Hemiramphidae (Halfbeaks)
Etymology: Oxyporhamphus: Greek, oxy = sharp + Greek, rhamphos = bill, peak (Ref. 45335).
More on authors: Weber & deBeaufort.
Taxonomic Remarks
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.

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).
