Turbot (Rhombus maximus), the most highly-valued of the British Flat-fishes. In this genus, to which the Brill (q.v.) also belongs, the eyes are on the left side; the scales are small or absent, the dorsal fin commences on the snout, and the lateral line takes an almost semi-circular curve above the pectoral fin. The turbot when adult is about two feet long, but larger specimens are recorded. It is fairly common round the British and Irish coasts, and the North Sea is one of the best fishing grounds. One species (R. maculatus) occurs on the Atlantic coasts of North America, and another (R. macoticus) in the Black Sea.
