How the cell membrane structure of an arctic fish differ from tropical fish?

Arctic fish have a cell membrane structure that contains more unsaturated fatty acids to remain fluid in colder temperatures, while tropical fish have a higher proportion of saturated fatty acids to provide stability in warmer waters. Additionally, arctic fish may have specialized proteins in their membranes to help regulate their internal temperature in extreme cold environments.
