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
Hourglass dolphin dolphin does not have a dorsal fin, so the two species are easily distinguished. The fin considerably varies across individuals. It is generally tall and curved, and the curve may be particularly pronounced in older animals. A fully grown adult is about length and weighs . Males are thought to be slightly smaller and lighter than females, although the small number of specimens does not permit a firm conclusion. Like all species of dolphin, they use echolocation to find food and communicate with other members of the their pod. The range is circumpolar from close to the Antarctic ice pack
