Auricle (anatomy)
Videos
The auricle or auricula is the visible part of the ear that is outside the head. It is also called the pinna, a term that is used more in zoology.
The fennec fox uses its distinctive oversized pinnae to radiate excess heat and to amplify the sound of small prey burrowing under the desert sand.
To an impala, the pinna is useful in collecting sound.
