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 transition (14 Ma), with the divergence of odontocetes and mysticetes occurring with the former, and the speciation of delphinioidae with the latter. There is a strong connection between these proteins, the ocean restructuring events, and the echolocation evolution. One specific type of echolocation, narrow-band high frequency (NBHF) clicks, evolved at least four times in groups of odontocetes, including the pygmy sperm whale (Kogiidae) and porpoise (Phocoenidae) families, "Pontoporia blainvillei", the genus "Cephalorhynchus", and part of the genus "Lagenorhynchus". These high frequency clicks likely evolved as adaptation of predator avoidance, as they inhabit areas that have many killer whales and the
