Greenland sharks have a unique adaptation that helps them stay warm in the frigid Arctic waters: they possess a high concentration of urea in their blood, which acts as an antifreeze and helps regulate their body temperature. Additionally, their slow metabolism and large body size reduce energy expenditure, allowing them to conserve heat more effectively. Their thick layer of fat also provides insulation against the cold. Together, these adaptations enable them to thrive in extreme environments.
