Description

The California halfbeak is a small surface fish of the halfbeak family (Hemiramphidae) from the eastern Pacific. The species grows to about 15 cm and has a slender, silvery body with the greatly elongated lower jaw characteristic of halfbeaks, while the upper jaw stays short. Adults stay near shore, often in coastal bays at or just below the surface, and form small schools. As an omnivore it feeds on drifting plant matter, small invertebrates and plankton. Owing to limited data the species is assessed as Data Deficient (DD). It is harmless to humans.
