> Beryciformes (Sawbellies) > Berycidae (Alfonsinos)
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).
