazing behavior described by Aristoteles and followers.

Eastern Atlantic: off southwestern Europe and the Canary Islands (Ref. 7413) to South Africa (Ref. 4179). Indo-Pacific: East Africa (including Saya de Malha Bank, Ref. 33390) to Japan, Hawaii, Australia, and New Zealand (Ref. 5755). The limited number of records in the western Pacific is doubtless the result of limited fishing effort below 200 m (Ref. 9833). Eastern Pacific: Chile (Ref. 27363).

Adults inhabit the outer shelf (180 m) and slope to at least 1,300 m depth, probably moving further from the bottom at night; often found over seamounts (Ref. 9833) and underwater ridges (Ref. 33648). Are considered as one of the straddling stocks in the northwest Pacific (Ref. 87829). They feed mainly on fish, crustaceans and cephalopods (Ref. 33648). Oviparous, spawn in batches (Ref. 30291). Juveniles (Ref. 9072), eggs and larvae are pelagic (Ref. 30291). Marketed frozen and eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
Spawning occurs about 10 to 12 times at intervals of about 4 days during the breeding season (Ref. 58433).Circumglobal ，除了東北太平洋與地中海.(參考文獻 9833) 西大西洋: 緬因灣到墨西哥灣.(參考文獻 6743) 東大西洋: 外海的歐洲西南方與加納利群島 (參考文獻 7413) 到南非.(參考文獻 4179) 印度-太平洋: 東非 (包括 Saya de Malha 岸堤, 參考文獻 33390) 至日本，夏威夷，澳洲與紐西蘭.(參考文獻 5755) 在西太平洋的有限的數目紀錄在 200 公尺之下無疑地是限制魚撈的結果。 (參考文獻 9833) 東太平洋: 智利.(參考文獻 27363)
