Megabat Megabat Megabats constitute the family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or, especially the genera "Acerodon" and "Pteropus", flying foxes. Megabats are found in tropical and subtropical areas of Eurasia, Africa, and Oceania. Compared to insectivorous bats, fruit bats are relatively large, and with some exceptions, do not navigate by echolocation. They are herbivores and rely on their keen senses of sight and smell to locate food. Most fruit bats are larger than insectivorous bats or Microchiroptera, but a number of small fruit bats exist, also. The smallest species is
Long-legged bat family Phyllostomidae that use low-intensity “whispering” echos, the Long-Legged Bat has been shown to produce high-intense echolocation calls to detect its prey. M. macrophyllum will adjust the intensity of its calls depending on the environment that it’s in. When in areas with high acoustic clutter, the bats will decrease their signal intensity, while in more open areas, the bats will increase their signal intensity. By increasing call intensity in a more open environment, this allows these bats to have a broader detection range for food. Average intensity output has been shown increase by 11 dB, corresponding to a 4x amplitude
