Which of these animals has the largest ears?

From bugs to elephants, many animals have evolved large ears as adaptations to hot environments or strategies for finding food. The African elephant has the biggest ears of any living animal. These floppy appendages serve to quickly dissipate heat through the ears’ many blood vessels into the air. Asian elephants live amid the shaded—and cooler—cover of the rainforest, and hence have smaller ears.
