The part of the ear that sticks out and can be seen is called the pinna.
Ears are also used in other ways. African elephants use their large ears to cool themselves when it is very hot. Bats rely on their ears to find prey by echolocation. Some animals use their ears for signalling to each other.
Use of the word[change | change source]
In ordinary language, "ear" refers to this receptor which conducts sound and sends signals to the brain. It does not refer to the many other methods of hearing found in fish and invertebrates. The inner part of the ear is common to most vertebrates, but mammals have special adaptations for hearing which even other land vertebrates do not have. These include the external ear (the pinna) and the three little bones which transmit sounds (the ossicles).
