Fish have several adaptions to survive a winter below the ice First, they are cold blooded meaning their body temperature matches their environment Colder temperatures mean a reduction in their metabolism This slows numerous metabolic processes, such as respiration, digestion, and activity level
Can you freeze a human and bring them back to life?
