Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 9; Raggi anali molli: 28 - 34; Vertebre: 34. A thin band of dark pigmentation present from dorsal to the anal fin base (lacking in H. macrolepis). Differs from H. virgulatus where this band and the longitudinal band extending from the posterior portion of the head to the caudal fin base is thicker and more heavily pigmented. Further, this species differs from H. virgulatus with its relatively smaller orbital diameter; more pointed posteroventral corner of preopercle; relatively elongate gill rakers along the epibranchial and hypobranchial portion of the first branchial arch; single ossification in the position primitively occupied by infraorbitals 4 and 5; small posterior dentary teeth beginning behind lateralmost tooth of the anterior row thus not forming a second internal teeth series (Ref. 38319).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.6 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).
