Just about everything in the icy waters off the coast of Antarctica is in the same state—frozen. Yet one type of fish, called a notothenioid, remarkably does not freeze in the frigid environment. In a recent study, scientists were able to better understand a genetic alteration in the fish. As it turns out, antarctic notothenioids produce a substance that acts as antifreeze. Antifreeze is a term familiar to car owners. It is a substance that keeps the water inside an automobile engine from freezing. Notothenioids manufacture their own "antifreeze proteins." These proteins lock on to ice crystals in their blood.
