  • bathypelagic; depth range 395 - 1700 m; feeds primarily on pelagic copepods, but also takes mysids, shrimps, cephalopods, fish, polychaetes and gastropods (ref: fishbase)
  • Weight length: W = 0.00129*L^3.232 (ref: fishbase)


  • max age seems very short
  • conversion of pre-anal PL to total length TL of tL data is based on photo: TL = 2.32 * PL
