Discussion
- Males are not assumed to differ from females; VediOrlo2016 give tp=18yr at Lp=55cm for females and tp=14yr at Lp=66cm for males, while the scanty data do not support enough growth differences between sexes; Lm=122cm(unsexed) is 20 cm more than their max observed length
- temperatures are guessed, based on deep water occurence
Facts
- Leptocephalus larva lives in surface waters and can become larger than the adult, which lives 120 till 4900 m deep (Ref: Wiki)
- feeds on sea anemones, molluscs and echinoderms (Ref: Wiki)
- Duration of the leptocephalus-stage is unkown, 3 yrs in related species (Ref: VediOrlo2016)
