Short description
Morfologia | Morfometria
Spine dorsali (totale): 2; Spine anali 0. Head large; the eyes moderately large; the snout moderately long and pointed, its anterolateral margin completely supported by bone. Head ridges strong, supraoccipital scute developed, several similar single-keeled scutes follow on the nape; the underside of the head naked, except for a small patch below the preopercle angle. Body scales covered with dagger-like spinules in 3 to 5 slightly divergent rows. Light organ small, fossa narrow, extending forward immediately before the anus. Overall brownish to swarthy, silvery ventrally; the fins dusky to blackish; the mouth and gill cavities blackish.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
