Chapter 643: difference

The landforms of the Yellowstone Grand Canyon are mainly dominated by magmatic rocks, with less mud and sand and clearer river water.
Liu Wei jumped into the water to shoot the picture, in the audience's vision, as if opening another world.
The picture presented by the live diving equipment is clearer than the picture taken by the high-definition camera in the documentary.
"How? Brothers, this device is good!"
Liu Weiyang was proud.
Start swimming in deep water.
The water flow in the deep water area is relatively smooth, and the view is more open.
Soon, Liu Wei discovered the American alligator.
Tilt your body in the water, head up, swing your tail to swim forward, twist your limbs to control the direction of swimming.
"Hey, let me catch it!" Liu Wei smiled.
He did not catch up in a hurry, relying on the flowing water to move forward at a constant speed.
The crocodile is very sensitive to the fluctuation of water marks. If Liu Wei swims to catch up, he will be found soon.
Liu Wei chose to keep a distance and trailed behind the crocodile, carefully observed its physical characteristics, and found a clue.
He was able to determine that this was an adult American alligator.
It is very simple to distinguish the age of American alligator. One is to look at its body length. The body length in front of it is more than two and five meters, which is within the average body length of adult American alligator.
Another notable feature is the color of its scales. With age, the skin of the American alligator will become darker and darker, eventually forming a color of black armor during the cold weapon era.
At the time of its birth, the body was evenly distributed with light yellow stripes, which gradually faded with age.
Especially the American alligator, which grows completely in the wild, the yellow stripes are almost hard to see as adults.
However, Liu Wei found that the crocodile swimming in front of him had yellow stripes on his body, and the scales on his body did not reach the level of deep black, grayish.
The weirdest thing is the ratio of its tail to its body length.
The tail of the wild American alligator is roughly half the length of the entire body, and the one in front of it obviously does not reach this proportion.
However, it is also inappropriate to question its species identity because its snout end fully meets the alligator standard.
The head of the crocodile photographed by the camera has the most obvious alligator characteristics, with a shorter and wider snout.
At the same time, the lower teeth and the depression of the upper jaw fit perfectly. When the mouth is closed, the lower teeth are naturally hidden in the upper jaw.
Other crocodiles generally show their lower teeth.
So identity is beyond doubt.
However, thinking that it does not belong to the distribution of American alligators, Liu Wei had a bold conjecture. Perhaps it was a captive crocodile that escaped from the farm and survived in the wild.
In the United States, tens of thousands of farmed American alligators are slaughtered every year, and crocodile skin is made into various expensive leather products.
The leather material of many luxury brands in the world is also the crocodile skin of American alligator. In addition, crocodile meat is rich in protein and has a large consumer market.
In addition to some abnormal physical characteristics, want to determine whether it is wild or farmed American alligator? The most important thing depends on its character, which is wildness.
"Brothers, I'm going to prove my guess!" Liu Wei swam up.
The audience does not yet know what his guess is?
As the camera picture got closer and closer to the crocodile, the audience in the live broadcast realized that Liu Wei was about to die again.
The fluctuation of the water lines and the vibration of the sound waves quickly made the crocodile feel that something was approaching.
The crocodile suddenly stopped swimming, swaying his tail violently, his body turned 180 degrees, his head facing Liu Wei, and a pair of deep eyes staring at Liu Wei.
"Lying trough!"
"Frighten the old man!"
"Are you going to do it?"
"This look is scary!"
"Barrage Guard!"
"Awei, lure it ashore, and it will not be your opponent when you land!"
Liu Wei said unhurriedly, "Brothers, the American Alligator's attacking method is fixed: hide itself and then launch a raid. If the raid is unsuccessful, it will voluntarily give up its predatory behavior.
Therefore, we often see scenes where crocodiles prey on the edge of the water, and rarely see it rushing to the land to prey.
It is very clear that its hunting skills cannot be fully exerted on land.
My appearance disturbed it, but according to its habits, it may not immediately attack me, at least my distance from it is still relatively safe, not enough to make it instinctive self-defense reaction!
So don’t panic, it’s just watching me!"
"Don't panic when things happen, take a picture first and post a circle of friends!"
"Why didn't I see that mouth, my feet were shaking, you don't panic!"
"A Wei's compelling mental quality is really strong!"
"What is professional? Don't panic when something happens!"
The crocodile stared at Liu Wei for a moment, did not rush towards Liu Wei, nor did he make a symbolic attack to scare Liu Wei.
It seems that it can adapt to Liu Wei's existence.
It should be said that adapting to the existence of humanity.
Liu Wei calculated the distance and continued to swim forward.
The look of the American alligator has changed.
Liu Wei has seen the look of a crocodile attacking people many times, but he has not seen it on this crocodile.
As the distance gets closer.
The crocodile suddenly swayed his body and turned again, and the swaying tail quickly slipped away.
"Ran?"
"This is not the beauty short I know!"
"Fake crocodile!"
"You guys, are you looking forward to Awei being bitten?"
Liu Wei smiled: "Brothers, maybe my guess is correct. It is an American alligator that escaped from the farm and slowly adapted to the wild environment and survived.
The river water should be able to provide it with enough food, it settled here.
By observing its reaction, I found that its guts are relatively small. Even though I have violated its territory, it has not taken the initiative to attack to guard the territory.
In the wild, this situation cannot happen to American alligators.
If it is an adult wild beauty short, you may have just seen another picture.
I speculate that this alligator has not yet exercised its ability to catch small mammals, and lives on the fish and shrimp in the river!"
"I'm catching up now and stimulating it again to see how it reacts?"
After finishing, Liu Wei swam up quickly.
Started the race against the American Alligator.
The swimming skills of the American Alligator are unquestionable, but Liu Wei’s extraordinary body and the assistance provided by his equipment have given him an advantage in this race.
Liu Wei made a bold attempt and reached out to grab the crocodile's tail.
The crocodile responded strongly and flicked its tail.
"Good guy, the strength is quite strong!" Liu Wei sighed.
The crocodile flicked twice without breaking away, and immediately bent his upper body to bite at Liu Wei.
Liu Wei instantly disengaged and drifted aside.
The American Alligator realized that this was a difficult opponent. He dived down and lay on the bottom of the water. He opened his mouth to face Liu Wei and made a state of combat readiness.
Liu Weidao said: "Although I didn't meet the standard of shorting the Chinese and American shorts in my image, it seems that this crocodile is still a little tempered! After all, the genes are still there and they are not small!
Brothers, I tried to lure it to the shoal, I think O'Neill would love it! "
