Aulopidae

The Aulopidae are a small family of aulopiform ray-finned fish. They are found in most tropical and subtropical oceans, such as the Atlantic, Mediterranean, and Pacific. The aulopids are commonly known as flagfins.

genus of fishes

Aulopus is a genus of flagfins native to the Atlantic Ocean and the Pacific Ocean. Although Aulopus is native to both the Atlantic and the Pacific oceans, for the first time in 2010 Aulopus filamentosus (the royal flagfin), was spotted in Brazilian waters. A discovery like this may suggest that these fish can be found in new environments.
