It is said that the United States has recently ushered in a wave of cold waves, and many areas have cooled down and snowed, affecting people's work and life, and even NBA stars have been blocked by heavy snow and have no way to play......

It is not only humans who are affected by low temperatures, but in the past two days, a group of crocodiles have also been frozen "out of the circle".
A few days ago, a staff member at Ocean Island Beach Swamp Park in North Carolina, USA, shared a recent situation of a crocodile on Tiktok.
In the video, the usually fierce crocodile lies quietly in the frozen lake.

Only a nose was left outside.

Netizens were attracted by this strange posture and said:
"I'm going to take the opportunity to pinch its nose!"

The tiger's butt can't be touched, the crocodile is frozen, and you can't pinch your nose yet?

Experts say that crocodiles' noses frozen to the ice may seem cold, but that's exactly how they cope with the cold.
Crocodiles are cold-blooded animals and are very susceptible to low temperatures, so when they feel that the temperature drops dramatically and the water surface is about to freeze, they will hide under the water to avoid the cold.
Everyone knows that no matter how cold it is in winter, only the surface of the water will freeze, and there are live fish swimming underwater, and the crocodile also understands this truth, it hides under the water, as if it is wrapped in a quilt of water.
However, crocodiles are not fishes and cannot breathe underwater, so they leave their noses on the surface of the water, and when the surface of the water freezes, they are left with ...... "crocodile nose" on the ice......

Once in a fixed position, the crocodile enters a state known as "brumation", which is somewhat like the hibernation of mammals, but there are some differences.
The crocodile will slow down its heart rate, breathing, and metabolic rate as if it has been pressed the slow button, and its heartbeat can be slowed down to three beats per minute to conserve energy.
In this state, the whole crocodile will show a "dull feeling", just like the second fool in the village, knocking it has to react for a while, "Did someone knock me just now?"

However, crocodiles do not hibernate, they occasionally get up and move, drink saliva, roll over, and then continue to sleep......
This is how crocodiles survive in winter.

In fact, many cold-blooded animals will also use similar methods to survive the winter, when the weather is warm, they will go to a place where there is a sun to heat themselves, and when the weather is cold, they will hide in the mud in the tree hole and pretend to be dead.
In the winter of cold regions, many netizens can pick up some cold-blooded animals that are frozen, they are not dead, they are placed in a warm room, and they can be rejuvenated in a while.

In the wild, these alligators dig a mud pit and hide in the mud pit to keep out the cold, and in the reserve, these crocodiles have no mud to dig up to survive the winter in the water, which is also an example of the environment changing biological habits.

When the weather warms up, these crocodiles will start to slowly move their bodies and break through the ice.

Of course, here is also a reminder that even if the crocodile is frozen into a "crocodile nose", it is still a beast, and it is estimated that it will not mind adding a meal, so friends who want to pinch the "crocodile nose" should not be delusional.
It would be nice to see a professional for you to touch it......
