Bats have various eating habits. Some species like nectar and fruit, others like to eat fish, frogs and insects, suck animal blood and even eat other bats. Generally speaking, big bats generally feed on fruits or nectar, while small bats mostly prey on insects.

There are all kinds of bats. They eat everything: including fruit, fish, pollen and even blood. Most bats prey on insects when flying at night, and each bat can distinguish its own sound waves, indicating that even if they prey with other bats, they will not be disturbed by other sound waves.

Bats that feed on insects have echolocation systems to varying degrees, so they are called "live radars". With the help of this system, they can fly and catch food in a completely dark environment, and send out wave signals by echolocation under a lot of interference without affecting normal breathing.

There are structures called "nasal lobes" on the nose and mouth of their heads, and there are complex special skin folds around them. This is a peculiar biological wave device, which has the function of transmitting waves and can continuously emit high-frequency biological waves.

If you encounter obstacles or flying insects, these biological waves can be reflected back and then received by their extraordinary big auricles, so that the feedback information can be analyzed in their tiny brains. This kind of biological wave detection sensitivity and resolution are extremely high, so that they can not only identify the direction and locate their own flight path according to the echo, but also identify different insects or obstacles for effective avoidance or pursuit.

Bats can fly freely in the air with accurate echolocation and incomparably soft skin membrane, and even fly in a dexterous curve, constantly changing the direction of waves to prevent insects from interfering with their information systems and trying to escape.

living environment

Bats live in caves, ceilings, partitions, tree holes and crevices in ancient buildings, while some fruit-eating bats in the south still hide behind the leaves of palm trees and banana trees. Some bat populations have thousands of bats together, some bats live together, and some bats live separately.

Many bats living in the forest migrate to warm areas in winter, sometimes flying thousands of miles. Cave bats in temperate zones usually hibernate. Bats breed only once a year. In the early warm season, bats will give birth.

Extended data

Bats are the only animals that can really fly. Although they don't have the feathers and wings like birds, and their flying ability is much worse than birds, their forelimbs are very developed, and their upper arms, forearms, metacarpals and phalanges are particularly long. From the end of phalanges to the humerus, sides, hind legs and tail are covered with a thin and hairy skin, forming a unique flying organ of bats-Chiropterus.

There are also records about bats in ancient China. They also lived in stalactite caves called fairy rats. Bats there can live forever because they can drink water from caves. After thousands of years, their body color has also changed greatly, from the initial dark color to white.

Bats use waves to judge whether there are obstacles ahead, thus changing their flight paths. In the past, many people said that bats had poor eyesight, but it was actually a big misunderstanding. Many scientists point out that bat's eyesight is not bad, and different kinds of bats have different eyesight. The use of ultrasound by bats is not necessarily related to their eyesight.
