Biology     Glossary (e.g. 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00243 - 0.01426), b=3.07 (2.85 - 3.29), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.5 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (tm= 5.1; K= 0.18).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100) .
Price category (Ref. 80766):   Unknown.
