The landform of the Yellowstone Grand Canyon is mainly magmatic rock, with less mud and sand and rocks, and the river water is relatively clear.

The picture taken by Liu Wei jumping into the water seems to open up another world in the audience's vision.

The picture presented by the live dive equipment is clearer than the picture captured by the high-definition camera in the documentary.

"How's it going, brothers, this equipment is good!"

Liu Wei was proud.

Start swimming towards deep water.

The water flow in the deep water is relatively gentle, and the view is more open.

Soon, Liu Wei discovered the American alligator.

Lean your body in the water, head up, swing your tail to swim forward, and twist your limbs to control the direction of swimming.

"Hehe, let me catch it!" Liu Wei smiled.

He didn't rush to catch up, and relied on the flowing water to float forward at a constant speed.

Crocodiles are very sensitive to water ripple fluctuations, and if Liu Wei swims to catch up, he will soon be discovered.

Liu Wei chose to keep his distance first and followed behind the crocodile, carefully observing its physical features, and found a clue.

He was able to determine that it was an adult American alligator.

It is very simple to distinguish the age of the American alligator, one is to look at its body length, the body length in front of you is about two meters and a half or more, which is in the average body length range of an adult American alligator.

Another distinctive feature is the color of its scales, which darkens as the alligator ages, eventually forming the color of black armor from the Cold Weapon era.

When it is born, it has pale yellow stripes evenly distributed on its body, and these stripes gradually fade with age.

In particular, the American alligator, which grows entirely in the wild, has almost no yellow stripes when it reaches adulthood.

However, Liu Wei found that the crocodile swimming in front of him had obvious yellow stripes on its body, and the scales on its body did not reach the level of dark black, but were gray.

The strangest thing is that it has a tail to body length ratio.

The tail of the wild alligator is about half the length of its entire body, and the one in front of me clearly does not reach this ratio.

But it is also inappropriate to question its species identity on this basis, because its snout fully meets the standards of alligators.

The head of the crocodile captured by the camera has the most obvious alligator features, with a shorter and wider snout.

At the same time, the lower teeth fit perfectly into the depression of the upper jaw, and when the mouth is closed, the lower teeth are naturally hidden in the upper jaw.

Other crocodiles generally show their lower teeth.

So there is no doubt about the identity.

However, thinking that this place does not belong to the distribution range of American alligators, Liu Wei has a bold conjecture, perhaps it is a captive-bred crocodile that escaped from the farm and then survived in the wild.

In the United States, tens of thousands of farmed alligators are slaughtered each year, and crocodile skins are made into a variety of expensive leather products.

The leather raw material of many luxury brands in the world is also the crocodile skin of the American alligator. In addition, crocodile meat is rich in protein and has a large consumer market.

In addition to some abnormal physical characteristics, the most important thing to determine if it is a wild or farmed American alligator is to look at its personality, that is, its wild nature.

"Brothers, I'm going to prove my conjecture!" Liu Wei swam up.

The audience still doesn't know what his conjecture is?

As the camera got closer and closer to the crocodile, the audience in the live broadcast room realized that Liu Wei was about to start dying again.

The ripples of the water and the vibration of the sound waves made the crocodile quickly feel that something was approaching.

The crocodile suddenly stopped swimming, swung its tail violently, turned its body one hundred and eighty degrees, its head facing Liu Wei, and a pair of deep eyes looked at Liu Wei.

"it!"

"Scare Lao Tzu!"

"Are you going to fight?"

"This look is so scary!"

"Barrage Protector!"

"Ah Wei, lure it ashore, and if you go ashore, you won't be your opponent!"

Liu Wei said unhurriedly, "Brothers, the American alligator's attack method is fixed: hide itself, and then launch a surprise attack, and if the raid is not successful, it will take the initiative to give up its predatory behavior.

So what we often see is a crocodile hunting prey at the edge of the water, and it's rare to see it rushing up to land to hunt prey.

It is well aware that its hunting skills cannot be fully displayed on land.

My presence has disturbed it, but according to its habits, it may not immediately attack me, at least my distance from it is relatively safe enough for it to have an instinctive self-defense reaction!

So, let's not panic, it's just watching me!"

"Don't panic when you encounter something, take a photo first and post it on Moments!"

"When I saw that mouth, my feet were shaking, and you didn't panic!"

"Ah Wei's mental quality is really strong!"

"What is professionalism? Don't panic!"

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 to be able to adapt to Liu Wei's existence.

It should be said that adaptation to the existence of human beings.

Liu Wei calculated the distance and continued to swim forward.

The expression of the American alligator changed.

Liu Wei has seen many times when a crocodile is about to attack people, but he has not seen it on this crocodile.

As the distance gets closer.

The crocodile suddenly swung its body, turned around again, and quickly slipped away with its wagging tail.

"Ran away?"

"This isn't the beauty I know!"

"Fake crocodile!"

"You coers, are you all looking forward to Ah Wei being bitten?"

Liu Wei smiled: "Brothers, maybe my guess is correct, it is an American alligator who escaped from the farm, and slowly adapted to the wild environment and survived.

The river should be able to provide it with plenty of food, and it settled here.

By observing its reaction, I found that it has less guts, and even if I have already violated its territory, it has not taken the initiative to defend it.

In the wild, this is unlikely to happen to American alligators.

If it's an adult wild beauty short, what you've just seen may be a different picture.

I speculate that this alligator has not even developed the ability to catch small mammals, and lives on the fish and shrimp in the river!"

"I'm going to catch up with it now, stimulate it again, and see how it reacts?"

After speaking, Liu Wei swam up quickly.

Started the race against the American alligator.

There is no doubt about the swimming skills of the American alligator, but Liu Wei's extraordinary body and the assistance provided by the equipment on his body gave him an advantage in this sprint race.

Liu Wei made a bold attempt and directly reached out to grab the crocodile's tail.

The crocodile reacts strongly and flicks its tail sharply.

"Good guy, the strength is still quite strong!" Liu Wei sighed.

The crocodile shook it twice and didn't break free, and immediately bent its upper body to bite Liu Wei.

Liu Wei instantly let go of his hand and floated to the side.

Realizing that this was a difficult opponent, the American alligator dived down, lay on the bottom of the water, opened its huge mouth to face Liu Wei, and made a state of combat readiness.

Liu Wei said: "Although it does not meet the standard of beauty and shortness in my image, but now it seems that this crocodile is still a little temperamental! After all, the genes are still there, and the size is not small!"

Brothers, I'm trying to lure it to the shallows, and I think O'Neill will love it!"
