Biology     Glossary (e.g. epibenthic)

Adults occur mainly over rocky and muddy bottoms. Uncommon around coral reefs. Usually rest on the bottom (Ref. 9710). Juveniles may be found in shallow water, but adults are usually taken from depths of 70-330 m (Ref. 13442). Feed on a wide variety of fishes and invertebrates. Are protogynous hermaphrodites (Ref. 55367). Most females transform to males between ages 7 to 14. Susceptible to red tide toxin (Ptychodiscus brevi) (Ref. 5222). Marketed fresh or frozen. The world record for hook and line, 39 lbs., from Cape Canaveral, Florida (Ref. 13442).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00936 - 0.02133), b=3.01 (2.89 - 3.13), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.1-0.18; tm=4-6; tmax=25; Fec=1.4 million).
Vulnerability (Ref. 59153):  High vulnerability (63 of 100) .
