So Feifei reached out to catch this little frog! But when Feifei was about to catch it, Zhao Zhongyao suddenly grabbed Feifei's hand and said in a stern tone, "Don't touch it."

Feifei was taken aback when he heard what Zhao Zhongyao said, "Dad, what's the matter with you, what a cute little frog, how good is it for us to catch it and raise it home."

Feifei wanted to catch a macaw and be a pet after he came to the Amazon rainforest! But his sister just refused to allow him to do so. In fact, it is certainly not an easy task to catch a macaw. This bird flew in the sky, especially some wild birds, if they saw people, they would have already flown away. It is impossible to get you close to it.

Now that I saw this beautiful little frog, Feifei wanted to take it home as a pet! In fact, not only Feifei fell in love with this little frog, but Tian Tian also feels that this little frog is very beautiful, and she wants to catch one to go home and play with it!

So, without waiting for Zhao Zhongyao to say anything, he said every day: "Dad, my brother is right. We took one home and raised a fun, such a beautiful little frog. Our country does not seem to have such a little frog. Right! Little golden frogs are really rare. If they are kept at home, wouldn’t it make sense! It indicates that our family can also make a fortune!"

Zhao Zhongyao listened to the words of the two children, glared at them and said, "You two should stop thinking about it here. Let me tell you, this is not an ordinary situation. This is called a poison dart frog. Don't look at its golden color. , Looks pretty good. Let me tell you, this poison dart frog secretes a kind of venom, as long as it touches human hands, it can make people poisoned. And this kind of poison is very powerful, within a few minutes, It may cost human lives, you say, can this frog be raised."

When the two children heard what Zhao Zhongyao said, they immediately looked surprised. However, Feifei was still thinking that it would not be his father who was joking with them, but he just didn't want them to catch this little frog home.

So I heard Feifei say: "Dad, are you lying to us and don't want us to catch this little frog. Does this little frog look ordinary! How can it be so poisonous."

Hearing what his brother said every day, he also looked at Zhao Zhongyao and said, "Dad, you are just scaring us! I think this little frog is very ordinary! The skin is very smooth, how can it be so poisonous. The kind of toad in our country It is poisonous, but is there a lot of pimple on its skin! Of course it will secrete toxins. But this little frog has such smooth skin, how can it secrete toxins."

Zhao Zhongyao heard what his daughter said, and said: "This statement of yours is unreasonable. Did you know that some venomous snakes have very bright appearances. The more brightly colored snakes are, the more poisonous they are Snake, I think you know this too! Now let’s see if this little frog is also very bright. What does this show! This shows that this little frog is also poisonous.”

Zhao Zhongyao said that Feifei and Tiantian felt very reasonable. It seems that this little frog may also be a poison frog.

"Dad, to put it this way, this little frog is really poisonous. Otherwise, it won't be such a bright color. Because this golden yellow is unusually eye-catching in this tropical rainforest. If this small If the frog is not poisonous, then it shouldn’t have this bright color. You know, this golden yellow looks unusually eye-catching in the green rain forest, and it really can’t play the role of a protective color. Since this Little frogs have such a striking appearance, that can only show that they are poisonous." After hearing what Zhao Zhongyao said, Feifei felt very reasonable and also said his own opinions.

"Well, I will chase away this little frog first. It is here, which makes me feel a little unsafe." Zhao Zhongyao said as he tapped the little frog with a branch. This little frog disappeared into the bushes not far away with a ‘swish’.

Zhao Zhongyao breathed a sigh of relief now. At this moment, he looked at the two children again and said, "Well, nothing is going on for the time being. I will tell you something about this kind of poison dart frog. understand."

"Okay, let's talk about it!" Feifei and Tiantian now also want to know about this.

At this time, Zhao Zhongyao said: "Poison dart frogs are the most beautiful frogs in the world, and they are also one of the most poisonous species. They are very small, with the smallest being only 1.5 cm, and some species can reach it. 6 cm. Poison dart frogs are mainly distributed in the tropical rain forests of Brazil, Guyana, Colombia and Central America. They have a bright and colorful body, often a combination of black and bright red, yellow, orange, pink, green, and blue. The limbs are covered with scales. Patterns. Among them, lemon yellow is the most dazzling and prominent.

Poison dart frogs are small in size, usually only 1 to 5 cm long, but they are very conspicuous. The color is a combination of black and brilliant red, yellow, orange, pink, green, and blue. Living on or near the ground, all belong to the Poison Frog family, but not all 170 species are poisonous.

Poison dart frogs have some of the strongest toxins. The poison glands scattered throughout the body of this amphibian produce alkaloids that affect the nervous system.

After a series of complicated studies, people learned that this frog poison is a steroidal toxin that can destroy the normal activities of the nervous system. Its main form of action is: when curare is used inside or outside the axon, Both can cause irreversible depolarization of axons, reduce the magnitude of potential action, hinder ion exchange in animals, and make nerve cell membranes a bad conductor of nerve impulses. In this way, the instructions from the nerve center cannot reach tissues and organs normally, and eventually lead to the heart. Stop beating, and there are no effective emergency measures.

However, the venom of poison dart frogs can only work through human blood. If the fingers are not cut, the venom can only cause finger rashes at best, and will not cause death. Clever Indians understand this truth. When they catch poison dart frogs, they always wrap their hands with leaves to avoid poisoning.

After Columbus discovered the New World, "civilized people" broke into the world of poison dart frogs and brought them to the city as pets. The tragic thing is that poison dart frogs are extremely fragile and have strict requirements on the temperature and humidity of food and living environment. Therefore, once they are taken out of the rainforest, it means the end is coming. Poison dart frogs are increasingly threatened by humans!

