Short description Identification keys | Morphology | Morphometrics

Belongs to the pogonognathus - group which differs from Hemirhamphodon pogonognathus and the other species of Hemirhamphodon in having 1 two distinct sizes of melanophores in the dorsal fin, large and small. Resembles species of the phaiosoma -group but differs sharply from H. pogonognathus in having a continuous band of pigment extending from the distal part of the fin to its base (Ref. 26761).

Females bear live young (Ref. 58777).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00200 - 0.01044), b=3.03 (2.82 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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