Which thermoregulatory outcome occurs when a seal enters warm water, after prolonged exposure to Arctic conditions?

💡 Explanation

When a seal, adapted to Arctic waters, encounters warmer temperatures, peripheral vasodilation occurs because the blood vessels near the skin surface expand, facilitating heat dissipation into the warmer environment. Therefore increased vasodilation occurs, rather than reduced metabolic output, increased shivering, or countercurrent heat exchange, which are mechanisms to conserve heat in cold conditions.
