The forest zoo has a total of 23 modern animal exhibition halls such as the Birds' Song Forest, the Golden Monkey House, the Waterfowl Hall, the Children's Animal Village, and the Rhino Hall. It also has a liger and tiger dispersing area, a large herbivore dispersing area, and a wolf dispersing area.
There are 5 large-scale scattered areas including 240 species of animals on display. More than 5,000 animals (heads) of more than 240 species are on display. The park area is home to more than 40 species of migratory and resident birds such as pheasants, pigeons, and finches, and 20 species of hares, wolves, and ferrets.
A variety of mammals. The green coverage rate of the park area reaches 95.8%. The main tree species include larch, Korean pine, Scotch pine, yellow pineapple, walnut tree, linden tree, oak tree, poplar tree, white birch and more than 50 species. p>
"Let's go and feed the elephants together."
In the roaming area, many tourists are taking some grass or sugar cane to feed the elephants.
Next to the elephant stands the keeper.
Lin Meiqi ran over and picked up a piece of sugar cane to feed to the elephant.
"Hurry up and take pictures for me."
She posed in a few cute poses and urged.
Lu Ning took a few photos of her, and she snatched the phone away.
And he was looking at the elephant in a daze.
Information about elephants began to appear in my mind.
Elephants have three abilities that are different from other animals.
The first ability: infrasound.
Elephants can not only hear infrasound waves, but also emit infrasound waves. This is unique in the animal kingdom.
Elephants can emit sound waves of about 10hz, which are infrasound waves. Communication between elephants is usually infrasound waves, which cannot be heard by humans.
The hearing frequency range of elephants is 1 Hz------Hertz.
The frequency range of sound that humans can usually hear is 20 Hz to Hz.
Elephants can communicate using infrasound waves that are inaudible to humans, and can generally travel up to 11 kilometers without interference.
The second ability: smell.
The elephant's sense of smell is outstanding among animals, and is more than five times that of dogs. Apart from bears, it has the most sensitive sense of smell in the biological world. Although its sense of smell is not as strong as that of bears, it has the most olfactory genes among all animals.
So its sense of smell is the most reliable.
The third ability: Elephants basically do not suffer from cancer.
Now research has shown that only naked mole rats do not get cancer. But apart from naked mole rats, elephants have the lowest rate of cancer, and only 5% of elephants will die of cancer.
You must know that the bigger the body, the greater the risk of getting cancer, and why is it difficult for elephants to get cancer?
This is about a tumor suppressor gene called tp53.
This gene produces a protein called p53, which is responsible for monitoring the integrity of the gene. If DNA is found to be damaged, it will promote DNA repair. If there is no way to repair it, it will initiate an apoptosis program and induce bacterial 'suicide'.
To prevent these abnormal cells from getting out of control and becoming cancer cells.
The number of copies of the tp53 gene in elephants is 20, while ordinary animals and humans only have one copy of tp53, which is equivalent to 20 copies of insurance on elephants. Therefore, elephants basically do not get cancer.
Moreover, the tp53 gene is not only powerful in suppressing tumors, it is also very efficient in clearing abnormal cells.
The tp53 gene is the natural guardian of the organism.

"What are you doing? Come here and take pictures for me."
"Come on, let's take a photo together, 123 Eggplant~"
Lu Ning was dragged by Lin Meiqi to take pictures. After a while, his mobile phone received a photo of the two together.
Not to mention, it’s pretty good-looking.
"Don't you think it looks pretty?"
"I'm pretty, but you look so stupid."
"Let's go, let's go to the next venue."
Lin Meiqi said hello and ran in first with the team in front.
In front is the area where ligers and tigers roam.
At a glance, there are wild beasts.
By the way, tigers can also emit infrasound waves. The roar of tigers in the mountains is no joke.
Continuing forward, we soon arrived at the aquarium.
People flocked to the aquarium to watch the dolphin show.
When he saw the dolphins, Lu Ning thought of the dolphins' abilities.
The hearing of dolphins is second to none in the biological world. They can hear sounds of 150 Hz-Hz and can also emit sounds of 7000 Hz-Hz. They also have advanced echolocation. They emit sound waves and process the reflected waves, allowing them to identify the front.
Not only the position of the object, but also the size and shape of the object.
It is the natural B-ultrasound in nature.
The principle of vocalization of dolphins is different from that of other mammals. It does not have vocal cords for production. There is a breathing hole on the top of its head with valves inside. When air enters the breathing hole, it can use the valves to adjust the size of the airflow, thereby making different high and low sounds.
The voice comes.
There are two horn-shaped air bags on its front jaw, which can emit sound waves in a direction. The sound waves it emits are not of a single frequency, and the speed can also be changed. When receiving, the jaw receives high-frequency sound waves, and the ears receive low-frequency sound waves.
