背的軟條 (總數): 63-92; 臀鰭軟條: 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)
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).
