Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 9 - 10; Raggi anali molli: 17 - 19; Vertebre: 33 - 34. Differs from all other species of the genus by the following characters: small size (less than 3.1 cm SL vs. larger than 3.5 cm SL), presence of dark lateral band (vs. absent); flat dorsal edge of the orbit and flat ventral edge of the upper (vs. convex); unequal jaws with the superior jaw longer than the inferior (vs. jaws equal); and mouth subterminal (vs. terminal). Can also be differentiated by its long pelvic fins, reaching the anal-fin origin (vs. short and ends not reaching anal-fin origin), 33-34 vertebrae (vs. 37-43) and 14-16 branched anal fin rays (vs. 21-28).

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=0.00955 (0.00443 - 0.02057), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±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 (10 of 100).
