  • Ovoviviparous (ref: fishbase)
  • Neonates near surface waters (ref: Wiki)


  • Fishbase reports: Deep-water, preferred 16C, but this seems a high temperature for deep water
  • Yearly spawning assumed
  • Offset of 1.5 yr has been applied to age-at-length since growth after 1 yr is incompatible with before 1 yr. Age was estimated from otolith readings
