Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 14 - 16; Anal spines: 3; Anal soft rays: 9 - 10. Diagnosis: Distinguished from its congeners with the following characters: dorsal-fin rays XI, 14-16 (usually 15); scales above lateral line 10-15 (usually 12-14), below 20-27 (usually 22-25); maxilla scaly; 10 pores on and behind chin, including 1 very small pore near symphysis on each side (may be difficult to detect, obscured by short dense papillae), 2 moderate-sized pores anteroventrally on each dentary, a single large pore ventrally, at articulation of dentary (2 posteriormost usually slit-like and concave), its posterior part scaly; shape of dorsal- and anal-fin rays rounded and slightly angulated, respectively; cluster of very short dense papillae on fleshy lower lip; body often with two indistinct oblique dark bands, the first descending from nape to behind pectoral fin and then running to posterior part of soft anal-fin rays, and the second from base of anterior 3rd or 4th dorsal-fin spine and soft dorsal-fin base, curving backwards through lateral line to upper part of caudal peduncle (Ref. 56360).

Biology     Glossary (e.g. epibenthic)

Inhabits rocky reefs in coastal waters (Ref. 9137) and river mouths; usually over sandy bottoms near rocky shores, from summer to early winter (Ref. 56360).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00772 - 0.02707), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.65 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):  Moderate vulnerability (39 of 100).
Price category (Ref. 80766):   Medium.
