Fish called sole, flounder, turbot, dab and halibut all belong to the same unique family of flatfish. These fish all have oval shaped bodies, dark on top, light on bottom and odd looking eyes on the same (top) side of their heads. They are bottom dwellers, propelling themselves with a wave like motion along the sandy bottom of the sea. With the exception of halibut, and some large flounders and turbots, most are small, in the 1 to 3 pound range. The different species vary greatly in quality, taste and texture.Sole and flounder are harvested on both the East and West Coast, as well as the Gulf of Mexico. Along the East Coast, Summer flounder is the most abundant, and can weight up to 20 pounds.
