Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 22 - 27; Vertebrae: 42 - 43. This species is distinguished from most of its congeners by the number of lateral line scales 44-48 (vs. 39-43 or 48-58). It differs from H. beni, and H. dentatus by the number of branched anal-fin rays (22-27 vs. 15-19 and 28-34, respectively); from H. cairoense by the number of scale rows above lateral line (8-10 vs. 6-7); from H. helleri by the number of scales along anal-fin base scale sheath (17-26 vs. 6-12) and the number of scale rows above lateral line (8-10 vs. 7-8); from H. polyodon by the number of caudal peduncle scales (18-20 vs. 16), head length (22.0-26.0 vs. 20.9-22.9% SL), and upper jaw length (45.2-52.6 vs. 43.7-45.6% HL); from H. raqueliae by the number of predorsal scales (15-19 vs. 10-13) and by the number of cusps of first maxillary tooth (3 vs. 5) (Ref. 85819).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00443 - 0.02057), b=3.06 (2.88 - 3.24), 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

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
