Fish are cold-blooded animals, which means that the lower the temperature of their surrounding space, the more difficult it is for them to maintain their metabolic functions. However, arctic fish do not freeze in cold sea waters. Their body contains antifreeze substances (protein) that prevent the formation of ice crystals in their blood. Protein slows down water molecules, which are usually in a state of continuous movement, this prevents the formation and breaking of bonds that are necessary for the formation of ice.
