Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 67 - 70; Anal spines: 0; Anal soft rays: 50 - 53. Color of preserved specimens tan to dark grey on the ocular side; tan or whitish on the blind side. Pectoral fin rays 11-13 on ocular side; 11-12 on blind side. Pelvic fin of ocular side with black spot and shorter than that on the blind side. Gill rakers elongate and pointed. 1st interhemal spine stout.
Inhabits mud and sand bottoms (Ref. 9774). Feeds on crustaceans and other benthic invertebrates (Ref. 9774).

Estimates based on models
Preferred temperature (Ref. 123201): 11.7 - 20.8, mean 15 °C (based on 37 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.17 (3.00 - 3.34), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.5 ±0.44 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 vulnerability (17 of 100).
