Short description Identification keys | Morphology | Morphometrics

Dark brown bars on caudal and pectoral fins; bars on pectoral fin irregularly joined (Ref. 26938).

Biology     Glossary (e.g. epibenthic)

Commonly found in seagrass beds and rocky cuts in coastal bays and lagoons, and in shallows along open coast. In western coast of Florida, adults spawn in February and March (Ref. 26938). Nesting males produce grunt calls called the boatwhistle as advertisement of competition among males and to attract females (Ref. 45338). Neither opercular nor dorsal gland is venomous (Ref. 57406).

Estimates based on models

Preferred temperature (Ref. 123201): 23.3 - 27.9, mean 24.6 °C (based on 316 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00798 - 0.02079), b=3.06 (2.92 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.6 se; based on size and trophs of closest relatives
Generation time: 5.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.218; tm=1+).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100).
