deskripsi pendek Morfologi | Morfometrik

Can be diagnosed by its unique dorsal color pattern, composed of a uniform gray to light tan or brown color, without strong vermiculations, rosettes or other conspicuous patterns dorsally. This species is tentatively further separated from H. rosai by presenting a slightly more slender tail width at base (holotype tail width 4.5% DW vs. 5.6% DW in holotype of H. rosai), slightly greater preorbital snout length (holotype preorbital snout length 33.2% DW vs. 31.0% DW in holotype of H. rosai), and proportionally smaller pelvic inner length (2.1% DW in holotype of H. gomesi, and ranging from 1.0 to 3.3% DW in all specimens, with a mean of 1.9% DW vs. 4.6% DW in holotype of H. rosai, ranging from 1.3 to 4.9% DW in all specimens, with a mean of 3.7% DW) (Ref. 86515).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).
