Liu Xueqing listened to the examples explained by the two, although she hadn't talked about bats yet, but she understood one thing, culling and driving away bats might end in failure, and if it was really a lot of action, it might have some bad effects.

I wondered, what role do bats do to the ecosystem?

Fang Ye didn't talk about this issue directly.

Before the staff went to drive away bats, he also followed him a few times, asking why citizens are afraid of bats.

A very important reason is the poor image of bats!

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

Subconsciously associate them with dirty, disease.

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

Fluffy and chubby giant pandas and red pandas will not feel that they are dangerous, they will only feel cute and cute, while snakes, bats, spiders and other animals that do not conform to the public's aesthetics will feel very scary, even if they are not dangerous.

Therefore, Fang Ye planned to start with the aspect of appearance, so that the audience could understand it, so as to eliminate fear.

"Bats are also an animal with a lot of misunderstandings, in fact, it's no wonder 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 Yan said: "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, and at night when there was still a little afterglow in the sky, groups of people appeared out of nowhere and flew around in the sky.

Like in a fairy tale, Cinderella is enchanted, puts on a crystal slipper, dances together, and then when dawn comes, they all magically disappear again. ”

The host said: "I also have a deep impression of bats, when I was a child, I watched "Heaven and Dragon Slayer" for a while, and the blue-winged bat king Wei smiled, abducting people and sucking blood, giving people a creepy feeling, resulting in some fear of bats.

As soon as it gets dark, a large number of them come out, flying fast and low, and they don't dare to go out, for fear that they will suck blood, but my mother told me not to worry, they will not bite. When I grew up, I didn't seem to see bats very often. ”

Fang Ye said: "Everyone's fear of bats comes from different sources, there may be many people who are affected from TV series, various film and television works, vampires have sharp fangs, eerie appearances, and take advantage of the dark wind to go out and suck human blood.

Ugliness is indeed a major reason, and in the process of communicating with the public, one of the questions we are often asked is why this bat is so ugly, and it looks disgusting.

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

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

Imagine what we would do if we were standing in front of a bottomless, dark, empty cave where we didn't know how deep it was. ”

The host thought for a moment and said, "Pick up a stone, throw it down, and how long will it take for the stone to echo?" ”

Fang Ye said: "That's right, we will throw a stone, or stand on the edge and shout down, through the echo from this darkness, we can know the depth of the cave, and even judge whether the cave is empty or narrow." Is it 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 bats. ”

The host said: "Listen to the voice and distinguish the position." ”

Wang Yan said with a smile: "Just like those blind heroes, they can still fight back and forth with the enemy by listening to the palm wind." ”

Fang Ye said: "When we humans can't judge the position through vision, it is still engraved in our genes to use sound positioning, which is an instinct of ours.

If we are shopping and see a friend across the road, we will instinctively raise our voice and let our voice shout his name towards him, and if the traffic is very noisy, we may put our hands on our mouths to make a horn shape and shout loudly.

In this way, we are changing the audio from low frequency to high frequency, increasing the penetration ability, the directivity and directionality will be stronger, and the distance will be longer.

When a bat sees a mosquito or fly in the air, it will also improve its own audio, so that it can locate and complete the predation more accurately. So from that point of view, both humans and bats have the same abilities. ”

Do humans and bats have the same abilities?

Many viewers who watched the show were stunned when they heard this!

Listening to Fang Yedong's examples, I felt that the fog shrouded in the bat gradually dissipated, and it was not so mysterious!

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

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

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

Then let's think about it, this is a very dangerous thing, if you hit a wall, hit a tree and fall into the water, you don't die because of being hunted, you hit the wall and die, this way of death is too bad.

So bats came up with a good way to do it, which is to use their noses.

Although bats still use their vocal cords to emit sound waves, they do so through their noses, and the noses form a complex structure that allows for better directional propagation, and their ears are correspondingly larger so that they can distinguish these sounds and distinguish their own sound waves in the presence of many of their own species. ”

Liu Xueqing, who was watching TV, suddenly said: "Oh~ It turns out that the bat looks like this for this reason, and its nose is wrinkled together!" ”

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

It's like seeing a person on the side of the street, with a mottled and ugly face, and you will subconsciously feel scared and afraid.

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

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

I felt that bats didn't seem to be so ugly anymore, my fear was eliminated a lot, and I was even amazed at the magic of species evolution!

Sending ultrasound waves through the nose is indeed an interesting ability.
