Short description Morphology | Morphometrics

Dorsal spines (total): 6; Dorsal soft rays (total): 11-12; Anal spines: 0; Anal soft rays: 12. Dark bar under eye; tan in color, with dark spots above; sides with 6-10 vertical bars; large specimens with black margined dorsal and anal fins; caudal fin with oblique bands (Ref. 2798).

Restricted to sandy, quiet water areas and is unable to form burrows where the substrate is disturbed by water movements, is muddy or consists of sand with a particle diameter > 0.5 mm. Food consists of slow moving benthic organisms like chironomid larvae, gastropods, bivalves and amphipods. On exposed shores, they occur deeper than 3.5 m (Ref. 28077, 2798). Occasionally intertidal.

Estimates based on models

Preferred temperature (Ref. 123201): 23.6 - 25.1, mean 24.9 °C (based on 35 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00692 (0.00320 - 0.01497), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.45 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 (10 of 100).
