Hemiramphidae is a family of fishes commonly known as halfbeaks, spipe fish, or spipefish. They are a widely distributed and populous group of epipelagic fish that inhabit warm waters worldwide. The halfbeaks derive their name from their unique jaw structure, characterized by lower jaws that are substantially longer than their upper jaws. Additionally, the viviparous halfbeaks, which bear live young, have frequently been categorized within this family.
