Size / Weight / Age

Max length : 70.0 cm TL male/unsexed; (Ref. 30573); common length : 40.0 cm TL male/unsexed; (Ref. 30573); max. published weight: 4.0 kg (Ref. 43448); max. reported age: 23 years (Ref. 35874)

Length at first maturity
L_m 33.2 range ? - ? cm

Environment

Marine; benthopelagic; depth range 25 - 1300 m (Ref. 9833), usually 400 - 600 m (Ref. 27121)

Climate / Range

Subtropical, preferred 27°C (Ref. 107945); 45°N - 43°S, 180°W - 180°E

Distribution

Circumglobal, excluding the northeast Pacific and Mediterranean Sea (Ref. 9833). Western Atlantic: Gulf of Maine to the Gulf of Mexico (Ref. 6743). 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).

Short description

Dorsal spines (total): 4; Dorsal soft rays (total): 13-16; Anal spines: 4; Anal soft rays: 26 - 30. First infraorbital bone with a spine projecting laterally on anterior end. Lateral line extends to caudal fin. A fleshy disk on inner face of exposed area of scale. In young fishes, the 2nd dorsal ray is elongate (Ref. 559). Ref. 27363 notes pectoral fins with one spine and 17 soft rays (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). Juveniles pelagic (Ref. 9072). Feed mainly on fish, crustaceans and cephalopods (Ref. 33648). Oviparous, spawn in batches (Ref. 30291). Eggs and larvae are pelagic (Ref. 30291). Marketed frozen and eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
