Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 16 - 17; Anal spines: 3; Anal soft rays: 8. Have a large spots on the soft-rayed portions of the fins and a fine pattern of small close-set spots on the body and spinous portions of the fins (Ref. 37816); further characterized by having ctenoid scales on body except cycloid anteriorly above lateral line, thorax and abdomen; body with auxiliary scales; greatest depth of body 2.8-3.2 in SL; rounded caudal fin; pelvic fins, 1.7-2.1 in head length (Ref. 90102); head length 2.4-2.6 times in SL; convex interorbital, slightly concave dorsal head profile at eyes; subangular preopercle, shallow notch just above the angle and the serrae at the angle enlarged in juveniles; straight upper edge of operculum; diameter of posterior nostrils about twice that of anterior nostril; maxilla reaches vertical at rear edge of eye; 2-4 rows of teeth on midlateral part of lower jaw; pyloric caeca 30 (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Found in a variety of habitats. Solitary (Ref 90102). Juveniles (8-21 cm SL) have been taken from mud bottoms, seagrass beds, mangrove swamps, and from coral reefs in depths of 1 to 16 m; adults in coral reefs at depths of 18 to 180 m (Ref. 89707). Stomach contents reported to include juvenile clappid crab, a stomatopod, and a gastropod (Ref. 6448).

Estimates based on models

Preferred temperature (Ref. 123201): 21.8 - 28.2, mean 26.2 °C (based on 240 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00568 - 0.02430), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.62 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100).
Price category (Ref. 80766):   Very high.
