Which outcome occurs when a marine mammal enters tropical waters during a period of prolonged exertion?

💡 Explanation

When a marine mammal exerts itself in warm tropical waters, peripheral vasodilation occurs because blood flow increases to the skin, dissipating excess heat into the water. Therefore heat dissipation results, rather than cold generation or heat retention which the animal normally uses to reduce heat loss in cold environments.
