Rhombosoleidae is a family of flatfish, comprising nine genera and 19 species; all members of this family are right eye flounders with asymmetrical pelvic fins. Species are typically demersal, living on bottoms in temperate marine waters on the continental shelf, although some species of Rhombosolea enter fresh water in New Zealand. Most are restricted to waters around Australia and New Zealand, though the Indonesian ocellated flounder, Psammodiscus ocellatus, occurs in Indonesia.
