The beaked fish (Percophidae in the traditional sense) ( Greek , perke = perch, ophis = snake; Syn .: Bembropsidae) live in the Atlantic , in the Indian Ocean , in the western and south-eastern Pacific . The fish live on the sea floor, on the continental shelf at depths of 100 to 400 meters. The beakfish are not a natural family group.

features

Most species are big-eyed, their heads are flat, the body elongated and spindle-shaped. The eyes are close together on the top of the head and almost touch, the lower jaw protrudes. They have separate hard-nosed and soft-nosed dorsal fins ; in some species the dorsal fin with a radial structure is absent. The ventral fins are throaty. Beak fish grow to be three to 25 centimeters long.

Systematics

There are almost 50 species, which are assigned to eleven genera and three subfamilies.

The Bembropinae were in the current revision of the bony fish systematics by Betancur-R. and colleagues raised to the rank of an independent family within the perch-like (Perciformes). Odani and colleagues, on the other hand, gave three autapomorphies for a relationship between the Bembropinae and the Percophinae, but could not name any autapomorphies for the monophyly of the Percophidae (i.e. the inclusion of the Hemerocoetinae).

In 2015, the Hemerocoetinae were also raised to the family rank (order Pempheriformes) after the relationship of Percophis brasiliensis to the Antarctic fish (Notothenioidei) had been recognized and the former was thus assigned to the perch-like like the Bembropidae. This means that Percophis brasiliensis is now the only species in the Percophidae family.
