I Have a Safari Park

Liu Xueqing listened to the example of the two people's explanations. Although bats were not mentioned yet, she understood one thing. Killing and driving bats might end in failure. positive effect.

I'm curious, what role do bats play in the ecosystem?

Fang Ye did not directly address this issue.

Before the staff went to drive away the bats, he followed him several times and asked the public why they were afraid of bats.

A very important reason is the poor image of bats!

It is somewhat similar to a mouse, and it has a ferocious face, sharp teeth, and can fly.

Subconsciously associate them with filth, disease.

It is also human nature to use appearance to evaluate the degree of danger of animals.

The fluffy and chubby giant pandas and red pandas don't think they are dangerous, they only think they are cute and cute, while snakes, bats, spiders and other animals that do not meet the public's aesthetics feel very scary, even if they are not dangerous.

So Fang Ye planned to start explaining from the aspect of appearance, so that the audience can understand something, so as to eliminate fear.

"Bats are also an animal with many misunderstandings. In fact, it's not surprising that everyone is afraid of bats. After all, they are ugly and have no human rights."

Fang Ye made a joke, and both the host and Wang Yan laughed.

Wang Yandao: "I have never been afraid of bats. When I was a child, I felt that they were very mysterious. Whenever they came out at dusk, when there was still a little afterglow in the evening, groups of bats appeared out of nowhere and flew around in the sky. .

Like a fairy tale, Cinderella is enchanted, she puts on her crystal slipper, everyone dances together, and at dawn, they all magically disappear again. "

The host said: "I also have a deep impression of bats. When I was a child, I watched "Eternal Dragon Slayer" for a while. The blue-winged bat king Wei smiled and took people away and sucked blood, giving people a creepy feeling, which led to some fear of bats. .

As soon as it got dark, a large number of them came out, flying fast and low, and they dared not go out, for fear that they would suck blood, but my mother told me not to worry, they would not bite. When I grow up, it seems that I rarely see bats. "

Fang Yedao: "Everyone's fear of bats comes from different sources. Many people may be affected by TV dramas, various novels, and film and television works. Vampires have sharp fangs and gloomy faces. Go out to suck human blood.

Ugly is indeed the main reason. In the process of communicating and understanding with the public, a question we are often asked is why this bat looks so ugly and looks disgusting.

His face was wrinkled, layer by layer, he couldn't understand what it was and couldn't accept it.

In fact, the face of a bat looks like this, just like us humans have flexible fingers, giant pandas have black and white fur, and red-crowned cranes have pointed and long mouths, all of which have evolved to better adapt to the external environment. very normal thing.

Let's imagine, if we are standing in front of a bottomless, dark and empty cave, we don't know how deep the cave is, what would we do? "

The host thought for a while and said, "Pick up a stone and throw it down. How long does it take to hear the echo from the stone?"

Fang Ye said: "Yes, we will throw a stone, or stand on the edge and shout down, through the echoes from the darkness, we can know the depth of the cave, and even judge whether the cave is empty or narrow. .Will it be dangerous to fall, is it very straight inside or has all kinds of twists and turns?

This is actually no different from the ability of a bat. "

The host said: "Listen to the sound to identify the position."

Wang Yan smiled and said, "Like those blind heroes, they can still fight back and forth with the enemy by listening to the wind."

Fang Yedao: "When we humans can't judge the location through vision, the use of sound positioning is still engraved in our genes, which is our instinct.

Another example is when we talk face-to-face, which is the normal voice. If we see a friend across the road while shopping, we will instinctively raise our voice and let our voice call his name. If a car comes The car tends to be very noisy, and you may put your hand to your mouth to make a horn and shout loudly.

To call people in this way, we are changing the audio frequency from low frequency to high frequency, which increases the penetration ability, the directivity and directionality will be stronger, and the transmission distance will be longer.

When a bat sees a mosquito or fly in the air, it will also improve its audio frequency, so that it can locate and prey more accurately. So from this perspective, both humans and bats have the same ability. "

Humans and bats have the same abilities?

Many viewers watching the show were stunned when they heard this sentence!

Listening to Fang Ye's dynamic example, I feel that the fog shrouded in the bat is gradually dissipating, and it is not so mysterious anymore!

There is such a wonderful connection, and the fear of them also dissipated a little.

Fang Ye continued: "In the process of evolution, bats need to solve a problem.

Even while flying in the air, if I catch this fly and chew it with my mouth open, I can't continue to shout sound waves with my throat.

Then think about it, is this a very dangerous thing? If you hit a wall, hit a tree and fall into the water, you didn't die because of being hunted, but you hit a wall and killed yourself, this way of death is too useless .

So the bat came up with a very good method, which is to use the nose.

Although bats still use their vocal cords to produce sound waves, they do so with their noses, and the noses form a complex structure that allows for better directional transmission, and correspondingly larger ears to distinguish these sounds and to be able to In the presence of many similar species at the same time, it can distinguish the sound waves emitted by itself. "

Liu Xueqing, who was watching the TV, was stunned for a while: "Oh~ it turns out that this is the reason why bats grow up like this, their noses are wrinkled together!"

Yingying's father also sighed: "So you can't just look at the appearance!"

It's like seeing a person on the street with a mottled face and an extremely ugly face, and you will subconsciously feel fear and fear.

But when I learned that this person was actually trying to save a trapped child in a fire and was burned like this, I would no longer be afraid, but would have a feeling of respect and admiration.

The viewers watching TV have a new understanding of bats at this time.

I feel that bats don't seem so ugly anymore, and my fear has been eliminated a lot, and I am even amazed at the magic of species evolution!

Sending ultrasound through the nose is a really interesting ability.
