The Gaidropsaridae are a family of cod-like fish that occur in the Atlantic Ocean , as well as with one species each in the southeast and southwest Pacific (near New Zealand and Tasmania).

features

The Gaidropsaridae have an elongated body with a round cross-section and reach lengths of 20 cm to half a meter. The very long dorsal fin supported by segmented fin rays and the long anal fin are striking . In front of the dorsal fin are the rudimentary remains of two other dorsal fin, the first consisting only of a thick, unsegmented fin ray and the second consisting of a short fin ray that supports a short, fleshy ridge sunk into a longitudinal furrow. A single barbel is found on the tip of the lower jaw and two to four others on the nostrils. Other rudimentary barbels may be present.

All Gaidropsaridae live in the sea, most species in the northern Atlantic and its tributaries .

Systematics

The systematic position of the genera and species belonging to the Gaidropsaridae is not undisputed. In Fishes of the World , the standard work of the American ichthyologists Joseph S. Nelson to fish systematics, they belong as a family Gaidropsarinae to fork cod (Phycidae) in the phylogenetic study of the Japanese ichthyologists Hiromitsu Endo they form a subfamily of cod (Gadidae). In the Internet sources Fishbase and Catalog of Fishes, on the other hand, the genera and species are assigned to the tadpole family (Lotidae) without forming a separate subfamily. In the revision of the bony fish system by Ricardo Betancur-R. and colleagues they have family rank.
