Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 11 - 12; Raggi dorsali molli (totale) : 15 - 17; Spine anali: 3; Raggi anali molli: 15 - 17; Vertebre: 28. This robust species is of moderate size (4.8-9.4 cm SL) possess the following set of features: upper jaw sexually dimorphic, longer in adult males; a black stripe on the inner lining of maxilla and adjacent membranes; D 15-17, A III; 21-24 gill rakers on lower limb of first arch; multifid nasal cirrus in adults; upper margin of subopercle is extended dorsally as a broad membranous flap; presence of a small black spot at tip of first and second dorsal-fin spines, no ocellated dorsal-fin spot (except in juveniles); body with 6 wide brown bars, usually discontinuous with corresponding markings on dorsal fin, but not below midline; 17 (rarely) or 18 caudal vertebrae (Ref. 75633).

Specimens collected with ichthyocides (Ref. 75633).

Estimates based on models

Preferred temperature (Ref. 123201): 20.6 - 27.7, mean 22.9 °C (based on 14 cells).

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

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
