Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 78 - 82; Anal spines: 0; Anal soft rays: 61 - 65; Vertebrae: 38. Two dark spots along gill opening below pectoral fin. Dark blotch a beginning of straight part of lateral line (Ref. 559). Soft ray count of pectoral fin refers to that on ocular side.

Biology     Glossary (e.g. epibenthic)

Inhabits muddy and sandy bottoms of the continental shelf (Ref. 9774). Feeds mainly on small demersal fishes (Ref. 9774). Marketed fresh (Ref. 9774).

Estimates based on models

Preferred temperature (Ref. 123201): 23.9 - 28.6, mean 28 °C (based on 95 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00443 - 0.01132), b=3.14 (3.01 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.73 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
Price category (Ref. 80766):   Very high.
