In winter a fish's metabolism slows down. Its body temperature sinks to four Celsius and its breathing and heart rates also fall. The cells of most fish contain polyunsaturated fatty acids called omega-3s. These fatty acids contribute to the elasticity of cell membranes, making them more resistant to cold temperatures. So why are fish able to survive a winter under the ice. They take advantage of the special characteristics in their cellular structure and of the special property of water, elasticity.
