Short description
Morfologia | Morfometria
Raggi dorsali molli (totale): 8; Raggi anali molli: 7; Vertebre: 40. This species is readily distinguished from its congeners, except H. beni, by the number of branched anal-fin rays (17 vs. 18-34). It differs from H. beni by the number of lateral line scales (39 vs. 44-53), and by the number of scale rows above and below lateral line (6 and 5 vs. 7-8 and 6-8, respectively); from H. helleri and H. mikrostiktos which have lower branched anal-fin rays (19-23 and 18-21), H. tridens differs by the number of lateral line scales (39 vs. 40-42 and 42-45, respectively) (Ref. 85819).

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=0.00813 (0.00372 - 0.01775), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±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).
