The flagtails (āhole[4] or āholehole[5] in the Hawaiian language) are a family (Kuhliidae) of centrarchiform ray-finned fish of the Indo-Pacific area.

The genus Kuhlia is named for the German zoologist Heinrich Kuhl (1797–1821).

[6] The distinctive characteristic of these fish is a scaly sheath around the dorsal and anal fins.

Their bodies are compressed and silvery, and they tend to be small, growing to 50 cm at most.

During the day, they usually school, dispersing at night to feed on free-swimming fish and crustaceans.
