An elephant's ears have three main purposes:
1. Keep the elephant cooler in hot weather by flapping them. Because their blood vessel are close to the surface, when flapping their ears, the slight breeze cools their blood a little, thus recirculating cooler blood back into their bodies.
2. Obviously, an elephant's ears are for hearing.
3. Finally, when threatened or aggressive, elephants hold their ears out stiffly to the side of the heads and fan them to make themselves look even bigger than they are. This is a display that not only warns other animals, but is meant to intimidate and frighten other aggressors.

∙ 12y agoThey can not only hear from miles, they also give out vibrations...almost like messages. Their hairs that are in their ear are much more fragile making their hearing 10 times better than humans. They can hear better in water as your need more particles for sound waves to travel.

No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes.

Disc brakes are superior in every way.
