Biology     Glossary (e.g. epibenthic)

Adults occur in shallow, clear, warm, coastal waters over coral reefs. Often near the shelter of elkhorn corals and gorgonians (Ref. 9710). Juveniles are encountered over sand bottoms with or without seagrass (Thalassia), and over muddy bottoms of lagoons or mangrove areas. Young sometimes enter brackish waters. Sometimes form resting aggregations during the day. Feed on fishes, shrimps, crabs, worms, gastropods and cephalopods. Considered a good food fish, it is marketed fresh or frozen (Ref. 55). Maximum length for female taken from Ref. 3093.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00996 - 0.02640), b=3.00 (2.86 - 3.14), based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.7 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (35 of 100) .
Price category (Ref. 80766):   High.
