توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل): 16-17; شعاع نرم باله مخرجي: 18 - 20. This species is distinguished by the following characters: elongated body tapering toward caudal fin; snout 1.25 times shorter than eye; morphometric values (IOM specimen only), in % of SL: head length 15.7; snout length 2.4; eye diameter 3.0; least interorbital width 4.0; barbel length 10.8; upper jaw length 13.3; postorbital organ length 3.0; ditto, greatest depth 0.9, entire black surrounding area 4.2; predorsal, preanal and prepelvic distances 78.3, 78.3 and 66.3, respectively; dorsal- and anal-fin base length 12.7 and 13.9, respectively; pelvic-fin length 12.1; greatest body depth 12.1; least depth of caudal peduncle 2.4; the opercle almost straight dorsally, with posteroventral corner somewhat extended, rounded; gill filaments extending slightly beyond gill cover; gill filaments shortened in upper half of ceratobranchial of first arch (twice shorter than lowermost filaments of ceratobranchial-1). Color of skin turns to rusty brown after more than 40 years of storage (Ref. 120405).
Mesopelagic species (Ref. 75154).
