Short description
Morfologia | Morfometria
Spine dorsali (totale): 0; Raggi dorsali molli (totale): 7; Spine anali 0; Raggi anali molli: 8 - 11. Diagnosis: caudal peduncle long and moderately compressed, narrowest at base of caudal fin (Ref. 57128). Caudal-peduncle length comprised 4.5-5.2 times in standard length, its depth comprised 2.5-4 times in its length (Ref. 57128, 81646). Distance from head to dorsal fin 0.7-1.0 times the head length; posterior nostrils at same distance from eyes than anterior nostrils from snout tip (Ref. 57128).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±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).
