Soles

Distribution: Primarily Europe to Australia and Japan. Both eyes on the right side of the head. Margin of preoperculum completely concealed (covered by skin and scales). Dorsal fin origin above or before eyes; pectoral fins present or absent; no fin spines. Dorsal and anal fins free from caudal fin or united with caudal fin. Pelvics free from anal fin. Soles are benthic, neritic fishes, some of considerable economic importance. The taxonomy of this family needs revision.
