Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Spine anali: 0; Raggi anali molli: 8 - 11; Vertebre: 33 - 38. Diagnosis: body cylindrical; tooth patches narrow; vertically oriented pectoral fins, placed near body mid-depth; 6-7 branched caudal-fin rays; pectoral-fin rays usually 8, rarely 7 or 9; 34-38 vertebrae; eyes relatively small, interorbital space relatively broad; caudal saddle and bar pattern quite distinct in juveniles and young and usually apparent in adults (Ref. 44050), but often subdued (Ref. 81645). Dorsum and flank nearly always spotted, sometimes extensively (Ref. 44050, 81645). Commonly 10-15 gill rakers on first arch (total range 4-22)(Ref. 44050). Caudal saddle and anal-fin pigmentation not continuous (Ref. 44050, 81645). Venter often dusky, occasionally lightly spotted (Ref. 81645).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00451 - 0.02792), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
