Short description Morfologia | Morfometria

Spine dorsali (totale): 19; Raggi dorsali molli (totale): 14-15; Spine anali 2; Raggi anali molli: 12 - 13; Vertebre: 34. Body moderately elongate and compressed. Two lateral lines, the lower originating below the 6th to the 7th spine of the first dorsal fin, descending sharply to ventral contour of body, dividing into a short anterior branch and a much longer posterior branch. The pelvic fin represented by 1 spine and 2 tiny soft rays in smaller specimens but entirely absent in specimens over 10 cm SL. Body color is brownish, fins hyaline; first dorsal fin with a black blotch distally on two anterior membranes.

Estimates based on models

Preferred temperature (Ref. 123201): 13.8 - 17.6, mean 17.2 °C (based on 13 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00166 - 0.00830), 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):  3.8   ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
