flounder a name which originally referred to Platichthys flesus, a flatfish of the E. Atlantic, ranging from the White Sea down to the Mediterranean. This is a dextral flatfish (i.e. both eyes are on its right-hand side), but it occurs not infrequently in reversed form (i.e. eyes on the left-hand side). Reversed specimens can cause considerable puzzlement in the fish markets, although not as much surprise as the appearance of a completely albino flounder, white on both sides and equipped with pink eyes and fins, such as was once taken on the coast of Norfolk.
