121 What do bats eat, what do bats eat?

Feeds mainly on flies and beetles. There are also bats that eat fruit, fish, frogs or pollen. What's even more terrifying is that there are bats that specialize in sucking the blood of animals, and these bats are relatively large.

The most common bat is to eat nocturnal insects such as moths.

But in fact, depending on the species and distribution area, they also eat small birds, small frogs, fish, and plant fruits (there is a kind of bat that eats fruit in the National Geographic magazine in the BCI issue). And, of course, vampire bats that feed on animal blood.

Generally omnivorous.

Bat animals have a wide range of diets, some species like nectar, fruits, others like to eat fish, frogs, insects, suck animal blood, and even eat other bats. In general, large bats generally feed on fruits or nectar, while most small bats mainly prey on insects.

Insects-feeding bats have echolocation systems to varying degrees, hence the name "living radar". With this system, they are able to fly and catch food in complete darkness, use echolocation in the face of heavy distractions, and emit ultrasonic signals without affecting normal breathing. They have a structure called "nasal lobe" on the mouth and nose of their head, and there are very complex special ** folds around it, which is a peculiar ultrasonic device, which has the function of emitting ultrasonic waves, and can continuously emit high-frequency ultrasound waves.

If they hit an obstacle or a flying insect, these ultrasound waves can be reflected back and then picked up by their extraordinarily large pinna, allowing the feedback to be analyzed in their tiny brains. This ultrasonic detection sensitivity and resolution are extremely high, so that they can not only determine the direction and locate their flight path according to the echo, but also distinguish different insects or obstacles, and effectively avoid or hunt them. Relying on accurate echolocation and incomparably soft membrane, bats hover freely in the air, and can even use dexterous curves to fly, constantly changing the direction of ultrasonic waves to prevent insects from interfering with its information system and attempting to escape.

Like other animals, many bats are becoming less and less common in nature and are becoming extinct. Poisons used to destroy insects and wood protection agents kill them when they hibernate in hibernation, and many misconceptions have led humans to hunt them down in large numbers. Some species inhabit hollow trees that have been cut down, and the ruins have been demolished or rebuilt to perfection, rendering them unviable.

Bats play a very important role in maintaining the ecological balance of nature, all kinds of insectivorous bats can eliminate a large number of mosquitoes, noctuidas, beetles, nuns and other pests, and can prey on more than 3,000 in one night, which is beneficial to humans. The manure collected by bats is also a good fertilizer and useful for agricultural production. Processed bat droppings are called "luminous sand" and are a type of traditional Chinese medicine.

Bats are also an important object of study of animal orientation, positioning and dormancy, and the secrets of their radiation technology have not yet been fully understood, and humans only know what bats can do, but still do not know how they do it, so it is imperative to save those endangered species.

Bats are usually seen and feed mainly on flies and beetles. There are also bats that eat fruit, fish, frogs or pollen. There are also bats that specialize in sucking the blood of animals, and these bats are relatively large.

The bats we see are very small, and if they feed on flies and Coleoptera, they also eat raw fruits, fish, and 3

-./ " " \.Bats eat mosquitoes are the favorite, but there are some who are taught to eat special fruits and suck blood.

I feel that bats only eat flying insects. I saw it in my hometown countryside.

Bats eat fruits, fish, pollen, and even blood. Most bats hunt insects when flying at night, and each bat can recognize its own sound waves, which means that even if it hunts with other bats, it will not be disturbed by other sound waves.

70% of bat species feed mainly on insects and other arthropods; The rest of the species feed mainly on fruits, nectar, and pollen. Some tropical species are carnivorous, and there are 3 species of vampire bats that feed on blood.

The shape of a bat's skull and teeth is mainly related to the food it eats. The omnivorous leaf-mouthed bat and the insectivorous round-eared bat (tetraeared bat) have the most common teeth to chew food, while the large fruit-eating bat has large, flat molars. Tailless long-tongued bats that feed on nectar rarely use their teeth, however their skulls are elongated to accommodate a long, hairy tongue.

The chisel-like incisors and the vertical flattened razor-like upper canines were used to bite into a grooved incision in the animal** so that it could lick the blood inside. Carnivorous false vampire bats have huge skulls, strong, sharp canine teeth and scissor-like sun teeth that can be sliced and fleshed.

Food such as mosquitoes, stone moths and moths, hunt at an altitude of 20 to 40 meters, and if food is scarce, sometimes move all night to prey on gnats and other harmful insects. Usually females and males live together, but during pregnancy and lactation females live in groups of 40 to 50, while males inhabit individually or in small groups.

The main natural enemies of common bats are mainly snakes, lizards, etc. Its overwintering is unknown, but it hibernates. During hibernation, it is only hung on the top of the cave or lodging on the rock wall, and is mostly distributed in the depths of the cave, the temperature in the cave is 7, and the body surface temperature is close to the air temperature.

Activity characteristics. The body temperature of bats varies greatly, up to 56 (due to the fact that some large fruit eaters have a relatively constant body temperature due to their different physiological and behavioral characteristics, while the vast majority of small insectivorous bats are typical isotherms).

It has been observed that bats living in temperate zones spend much more time inactive than active in their lives, sleeping almost all day and part of the night in summer, and some species when the weather is cold, like birds, carry out long-distance seasonal migrations to the south to spend the winter, and those that remain in place enter a long period of hibernation during the harsh winter.

According to incomplete statistics, the big-eared bats and northern brown bats that inhabit the vicinity of Leningrad spend only 1 15 1 20 of their active time in their lifetime, and the rest of the time they sleep (Kugakin, 1959).

Bats feed on insects.

Most bats feed on insects, play an important role in the balance of insect reproduction, and may even help control pests. Some bats also eat fruits, pollen, nectar, bats are pterocods, pterocods are the second largest group of animals after rodents, is the only class of mammals that have evolved to truly have the ability to fly, there are 19 families, 185 genera and 961 species of biological species, distributed all over the world.

Morphological characteristics

Bat forelimbs are specialized, especially the bones have large changes. The humerus is significantly shorter than the radius (forearm bone), and the ulna is degenerate; Except for the first finger, which is not particularly elongated and has a claw at the end, the rest of the metacarpal bones and phalanges are particularly elongated, and there is a skin membrane between the metacarpal and phalanges, which is connected with the hind limbs and tail backwards.

The epithelial membrane connecting the fingers is called the wing membrane, the mesothelial membrane of the forelimb humerus and hind limbs is called the lateral membrane, the epithelial membrane in front of the humerus and forearm bones of the forelimb is called the anterior wing membrane, and the interfemoral membrane connecting the left and right hind limbs and the tail is called the interfemoral membrane. The interfemoral membrane often has a distance between its membrane margins, which plays the role of supporting the interfemoral membrane, and the lateral epithelium is called the talar membrane. The hindlimbs are short, and the thighs are at right angles to the body and are in the same plane.

The lateral membrane often terminates at the lower tibia, heel, or base of the toe. The hind limbs and feet are completely outside the epithelium, and the five toes have claws for hooking. Bats have light bones all over their bodies.

The skull is highly healed, the bone sutures are not obvious, and many species have nasal recesses (sinuses) with varying degrees of development at the front end of the nasal bone, and often have varying degrees of palatal recesses (palatal sinuses) at the front end of the ventral palatal bone.
