Biology     Glossary (e.g. epibenthic)

Found in sheltered bays. Color varies from either white, orange or yellow with light patches and sometimes network of fine dark lines; also with narrow lines across snout.

Estimates based on models

Preferred temperature (Ref. 123201): 26.1 - 28.6, mean 27.5 °C (based on 248 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
