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.
