The hakes and burbots is a small family of 21 species found in the Arctic, Atlantic, and Pacific oceans. All species are marine except for the single species of burbot, found in lakes and rivers in northern Europe and North America. They are long, tubular fish with a long dorsal fin that extends almost their whole body length. They have a single barbel on their chin. Many species are commercially fished.
