How do bats hunt?

About 70% bats prey on insects, and they usually send out ultrasonic waves to explore their prey, mostly in the air. Bats are very agile in catching prey. Through high-speed photography, it is found that some bats prey directly with their mouths, some intercept their prey with their wings, and some use their tail membranes to scoop worms into their mouths like spoons. There are many ways to hunt.

Bats eat a lot of insects and can eat about one third of the dead insects every night. Many bats in tropical and subtropical regions feed on the fruits of plants. They eat a lot.

There are few carnivorous bats. There may be two kinds of pseudo-vampire bats that often prey on rodents, birds, frogs and lizards [1]. At present, little is known about their behavior, and it is uncertain whether they are active predators.

The only fish-eating bats are Mexican rabbit-lipped bat, Sonora mouse-eared bat and Bigfoot mouse-eared bat. Fish-eating bats are characterized by long legs and big feet, and sharp hooked claws on their toes. When hunting, stick close to the water surface, use ultrasonic waves to detect the waves aroused by small fish, and wait for an opportunity to catch the prey with their feet.

The life habits of honey-sucking bats are similar to hummingbirds. They have evolved features suitable for sucking honey, such as a slender nose and mouth, a suddenly smaller jaw and a slender and malleable tongue. While sucking honey, bats also pollinate plants, especially some plants that open at night (such as gourd trees and cacti).

Extended data:

Bats of Bata suborder have good eyesight and big eyes, and distinguish objects mainly by vision; Members of Bataana usually have degraded vision and small eyes, and mainly rely on echoes to distinguish objects. Some kinds of faces have evolved special structures to increase sonar reception, such as nose wings, wrinkled faces and complex big ears.

As the only flying animal in mammals, bat has a very fast metabolism, which causes various kinds of harm to the body, such as reactive oxygen species, DNA replication errors and so on. But bats live a long life, and some kinds of bats can live for more than 40 years. Studies have shown that there are many genes related to gene repair in bat genome, and the expression level is much higher than that of other mammals.

These DNA repair genes play a significant role in inhibiting virus replication, so although bats carry many deadly viruses, virus replication is seriously inhibited in bats.
