Teleostei (teleosts) > Zeiformes (Dories) > Zeidae (Dories)
Eponymy: Derived from zaeus, an ancient Greek name for this fish dating back to Pliny’s Natural History. [...] There are many alternative names for this fish and almost as many theories as to the origin of the name. [...] (Ref. 128868), visit book page.

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

Marine; brackish; benthopelagic; oceanodromous (Ref. 35388); depth range 5 - 400 m (Ref. 9563), usually 50 - 150 m (Ref. 4968). Temperate; 75°N - 49°S, 17°W - 177°E (Ref. 54935)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9 - 11; Dorsal soft rays (total): 22 - 24; Anal spines: 4; Anal soft rays: 20 - 23. Gill rakers rudimentary. Minute scales present. Highly compressed body (Ref. 4253). Large dark spot, surrounded by a light ring on each side of the body (Ref. 35388).

Biology     Glossary (e.g. epibenthic)

Found in areas close to the sea bed (Ref. 6390). Generally solitary. Feeds mainly on schooling bony fishes, occasionally on cephalopods and crustaceans (Ref. 27121). Reproduction takes place at the end of winter and at the start of spring in the northeastern Atlantic, earlier in the Mediterranean. Eggs are pelagic, maturity reached at 4 years (Ref. 36731). Sold fresh (Ref. 9563) and frozen (Ref. 9988). Can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). The flesh is excellent but is utilized little in West Africa (Ref. 5377).
