(The Egyptian fruit bat Rousettus egyptiacus is an exception, but does not use the larynx echolocation method of microbats, instead giving scientists the theory that it clicks using its nasal passages and back of its tongue.) Microbats lack the claw at the second finger of the forelimb.
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.
They are small bats, from 4 to 8 centimetres (1.6 to 3.1 in) in body length, and with grey, brown, or reddish fur. The skull is distinguished by a characteristic interorbital concavity, externally connected to a long slit that runs down the centre of their faces from between the eyes to the nostrils, and probably assists in echolocation.
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.
The skulls of Pteropus species are composed of 24 bones, the snout is made of 7, the cranium of 16 and the mandible is a single bone. It has a large and bulbous braincase. Like all mammals, flying foxes have three middle ear ossicles which assist in transmitting sound to the brain. Flying fox skulls continue to develop after they are born.
An Egyptian fruit bat (Rousettus aegyptiacus) carrying a fig. Fruit eating, or frugivory, is found in both major suborders. Bats prefer ripe fruit, pulling it off the trees with their teeth. They fly back to their roosts to eat the fruit, sucking out the juice and spitting the seeds and pulp out onto the ground.
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 ...
