Notes on Different Meanings

The term "billfish" can refer to different specific species in different regions: 1. In a broad biological sense, it often refers to fish in the families Istiophoridae (marlins, sailfish) and Xiphiidae (swordfish). 2. In some contexts, it can refer to other elongated fish with beak-like jaws, such as the gar (referenced in one definition as a "primitive predaceous North American fish"), though this is less common in general usage.
