[39]: 48 Despite the fact that body size was a defining characteristic that Dobson used to separate microbats and megabats, not all species of megabat are larger than microbats; the spotted-winged fruit bat (Balionycteris maculata), a megabat, weighs only 14.2 g (0.50 oz). [35]
The megabats, including flying foxes, have the greatest encephalization quotient (brain size relative to body size) of any bat family at 1.20. [20] This value is equivalent to that of domestic dogs. [21] Flying foxes display behaviors that indicate a reliance on long-term information storage.
Fruit bats, also known as flying foxes or megabats, are the 197 species of bats that make up the suborder Megachiroptera, found throughout the tropics of Africa, Asia, and Oceania, of which 186 are extant. The suborder is part of the order Chiroptera (bats), and contains a single family, Pteropodidae.
[28] [29] [30] Megabats like the hammer-headed bat tend to be over-sampled relative to other potential Ebola virus hosts, meaning that they may have an unwarranted amount of research attention, and as of 2015, no bat hunter or researcher is known to be the index case ("patient zero") in an Ebola outbreak.
The giant golden-crowned flying fox (Acerodon jubatus), also known as the golden-capped fruit bat, is a species of megabat endemic to the Philippines.Since its description in 1831, three subspecies of the giant golden-crowned flying fox have been recognized, one of which is extinct.
Horsfield's fruit bat is a medium-sized megabat, intermediate in size between flying foxes and pygmy fruit bats.Adults weigh around 55 to 60 grams (1.9 to 2.1 oz), and have light-grey to brown fur, with a reddish-brown or orange mantle around the shoulders.
The large flying fox (Pteropus vampyrus, formerly Pteropus giganteus), also known as the greater flying fox, Malayan flying fox, Malaysian flying fox, large fruit bat, kalang, or kalong, is a southeast Asian species of megabat in the family Pteropodidae. [3]
Spotted-winged fruit bats are unusually small megabats, with a head-body length of 5.2 to 6.2 centimetres (2.0 to 2.4 in), [2] a wingspan of 28 centimetres (11 in), and an adult body weight of around 13 grams (0.46 oz). Most of the head and body are covered in thick blackish-brown fur, while the underparts are a pale grey-brown.
