背的软条 (总数) : 63 - 92; 臀鳍软条: 54 - 79; 脊椎骨: 47 - 49. A deep bodied cusk eel distinguished by the following characters: head 3.0-3.9 times in SL; eye diameter 5.5-6.8 in HL; interorbital 4.8-6.3 in HL; snout 3.8-5.2 in HL; depth 4.3-6.8 in SL; predorsal length 3.3-4.7 in SL, with distance between pelvic origin to anal origin 2.5-4.4 in SL; absence of pseudobranchiae; pyloric caeca 12-13; median basibranchial tooth patches 2; one opercular spine and 3 short blunt spines at the lower angle of preopercle; differs from its congeners in origin of dorsal fin which is above preopercle, no pseudobranchial filaments, pectoral fins and pelvic fins are short and not reaching anus (Ref. 124036)
Body shape (shape guide): elongated; Cross section: compressed.
A benthic species found on the continental slope (Ref. 75154). Uncommon species (Ref. 34024). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
