Ökologie
seewasser bathypelagisch; tiefenbereich 10 - 2000 m (Ref. 27000), usually 200 - 900 m (Ref. 33390). Deep-water; 67°N - 40°S, 180°W - 180°E

Länge bei der ersten Reifung / Größe / Gewicht / Alter
Geschlechtsreife: Lm ?, range 2 - ? cm
Max length : 4.6 cm SL Männchen/unbestimmt; (Ref. 128822); max. veröff. Alter: 1.00 Jahre (Ref. 5162)
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 13 - 15; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 18 - 20.
Body shape (shape guide): elongated.
Oceanic, precise depth range dependent upon developmental stage, latitude, season (Ref. 4769). Generally horizontally oriented (Ref. 4769). Feeds on small zooplankton, mostly copepods (Ref. 5162). Sexually dimorphic with large females and small males (Ref. 9503). Sex ratio vary with size groups but is about 1:1 around spawning. Length-frequency histograms are bimodal; has a two-year life cycle (Ref. 82363).
