Morphologie | Morphométrie
Épines dorsales (Total): 7 - 9; Rayons mous dorsaux (Total): 31-34; Épines anales 0; Rayons mous anaux: 32 - 36. No swim bladder (Ref. 128162),
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. There are indications that the females perish after spawning. The larvae stay dispersed between the surface and 500 m; they do not undergo daily migrations (Ref. 2058).