Sapphire poison dart frogs in the poison dart frog family are very toxic, and their gorgeous body color keeps potential predators far away. Their feet do not have webbed edges and cannot swim in the water, so they will not appear in the aquatic environment. "

After hearing what Zhao Zhongyao said, Feifei and Tiantian felt nervous. They never thought that this kind of poison frog would be so powerful, even if you touch it, it might be poisoned!

When I thought that although this frog has a beautiful appearance, it would be so vicious. Feifei sighed, "Hey, in this world, as long as it is beautiful, it must be very vicious! In the future, we must stay away from these beautiful things."

Feifei said these words accidentally. But Qu Yuqian and her daughter disagreed every day after listening. Of course Qu Yuqian didn't say anything. He just glared at Feifei every day and said, "Brother, what are you talking about! Could it be that a beautiful person must be very vicious!"

When Feifei heard what Tiantian said and knew it was her own, her sister was a little unhappy. So, he quickly explained: "Sister, what are you talking about! I mean animals in nature, but not humans themselves."

Hearing Feifei’s words every day, his elder brother turned white again and smiled: “It’s pretty much the same. You can’t say that my mom and I are both very vicious!”

"Okay, let's move on, everyone! I will go ahead and you must be careful after you follow. We must pay attention to our feet. It is not very far from the Pyramid of the Sun, and there will be no large carnivores. But some small animals, there must be some."

Zhao Zhongyao spoke and walked forward again. He knew that there might be some dangerous little animals on the road ahead, so he still had to be careful.

With the lesson from the last time. When Zhao Zhongyao was walking this time, he was holding a branch in his hand. He used the branch to hit the grass in front of him as he walked. This is called ‘killing the grass to startle the snake’.

Just now, Zhao Zhongyao didn't hold a branch, he was just sharp-eyed, and he saw a small golden thing in the grass in the distance. Then he didn't step on the poison dart frog directly. If you step on this poison dart frog directly, you don't know what serious consequences will be!

Now Zhao Zhongyao is holding a branch in his hand, banging on the weeds in front as he walks. In this way, some small animals will know in advance that someone is coming, and they will quickly escape.

With the help of this branch, Zhao Zhongyao and the others moved much faster. Soon they walked a distance of about five hundred meters. Walk another five hundred meters to reach the destination. But at this moment, a small river appeared in front of him.

It's just that this is a very small river, only four or five meters wide, and the water depth is not deep, maybe about one foot. It is really a small river. In other words, it can't be regarded as a river at all, it can only be regarded as a stream.

The weather is very hot now. When Zhao Zhongyao and the others walked to the edge of the stream, they saw that the water was very clear, and they wanted to wash their faces in the water to cool off.

Feifei was already full of stinky sweat and sweat on his face. He was happy when he saw this stream. I hurried to the stream and wanted to wash my face with some water in my hand to cool down.

But when he just squatted down to wash his face, he saw some small fish swimming from a distance. These little fish are black all over. The mouth is big, and it looks very ordinary. Although Feifei didn't know what these fish were called, she felt that these little fishes were also very common, so she didn't take it seriously.

It's just that Zhao Zhongyao frowned after seeing these little fishes. When he saw that Feifei wanted to hold water to wash his face, he quickly went over and took his arm and said, "Don't wash your face, there is danger in the water."

When Zhao Zhongyao said this, Feifei was taken aback. However, he couldn't figure it out again this time. He also wondered, are there poison dart frogs in the water too! But Zhao Zhongyao said just now that poison dart frogs live on trees, they don't live in water.

"Dad, you have seen something dangerous again. Except for a few small fish, there seems to be nothing dangerous in the water. There are no poisonous dart frogs and no poisonous snakes here. Why are you stopping me again? I’m so hot now, I want to wash my face, what can I do?"

Feifei looked at these little fishes in the water, he couldn't figure it out. After all, he felt there was no danger here. I don't know why Dad is not willing to let him wash his face here.

Tian Tian and Qu Yuqian are the same. They are both women and they like to be clean. Now I have walked hundreds of meters along the rainforest path with weeds, and my face is sweaty. Now I can see that there is a clear stream in front of me. Of course I want to wash my face in the water.

But now seeing Zhao Zhongyao's behavior, the two of them were also stunned. The two came to the water's edge and looked into the water carefully. Apart from seeing a few small fishes, there was really nothing dangerous.

At this time, Zhao Zhongyao pointed to the small black fish in Xiaozhong and said: "Don't underestimate the small fish in the water. This is not an ordinary fish. This is a small fish unique to the stream in the Amazon rainforest. A small fish called piranha is a very fierce fish. If you accidentally jump into such a stream, these small fish will swarm up, and in a moment, you will have your legs The bite was dripping with blood."

When Feifei, Tiantian and Qu Yuqian heard Zhao Zhongyao say this, they all opened their eyes in surprise. After all, they would never have thought that this humble fish would be so powerful.

"Dad, this kind of fish is really so powerful, how can I feel that they won't be so powerful!" Feifei didn't believe it after hearing what Zhao Zhongyao said. After all, this little fish doesn't look very ferocious. Just an ordinary fish.

"Don't let its appearance be fooled. Don't look at its ordinary appearance. But its attack power is absolutely amazing." Zhao Zhongyao looked at the two children and said.

"Dad, can you do an experiment to verify your point of view. How do we feel that this kind of fish is not powerful!" After hearing Zhao Zhongyao's words every day, she was a little unconvinced. After all, she felt that this kind of little fish looked ordinary and nothing special. How can this little fish be so ferocious!

After hearing what his daughter said, Zhao Zhongyao looked around. Then he said: "How to do the experiment. This requires finding a small animal. But how can we catch a small animal!"
