Predators, Food and Feeding: Natural predators of winter flounder include sharks, oyster toadfish, summer flounder, striped bass, monkfish and spiny dogfish. When feeding, a winter flounder will lie motionless, partly concealed on the bottom, with its head raised off the bottom, braced by the dorsal fin.
Dredge flounder first in flour, then in eggs. Add any remaining flour to cornmeal and mix it up. Dredge fish thoroughly in cornmeal mixture, patting to make it adhere. When oil is popping gently lower in fish and deep-fry 3 to 4 minutes, turning once or twice, until fish comes to surface and is browned and crisp.