-------------
After watching the performance, Lin Meiqi went up to take photos with the trainer and the dolphins.
After leaving the dolphinarium, they continued moving forward.
Next is the bird area.
The bird area includes peacocks, ostriches, emus, golden eagles, vultures, vultures, falcons, black swans, white swans, mandarin ducks, pelicans, gray geese, bean geese, bar-headed geese, white-fronted geese, mallards, and shelducks.
, painted-faced duck, turned-nosed shelduck, etc.
These include goshawks and sparrowhawks.
Eagle is the ability that Lu Ning wants to get more. Unfortunately, there are glass and nets to isolate it, making it impossible to contact.
"Why are you always staring at it? Do you still want to go to heaven?"
Lin Meiqi giggled when she saw Lu Ning staring at an eagle in the park.
"Who wouldn't want to go to heaven if they could?"
"We can fly. We didn't fly here just yesterday. You won't forget it, right? Poor child, maybe you have amnesia!"
Lin Meiqi showed an exaggerated expression and looked at him with wide eyes.
Lu Ning gave her a look.
This guy just likes to make jokes like this.
He turned his head and looked at the eagle again. The eagle seemed to be a little lazy because of being imprisoned.
Having no worries about food and clothing, but losing freedom is like how many people do.
You can't have your cake and eat it too.
----------
After seeing so many animals just now, Lu Ning's heart was already a little excited.
He hesitated whether to copy the abilities of elephants or dolphins. One was infrasound and the other was ultrasonic, which was a bit confusing.
He really wanted to send a post to netizens - if it were you, what would you choose?
Well, only children make choices, of course adults want both.
Well, yes, Lu Ning thinks so too.
So when the two of them walked back after visiting the zoo, Lu Ning copied the elephant's ability.
As for the dolphins, we can only talk about it later.
Why copy the elephant first.
The reason is simple, because infrasound waves can be used as a means of attack, while ultrasonic waves are more of an auxiliary.
The assistance has no practical effect for the time being, and Lu Ning is more interested in the attack ability of infrasonic waves.
Sound waves with a frequency less than 20hz (Hertz) are called infrasound waves. Infrasound waves are not easily attenuated and are not easily absorbed by water and air. Infrasound waves often have very long wavelengths, so they can diffract around certain large obstacles. Some infrasound waves can circle the earth 2
to 3 weeks. Because infrasound waves of certain frequencies are close to or even the same as the vibration frequency of human organs, they easily resonate with human organs and are very harmful to the human body. In dangerous cases, they can cause death.
A 7000hz sound wave can be blocked by a piece of paper, while a 7hz infrasound wave can penetrate more than ten meters of reinforced concrete. Infrasound waves generated by earthquakes or nuclear explosions can destroy houses on the shore. If the infrasound resonates with surrounding objects, it can
Emits considerable energy. For example, infrasound of 4hz-8hz can resonate in the human abdominal cavity, causing strong resonance in the heart and damage to the lung wall.
Such powerful infrasound waves have already been studied intensively by major countries.
The application of infrasound waves in the military, for example, can use the strong penetrability of infrasound waves to create infrasonic weapons that can penetrate tanks and armored vehicles. Infrasonic weapons generally only harm people and do not cause environmental pollution.
In 1986, due to technical negligence during an experiment in a certain country, infrasound waves rushed out of the laboratory, resulting in the inexplicable death of 30 residents 16 kilometers away from the laboratory.
Infrasound bombs can instantly kill everyone within a ten-kilometer radius, whether in the air, on the ground, underground, or in the water.
Infrasonic weapons are divided into two categories: neural infrasound weapons and organ-type infrasound weapons.
The infrasound frequency of organ-type infrasound weapons is the same as the natural frequency (4-18hz) of human internal organs, causing strong resonance in human internal organs.
The infrasound frequency of neural infrasound weapons is the same as the alpha rhythm of the human brain (8-12hz), which directly affects the human brain.
Both can cause physical discomfort in mild cases and death in severe cases. Therefore, this infrasonic weapon cannot be protected by covering your ears. Moreover, during the development of infrasonic weapons, it was discovered that once fired, this weapon will not
The damage is divided between the enemy and ourselves, unless our own side takes special protection in advance or is outside the weapon's range.
But it has obvious advantages. It has a long attack range and strong penetrating power. It can directly cause injury or death without causing damage. It has strong maneuverability and can be used by individual soldiers and aircraft.
The great road is invisible, but the great sound is silent.
It’s terrifying to think about a person dying for no reason under an infrasonic attack.
By copying the elephant's ability, Lu Ning will be able to do this kind of attack.
For a time, he was looking forward to it very much.
