Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 79 - 94; Anal spines: 0; Anal soft rays: 63 - 75. In males, the 1st and 2nd rays of the pectoral fin become filamentous (Ref. 35237).

Biology     Glossary (e.g. epibenthic)

Predator which lives on the bottom where it hides partially or almost completely in the sand in order to disguise itself in the environment. Feeds on small fish and invertebrates. Exhibits sexual dimorphism (Ref. 35237). Marketed fresh (Ref. 5217).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous (Ref. 101737). Distinct pairing (Ref. 205). Females produce numerous eggs in multiple spawnings during a prolonged spawning period (Ref. 101737).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00776 (0.00608 - 0.00991), b=3.08 (3.03 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level
(Ref. 69278) 		3.6   ±0.0 se; based on diet studies.
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (23 of 100). 🛈
