Etymology: Hemiramphus: Greek, hemi = half + Greek, rhamphos = bill, peak (Ref. 45335).
More on author: Günther.

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 31.5 cm SL male/unsexed; (Ref. 9843)
soft rays: 11 - 14;
Vertebrae: 52 - 55. This species is distinguished by the following characters: one dark spot on sides of body (below the dorsal fin); anal-fin rays 11-14 (usually 12-13); dorsal fin with well-developed anterior lobe, pigmented on anterior part; body width 1.3-1.8 times its depth; absence of scales on upper jaw; no preorbital ridge (Ref. 9843).
A coastal species mostly found in more turbid inshore waters replacing Hemiramphus far, which is more common in more oceanic waters (Ref. 9843). Inhabits estuaries (Ref. 75154). A high quality food fish well-known in markets of Brisbane, Queensland (Ref. 9843).

Estimates based on models
Preferred temperature (Ref. 123201
): 15.7 - 20.6, mean 17.9 °C (based on 137 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00188 - 0.00966), 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
): Low to moderate vulnerability (28 of 100).
