Short description Morfologia | Morfometria

Spine dorsali (totale): 11; Raggi dorsali molli (totale): 25-29; Spine anali 2; Raggi anali molli: 7. Eye small, 11 to 16 % of head length; snout bluntly rounded; no barbel on chin; teeth differentiated into large and small in both jaws; gill rakers slender, about half the length of gill filaments at angle of arch, 10 to 13 on lower limb. Second anal spine long, stiff, 45 to 54 % of head length. Scales on head and throat cycloid (smooth). Swim bladder hammer-shaped, with about 12 pairs of arborescent appendages along its sides, the first entering head and sending a palmate branch to the front of the pectoral arch. Sagitta (large earstone) with a tadpole-shaped impression, the head of which has its long axis lying obliquely to that of sagitta and the tail expanded and deepened as a hallow cone connected with the head by a narrow groove.

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 28.3 - 29, mean 28.8 (based on 52 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00473 - 0.02021), b=3.07 (2.91 - 3.23), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilienza (Ref. 69278):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
