Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 0; Espinhos anais: 0; Raios anais moles: 14 - 17; Vértebras: 78 - 80. Dark brownish, silvery ventrally; paired fins and caudal fin uniformly black. Body extremely elongate. Large adults with a pair of dermal keels midlaterally on each side. Small, flexible projection at tip of lower jaw. Gill membranes joined forward, below anterior edge of eye, and free from isthmus. No rayed dorsal fin. No scales (Ref. 43939). In adults, head depth 29-33% of lower jaw length. Postorbital area 8.1-9.7% SL or 34.4-38.8% (less than 3 times smaller than HL). Rear edge of gill cover overlaps with the vertical of the 5th vertebrae. Postadipose distance 7-8% SL (Ref. 31260).

Biologia     Glossário (ex. epibenthic)

Found in a wide range of depths, sometimes near surface (Ref. 2850) to below 2,000 m. Larger adults inhabit colder water toward the poles, whereas, the young and smaller adults inhabit more temperate regions (Ref. 35956). Feed on mollusks, crustaceans, marine worms, coelenterates, salps, and fishes (Ref. 4525, 6885). Its distensible body wall and large stomach can accommodate prey up to half of its own length. Oviparous, with planktonic larvae (Ref. 35956). Preyed upon by albacore, Pacific lancetfish, halibut, steelhead salmon, blue shark, pomfret, and whales (Ref. 6885).
