Bat's Ears and Nose Infogram
While it is known that middle ear ossicle size scales positively with body mass across mammals, and that peak call frequency scales negatively with body mass among bats, there are still large gaps in our understanding of the degree to which allometry or ecology influences the morphology of the chiropteran auditory apparatus.

Many bats, on catching large prey in flight, bring the membrane forward and, by flexing the neck and back, tuck the prey against and into the membrane. With this maneuver the bat takes hold of the victim headfirst and is able to kill or disable it promptly. At rest a bat's head, especially the ears, is its most striking feature.

Other animals. The tragus is a key feature in many bat species. As a piece of skin in front of the ear canal, it plays an important role in directing sounds into the ear for prey location and navigation via echolocation. Because the tragus tends to be prominent in bats, it is an important feature in identifying bat species. The tragus allows echolocating bat species to vertically discriminate.

Abstract. The first steps in frequency analysis by the mammalian auditory system are performed in the cochlea. Hair cells are tuned to a restricted frequency range and the orderly pattern of frequency representation found at all levels of the ascending auditory pathway is laid out in the frequency place code along basilar membrane (BM) length.
