Wikipedia Abstract

The weakfish, Cynoscion regalis, is a marine fish of the drum family Sciaenidae.A large, slender, marine fish, it is found along the east coast of North America. The head and back of this fish are dark brown in color with a greenish tinge. The sides have a faint silvery hue with dusky specks, and the belly is white. The origin of its name is based on the weakness of the mouth muscles, which often cause a hook to tear free, allowing the fish to escape.
