Physical 

The smallmouth founder is a left-eyed flatfish, which means that when they mature, their eyes will be on the left side of their body. Their body is olive brown with darker splotches, and 2-3 blotches on their fins. Their underside, or blind side, is white. Adults grow up to 5 in (12.7 cm). They received their common name due to the small size of the mouth in relation to the rest of the body, as compared to other flounders.

Habitat

Smallmouth flounder are transient to the Barnegat Bay (they migrate into the Bay for part of the year). Their range spans from Massachusetts to North Carolina, with occasional appearances in South Carolina to Florida and the northern Gulf of Mexico. Smallmouth flounder live in coastal waters, channels, and prefer sandy or muddy bottoms.

Feeding 

Not much is known about smallmouth flounder diets specifically. However, flounders generally burrow into the sediment to disguise themselves from prey.
