Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 13 - 14; Spine anali: 3; Raggi anali molli: 14 - 15. Pectoral filaments 3; fin membranes uniformly brown like all other fins. Vomer lacks deciduous tooth plates on both sides throughout its life history. Posterior part of maxilla shallow, 2-3% of SL. Long tooth plate extension onto lateral surface of lower jaw, 9-10% SL (Ref. 41639).

Too small to be of major commercial importance (Ref. 57343).

Estimates based on models

Preferred temperature (Ref. 123201): 28.7 - 29.4, mean 29 °C (based on 381 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00308 - 0.01483), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Price category (Ref. 80766): Very high.
