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.

Worldwide in temperate and tropical latitudes, except the eastern Pacific. Eastern Atlantic: Greenland, Iceland, and Norway to Western Sahara and South Africa, including western Mediterranean. Western Atlantic: south to Brazil. Also found in Argentine (Ref. 2806). Indo-Pacific: East Africa (including the Madascar Ridge and Saya de Malha Bank, Ref. 33390) to Japan, 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).
除了東太平洋以外,遍及全球的溫帶與熱帶的緯度。 東大西洋: 格陵蘭，冰島與挪威到西撒哈拉與南非, 包括地中海西部。 西大西洋: 南至巴西。 印度-太平洋: 東非 (包括 Madascar 脊與 Saya de Malha 岸堤, 參考文獻 33390) 至日本，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)
