Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 90.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 4448)
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 11 - 13. Body greyish-black to bluish black in color; top of head, gill isthmus and branchiostegal membranes black (Ref. 3974). Deeply pigmented sheath of lateral line. Absence of scales on the top of the head and presence of scales on the opercular bone (Ref. 37108).
Found on the lower slope, continental rise and upper abyss, primarily between 4° and 2°C isotherms. Feeds on polychaetes, crustaceans, echinoderms and echiurids. Hovers above or rests on bottom. Long slender pectorals are commonly held erect pointing upward and forward, these may serve a sensory function (Ref. 6727).
