Größe / Gewicht / Alter
Geschlechtsreife: Lm ? range ? - ? cm
Max length : 24.7 cm SL Männchen/unbestimmt; (Ref. 9791)
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 29 - 37; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 26 - 34; Wirbelzahl: 47 - 53.
Body shape (shape guide): elongated.
Normal diurnal distribution is between 700 and 1200 m The shallowest diurnal capture (500-600 m) is of one of the smallest specimens (4.3 cm) and the deepest (1500-1600 m) is of one of the largest (20.4 cm), indicating a trend for the diurnal depth to increase with increasing size (Ref. 9791). Nocturnal distribution is between 110-700 m (Ref. 9791). Feeds on decapods and euphausiids (Ref. 6715). Minimum depth from Ref. 58018.
