Biology     Glossary (e.g. epibenthic)

Inhabits bays, harbors, lagoons, and seaward reefs (Ref. 9710). May drift with young at surface among Sargassum (Ref. 9710). Usually solitary or in small groups (Ref. 9710). Feeds on benthic invertebrates like mollusks and crustaceans (Ref. 4727). Oviparous (Ref. 205). Consumed mostly fresh, smoked, and dried salted. The flesh is of excellent quality. Because it is resistant to capture, it proliferates and competes for food with other species (Ref. 5377).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.01532 - 0.02482), b=2.96 (2.89 - 3.03), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.5 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.18-0.43; tm=1).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
Price category (Ref. 80766):   High.
