توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل): 2; خارهاي باله مخرجي 0. This species is distinguished by the following characters: snout long. Slender, and sharply pointed, its length 43-48% HL, 0.5-0.7 into orbit diameter; normally no scales on ventral aspects of head except along anterolateral margin of snout; naked areas dorsally behind anterolateral margins of snout confined to narrow strips; anterolateral edges of snout not supported by bone (median and lateral processes of nasal bone not united); ventral light organ very small, short, situated just before anus; scales large, fairly deciduous, spinules short, imbricate, aligned in 8 to 10, slightly divergent rows; overall color is gray-brown, with a bluish band around trunk; the underside of the head dusky to densely punctuated; the orbit rim black; the fins blackish to dusky (Ref. 1371, 36027).
Feeds on deep-sea decapod crustaceans, gastropods, and polychaetes (Ref. 1371). Probably taken occasionally in by-catch of commercially important fishes (Ref. 1371).
