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
Animal echolocation rats can use echolocation to navigate mazes. Echolocation systems are susceptible to interference known as echolocation jamming or sonar jamming. Jamming occurs when non-target sounds interfere with target echoes. Jamming can be purposeful or inadvertent and can be caused by the echolocation system itself, other echolocating animals, prey, or humans. Echolocating animals have evolved to minimize jamming; however, echolocation avoidance behaviors are not always successful. "Galleria mellonella" exhibits predator avoidance behaviors such as dropping, looping, and freezing when emitters sent out ultrasound waves, indicating that "G. mellonella" can both detect and differentiate between ultrasound frequencies used by predators or from
