Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Adults occur near bottom (Ref. 2850). Young to 7.2 cm are pelagic or bathypelagic, usually associated with jellyfish (Ref. 6885). Juveniles take shelter under the medusae and are often mistaken for medusafish Icichthys lockingtoni (Ref. 50276).

Estimates based on models

Preferred temperature (Ref. 123201): 1.4 - 8.9, mean 4.7 °C (based on 1470 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00680 - 0.04443), b=2.97 (2.75 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.1 se; based on diet studies.
Generation time: 6.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
