簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 2; 背的軟條 (總數): 122; 臀棘 0; 臀鰭軟條: 94. Head large, scaled completely except for a narrow ventrolateral strip on snout; eyes also large; snout short, pointed and with tubercular scales along its leading edge; chin with a small chin barbel. Body tapering to a point posteriorly from behind the insertion of the first dorsal-fin spine. Scales adherent, with 3 to 5 divergent rows of coarse spinules. Pyloric caeca 12 to 14. Overall color is gray to grayish-brown in young, turning to dark brown in adults; fins generally dark. Branchiostegal rays: 6-6 (Ref. 36385).
A benthopelagic mid-slope species, that appears to wander off slope bottoms into midwater (Ref. 1371). Adults feed on small fish, euphausiids, prawns, amphipods and cephalopods (Ref. 1371). Oviparous, with planktonic larvae (Ref. 36385).
