Which outcome occurs when a marine mammal dives into icy water and surface blood vessels experience dramatic vasoconstriction?

💡 Explanation

Reduced heat loss occurs because vasoconstriction near the skin's surface decreases convection and thus reduces thermal conduction of blood to the cold ocean, therefore minimizing heat expenditure, rather than increased supply to extremities during aquatic exposure.
