> 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..

Environment: milieu / climate zone / depth range / distribution range Ecologia

marino batidemersale; distribuzione batimetrica 110 - 1300 m (Ref. 126224), usually 200 - 800 m (Ref. 126224). Deep-water; 70°N - 48°S, 180°W - 180°E

Distribuzione Stati | Aree FAO | Ecosystems | Presenze | Point map | Introduzioni | Faunafri

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).

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 4; Raggi dorsali molli (totale) : 18 - 20; Spine anali: 4; Raggi anali molli: 25 - 30. Body deep, compressed and has a large eye. Top of head, iris, back and all fins bright blood red. Orbital bones, cheeks and opercular bones shiny white. Breast shiny yellowish white. Body silvery with thin lengthwise lines (Ref. 37108).

Biologia     Glossario (es. epibenthic)

Found in ca. 500 m on mud or sandy mud bottom (Ref. 11230). Occurs on the continental slope; adults demersal, young pelagic (Ref. 9563). Feeds on crustaceans, small fishes and cephalopods (Ref. 3321). A 35 cm SL specimen was found in the stomach of Latimeria (Ref. 58472). Young have heavy spines on the head (Ref. 35388).
