Elephants As the largest land animal on earth, elephants rely on their huge pair of ears. Simply by tapping their ears, elephants can lower their body temperature by 12℃ or more. Moreover, elephants often open their ears when facing the wind to reach this cooling effect. Dogs The dog’s way of escaping the heat is probably the most common in our daily lives--sticking their tongues out.
