Open encyclopedia reference
Hemiramphus depauperatus, commonly known as the Polynesian halfbeak (or “Demi-bec polynésian” in French and “IheIhe” in Native Hawaiian) is a species of fish, belonging to the family Hemiramphidae found in the Pacific Ocean. The species was first misidentified as Hemiramphus eclancheri by Alvin Seale in 1906, further identified by Henry Weed Fowler to be considered Hemiramphus brasiliensis. It has since been corrected to Hemiramphus depauperatus.
