Beloniformes (Needle fishes) >
Hemiramphidae (Halfbeaks)
Etymology: Hemiramphus: Greek, hemi = half + Greek, rhamphos = bill, peak (Ref. 45335).
More on authors: Weber & deBeaufort.
Issue
Issue on validity of subspecies: the subspecies Hemiramphus convexus bruuni is elevated at species rank as Hemiramphus bruuni (Parin, Collette & Shcherbachev, 1980) in Eschmeyer (CofF ver. May 2011: Ref. 86870). The species page will be created.
Environment: milieu / climate zone / depth range / distribution range
Ökologie
seewasser; tiefenbereich 0 - 6 m (Ref. 86942). Tropical
Indo-West Pacific: widespread in warmer waters from East Africa to Caroline Islands, New Guinea, New Britain and New Ireland. Replaced in the Red Sea, Arabian Sea and coastal waters in between by Oxyporhamphus convexus bruuni (Ref. 9843).
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm ?, range 14 - ? cm
Max length : 23.0 cm TL Männchen/unbestimmt; (Ref. 10943); 17.6 cm SL (female)
Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 12-15; Afterflossenstacheln 0; Afterflossenweichstrahlen: 14 - 16; Wirbelzahl: 48 - 51. Swim bladder composed of many small compartments instead of a single chamber. Gill rakers on the first arch, 26-33, usually 27-31.
More coastal than O. m. micropterus and frequently found near islands.

50 = 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.
