Red snapper, red drum and red mullet are all similar fish and are often confused by most of us, but there are slight differences. Red snapper is easy to distinguish with its red and pink hues on the exterior and its eyes will also look red. Red drum, also called red fish, can be found in the Gulf waters of northern Mexico to Florida and also from Florida up to Massachusetts on the Atlantic side. Red drum, or channel drum as it's often called, have a spot on near their tail that resembles an eye that tricks predators. Red mullet, also called rouget, can be found in the north Atlantic and the Mediterranean where it is considered a delicacy. These smaller fish are caught using trawl nets.
