Introduction to the role of animal ears, what are the functions of animal ears?

The ears of animals have a variety of functions, which are described below:

1.Most animals' ears help them collect and recognize sounds. Sound is transmitted to the brain through the ear, allowing the animal to hear and respond to sounds in its surroundings.

2.Some animals' ears can be used to sense orientation and positioning. For example, horses and dolphins have large and movable ears that are able to pick up distant sounds and can determine the direction of sounds by turning their ears.

3.The ears of some animals also have the function of regulating body temperature. For example, elephant ears are very large and broad, shaped like fans, which can help dissipate heat, using ear fanning to create air flow and lower body temperature.

4.Some animals' ears have a function to protect themselves. For example, a rabbit's long ears are able to protect itself from being pricked by a branch.

Overall, an animal's ears play an important role in hearing, positioning, regulating body temperature, and protecting themselves.

Animal ears are generally used to listen to sounds, find sound sources, and are also used to repel insects and flies, and are also used to signal and make threats. More primitive animals do not have full ears and rely on the vibrations of air currents to sense sounds.

<>1. Rabbits have long ears and a wide range of sound acceptance, because rabbits are relatively weak in other senses and need hearing to maintain vigilance;

2. The ears of birds are small and almost invisible, which is convenient for flight and reduces drag. However, the ears of birds generally have a wide range of sounds, and can transmit information to each other through sound or behavior;

3. The ears of bats can receive sonar echoes;

4. The dog's ears are erected, and they are more sensitive to sounds, and they can also turn and hear sounds coming from all directions;

5. The ears of the mole do not have pinna, so it is easy to drill around in the hole;

6. The ears of squirrels have the effect of protecting the eyes from being hurt by the thorns of the branches;

7. The elephant's ears are large and thin, and they are full of blood vessels, which can speed up heat dissipation;

8. The horse's ears have two large ear doors, and because of the large pinna, the sound received from the air is also large, and the hearing is very sensitive.

Animal ears are mostly used for hearing. Animals with large ear areas have good hearing. Some animal ears can also repel mosquitoes, such as lions, sheep, horses, etc. Elephant ears dissipate heat, and fish perceive their surroundings by sensing the flow of water through their lateral lines.

The ears of bats, which are used to receive sonar echoes. The dog's ears are pricked up, and it can hear the slightest sound, and it can also turn and hear sounds coming from all directions. On the contrary, pigs have large ears and droop, so they are hearing-dull and sleep-loving.

There are also animals that have ears that only have an external auditory canal and no pinna. For example, moles don't have pinna in their ears, which makes it easier to burrow around in the ground. Birds' ears also have no pinna.

If there are pinna, they increase drag as they fly.

1. Rabbits. The main function of rabbit ears is to regulate body temperature and enhance their hearing range. The long ears can help them hear the sounds of the liquid bridge plexus at a distance, so that they can protect themselves from predators.

2. Pigs. The large area of pig ears is conducive to heat dissipation and is conducive to the pigs to adapt to the stuffy environment in captivity.

3. Cattle. The ear tag on the cow's ear is equivalent to the cow's ID card, recording a lot of information about the cow, such as: maternal history, health information, date of birth, feed intake, family information, milk production, etc., the staff can control the growth and health of the cow through this ear tag.

4. Sheep. Sheep ears are pointed and long, and their shape resembles an oval. The sheep's ears have the function of discerning vibrations, which can convert the sound emitted by vibrations into nerve signals, which are then transmitted to the brain. Giving sheep hearing plays an extremely important role in foraging for food and evading enemies.

5. Chicken. The chicken's ears grow on the lower right side of its head, and its ears can hear sounds far away. However, its ears are quite cleverly raw, with only ear holes and no ear shells.

6. Felines.

Due to the short nose and jaw, the face looks flatter, which makes their ears appear large and eye-catching. The ears gradually decrease from the base to the tree, and the tips of the ears are round or pointed, and they are erect upwards. Felines have keen hearing and can hear many sounds that humans can't.

7. Dogs. The dog's ears are erected, and it can hear the slightest sound, and it can turn around and hear sounds coming from all directions. Dogs can distinguish between very small and high-frequency sounds (ultrasound).

8. Horses. The horse's ears move forward to say that it is interested in something. A horse doesn't just use its head to convey a certain message, but the specific movements of its eyes and ears also convey a certain specific meaning to people.

9. Bats. The ear can receive sonar echoes, which emit sound waves from the mouth that are 20,000 hertz higher, and when they encounter obstacles, they will reflect back and transmit them to the sensitive ears of bats. Bats use their brains to determine whether to eat or flee by judging the appearance of obstacles.

10. Elephants.

The sakura elephant can hear infrasound, and the frequency of infrasound (sound less than 20 Hz) is too low for people to hear. Their large fan-shaped ears collect more information about sound waves in the air, and elephants are able to recognize the low-frequency sounds and calls of their mates.

1. The ears of bats, which are used to receive sonar echoes.

2. The dog's ears are pricked up, as long as there is a sound, it can hear it, and it can also turn around and hear sounds in all directions.

3. Pigs have big, droopy ears, so their hearing is dull, and they like to sleep.

4. The mole's ears do not have pinna, so it is easy for it to burrow in the ground.

5. Birds' ears also have no pinna. If they have ears, they increase their drag when flying.

6. A cat's ears can clearly identify sounds in the range of 3 inches to 3 feet**, determine the exact sound made by objects moving back and forth, and direct their eyes in the same direction.

Dogs have sensitive ears and can hear things five miles away.

The ears of bats can receive ultrasound.

Once the dog's ears are erected, it means that he **.

Elephant, used to fan the wind, cool down. The rest seems to only be used to listen to sounds.

The ears of the chicken keep the body balanced.

The ear converts the sound from the vibrations into nerve signals, which are then transmitted to the brain. In the brain, these signals are translated into understandable words, **, and other sounds.

The ear consists of three parts: the outer ear, the middle ear, and the inner ear. Auditory receptors and positional receptors are located in the inner ear, so the ear is also called auditory cavern. The outer and middle ears are also listed as appendages to hearing bits.

The outer ear consists of two parts: the auricular and the external auditory canal. In addition, there are ear hairs and some glands on the ** of the external auditory canal, and the secretions and ear hairs of the glands have a certain blocking effect on the entry of foreign bodies such as dust from the outside.

Most of the animals use their ears to pretend to be sensitive and listening. Animals with large ear areas have good hearing. Some animal ears can also repel mosquitoes, such as lions, sheep, horses, etc. Elephant ears dissipate heat, and fish perceive their surroundings by sensing the flow of water through their lateral lines.
