The Egyptian fruit bat or Egyptian rousette (Rousettus aegyptiacus) is a species of megabat that occurs in Africa, the Middle East, the Mediterranean and the Indian subcontinent. It is one of three Rousettus species with an African-Malagasy range, though the only species of its genus found on continental Africa.
The Egyptian fruit bat is the only megabat whose range is mostly in the Palearctic realm; [113] it and the straw-colored fruit bat are the only species found in the Middle East. [113] [114] The northernmost extent of the Egyptian fruit bat's range is the northeastern Mediterranean. [113] In East Asia, megabats are found only in China and Japan.
Pteropus (suborder Yinpterochiroptera) is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. [3]
Rousettus is a genus of Old World fruit bats or megabats, referred to as rousette bats. The genus is a member of the family Pteropodidae. The genus consists of seven species [1] that range over most of Africa to southeast Asia, and the islands of the south Pacific.

Microbat calls ⓘ range in frequency from 14,000 to over 100,000 hertz, well beyond the range of the human ear (typical human hearing range is considered to be from 20 to 20,000 Hz). The emitted vocalizations form a broad beam of sound used to probe the environment, as well as communicate with other bats.
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight. Bat species account for about 20% of all mammals. Family: Pteropodidae (flying foxes, Old World fruit bats) Subfamily: Pteropodinae. Genus: Rousettus. Egyptian fruit bat, R. aegyptiacus LC [8] Family ...

Therefore, compared to a terrestrial mammal of the same relative size, the bat's heart can be up to three times larger, and pump more blood. [80] Cardiac output is directly derived from heart rate and stroke volume of the blood; [81] an active microbat can reach a heart rate of 1000 beats per minute. [82]
