Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 4; Dorsal soft rays (total): 9; Anal soft rays: 8. Ground coloration dark brown, ventral parts of body light brown or white. Back with some darker saddles, sides of body with a row of black blotches. First dorsal fin with an ocellate black blotch on third membrane. Anal fin with a broad distal black streak. Second dorsal fin, caudal fin, pectoral and pelvic fins with brownish spots and blotches (Ref 42832).

Inhabits shallow to deep waters (Ref. 559), on sandy mud bottoms (Ref. 11230). Rarely seen by divers but more commonly encountered in shallow waters (Ref. 90102). Feeds mainly on amphipods, polychaetes, bivalves, gastropods and ophiuroids (Ref. 13374). Minimum depth of 5 m reported from Ref. 90102.

Estimates based on models

Preferred temperature (Ref. 123201): 18.1 - 28.5, mean 27 °C (based on 1087 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00410 - 0.01937), b=2.78 (2.60 - 2.96), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.48 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): Low vulnerability (14 of 100).

Price category (Ref. 80766): Unknown.
