Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 15; Anal spines: 0; Anal soft rays: 10 - 13; Vertebrae: 52 - 57. Greatly prolonged, beak-like lower jaw; upper jaw short, triangular and without scales; preorbital ridge absent; total number of gill rakers on first gill arch 33-46; pectoral fins long, reaching beyond anterior margin of nasal pit when folded forward; no spots or vertical bars on sides.

Biology     Glossary (e.g. epibenthic)

Inhabits coastal waters rich in vegetation (Ref. 5213). Found more offshore than other species of Hemiramphus in the western central Pacific; juveniles and immature individuals are relatively common far from shore, usually among floating plants (Ref. 9843). Caught by set-net.

Estimates based on models

Preferred temperature (Ref. 123201): 24.3 - 29.3, mean 28.4 °C (based on 3275 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00193 - 0.00988), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.5 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):  Moderate vulnerability (39 of 100).
Price category (Ref. 80766):   Medium.
