Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 2; Εδρικές άκανθες: 0. Black or blackish brown in color, dorsal fins with very small fin spines, very long snout, greatly elongated labial furrows that nearly encircle mouth, lanceolate upper teeth and bladelike lower teeth with moderately long, oblique cusps, fairly slender body that does not taper abruptly from pectoral region, moderately large lateral trunk denticles with partly smooth, oval, cuspidate crowns in adults and subadults (Ref. 247).

A fairly common species found on continental and insular slopes (Ref. 6871), on or near the bottom (Ref. 5578). Feeds mainly on fish and cephalopods (Ref. 6871). Ovoviviparous (Ref. 205), with 4-8 young in a litter (Ref. 6871), born at 28-35 cm (Ref. 26346). The flesh is high in mercury; utilized as fishmeal and source of squalene (Ref. 6871).
