Taggstrålar i ryggfenan (totalt) : 7 - 9; Mjukstrålar i ryggfenan (totalt) : 31 - 34; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 32 - 36. No swim bladder (Ref. 128162),
Body shape (shape guide): elongated.
Found beyond 1,000 m depth. Both males and females often occur on the surface. In January and February, this fish is often found at a depth range of 300-500 m, in March and April, it is found between 100-120 m. Reproduction takes place in February until March.
