Fruit bats are animals belonging to the genus Pteropodidae. They are mainly distributed in the tropics and subtropics. There are not many species in China, which are limited to the provinces of southern China, and are now suspected of being the host of Ebola virus. Fruit bats are the largest bats. Some species have wings as long as 2 meters and are also known as flying foxes. It is large in size, with claws on the first and second fingers. The eyes are large and the tail is short, not covered by the film. Going out for food at dawn and dusk, the sap in the fruits and stamens will cause certain harm to the fruit trees. The ear shells of fruit bats are simple, ovoid, and the ear edges are connected into a circle. There is no tragus and antitragus; the eyes are developed and the vision is good; the skull has a long muzzle, the posterior edge of the palate exceeds the molars, and the crown of the molars is flat and the center is The longitudinal groove is suitable for soft food; the tongue is very developed, and the types of pollen and nectar are particularly prominent, which can extend far outside the mouth.

There are nine species of fruit-eating bats in the Philippines, which mainly live in virgin forests and are highly dependent on the plant resources in the forest. Therefore, human development of forests as farmland or excessive use of natural products of forests will seriously affect habitat. The diet of fruit-eating bats in the Philippines is quite extensive. Almost all species are widely eaters, not just one or two kinds of fruit. However, different species of fruit-eating bats have different emphasis on fruit selection. The height of fruit trees and the fruit density per unit area (such as a tree) are different from the large fruit-eating bats that fly long distances to "sit and eat". The words are more important. The small and medium-sized fruit-eating bats that go back and forth frequently use the color of the fruit as the selection object. Therefore, most of the fruits eaten by large fruit-eating bats are green or dark, while small and medium-sized fruit-eating bats are mainly fruits with bright colors, higher protein, fat, and sugar.

Flying foxes are actually a kind of fruit bats. They are called flying foxes because their heads are like foxes and have brown-red fur. The long-tongued fruit bat is a new species of flying fox with orange-red fur and three white stripes on its face. It was found on the island of Mindoro in the Philippines. This flying fox was first named the Mindoro fruit bat, which researchers believe is a unique animal species in the Philippines. Also known as the cave fruit bat, its forearm is 6.1 to 7.8 cm in length, and its skull is 3.2 to 3.7 cm in length. It is a larger type of fruit bat. The tongue is very long and has a special elongation ability. Without tragus, the edge of the ear shell is connected into a complete ring. The head is dark brown, the front shoulders are light white and gray, the back is dark brown, and the lower part is brown. The wing membrane is dark brown and black, the second finger of the forelimb has no claws, and the wing membrane on both sides of the forearm has fine villi. The interfemoral membrane is narrow, the tibia is exposed, the distance is obvious, with a short tail, the skull is thicker, the kiss is shorter, and the posterior orbital protrusion is prominently developed. There are 5 cheek teeth on each side, and the tooth gap between the inner two incisors is significantly smaller than the tooth gap between the inner and outer incisors. It lives on dense trees during the day and feeds on fresh fruits such as banyan fruit and bananas. It is distributed in the west, south and southeast of Yunnan, and southwestern Guangxi, China.
