Here's why:
* Size matters: Their ears are massive, acting like giant sound receivers.
* Shape is key: The shape of their ears helps amplify sound waves.
* Movement is crucial: Elephants can move their ears independently, allowing them to pinpoint the direction of a sound.
While they don't have external ear canals like humans, their ears are incredibly effective at picking up low-frequency sounds that travel long distances. This is especially important for communication and detecting danger in their environment.
