Bothidae

Lefteye flounders are a family, Bothidae, of flounders. They are called "lefteye flounders" because most species lie on the sea bottom on their right sides, with both eyes on their left sides. A helpful reminder when trying to recall the family name for this fish is that "Bothidae (Both o' dey) eyes are on the same side o' dey head." The family is also distinguished by the presence of spines on the snout and near the eyes.

Lefteye flounders vary considerably in size between the more than 160 species, ranging from 4.5 cm (1.8 in) to 1.5 m (4.9 ft) in length. They include such economically important species as the Japanese halibut.
