The Aulopidae are a small family of aulopiform fish. They are found in most tropical and subtropical oceans, and are commonly known as flagfins.
The aulopids resemble lizardfishes in appearance, and range up to 60 cm (24 in) in length. They have large dorsal fins, the first ray of which is greatly extended. They are bottom-dwelling fish, living at depths of 1,000 m (3,300 ft).
