2020-01-10 | Broken Science original |

If the running turtle makes you astounded, then the players you see next will make you startled.

Yes, you read that right, the flashing picture in the picture is exactly a running crocodile.

In your eyes, the crocodile is obviously fierce. No matter how powerful the animal is, the life is in danger if you enter the crocodile pool. However, no matter how fierce they are, we can always see them lying on the shore and sunbathing on the shore.I can't move, I don't feel like running.

But in fact, crocodile is a strong runner, faster than most humans.

How fast does the crocodile run?

It is reported that a crocodile that can run fast can reach a speed of 18 kilometers per hour regardless of its size, using trotting, dashing or jumping, and four of them have outstanding results :

Nile Crocodile: 30-35km / h;

American Crocodile: 32km / h;

Saltwater crocodile: 24-29km / h;

African dwarf crocodile: 18km / h;

Can crocodile catch up with humans at this speed?

This is a very interesting question. Generally speaking, such a situation will not occur, but if it is true, then the answer is: it may.

Take a college 100-meter run as an example, the passing grades are: boys 14.9s, girls 17.9s, if the speed of uniform running is: 24km / h and 20km / h.

Let's take a look again. The fastest man Bolt, his speed can reach 45km / h.

Comparing the data, which crocodile do you think you can beat?

Crocodile has three running positions, either like a snake, or a horse, or a rabbit.

People run in one position, but there are three types of crocodiles :

匍匐 Forward: This is an effective way to move forward when in marshes and muddy river banks. It drags its belly while pushing forward with its pedals. This is also the most common posture we use every day.

High Gait: This gait is effective for clearing rocks and branches, and it also requires the most energy, because it needs to lift a huge body off the ground.

Running: Similar to a rabbit jumping, the crocodile kicks the ground with its hind legs at the same time, and then touches the ground with its front legs. It looks like it is jumping. American crocodiles, when encountering a dangerous situation, will use this gait to avoid danger.

Crocodile can run, why don't most people see such a running scene?

First of all, not all crocodiles run;

Past research has shown that only a few crocodiles can run, but a new study adds 5 more players, which also shows that crocodiles run much more often than we think.

Florida scientists installed a camera for this purpose and analyzed the gait and speed of 42 individuals from 15 species of crocodile.

The research team noticed that there are 8 species of crocodile that can run or jump, and for the first time correctly recorded the runs of Filipino crocodile, Cuban crocodile, American crocodile, African alligator and African pygmy crocodile.

After this research, scientists believe that although some crocodiles have lost this ability in evolution, running is still quite common among crocodiles.

Secondly, the running of the crocodile is actually "escape", and it almost only appears at dangerous times, which is rare.

Crocodile does not seem to be suitable for running, and is too lazy to run.

When we think of crocodiles, the first thing we think of is its big belly and sharp teeth, and then look at its appearance, we can easily associate them with slow-moving dinosaurs.

However, when a crocodile encounters a dangerous situation, it will take a run to avoid it.

In spite of this, in real life, crocodiles encounter very few dangerous situations. After all, it is too powerful. In addition, the crocodiles we see everyday are all in the zoo.When it comes to danger, let alone escape.

And most of the time they like to stay in the water. In the water, it is the top predator, and almost no animal is its opponent.

Crocodiles swim faster than they run. They are also excellent divers and can hold their breath underwater for up to an hour! Ordinary crocodiles can swim up to 20 kilometers per hour. Most crocodiles swim faster thanruns fast.

It is worth mentioning that they have poor endurance on land, usually only running 30-40 meters at a time, while in the water, they can swim effortlessly and maintain fast pace for a long time.

There are fewer animals than crocodile, and it likes to stay in the water. The various characteristics cause us to rarely observe their running moments, so it is easy to think that they are slow.

There are some unknown facts about crocodile.

Crocodiles like to eat people?

Any animal with temperature is a food source for crocodiles, including humans, of course.

Crocodiles are not picky eaters, they will eat anything from fish to mammals to birds.

If you are very unlucky and it is the next meal, please rest assured that although you may not run the crocodile, it is impossible for the crocodile to chase its prey.

They usually like to lurk. When the other party is not paying attention, they rush to the prey, and then grab the prey in a sweeping motion. Their mouths are very strong and strong, so it is difficult to escape.

If you don't want to be caught by them, then staying away from hungry crocodiles is your best choice, otherwise you may not even have a chance to escape.

Can a crocodile win an animal race?

Crocodiles cannot run long distances at the highest speed, so they cannot win any animal race.

However, this does not prevent them from becoming top hunters.

Most crocodiles are waiting for their prey in the water. When the guard of the prey relaxes, they will attack.

In the animal kingdom, their acceleration is the fastest and most violent.

Maybe you do n’t see the crocodile this second, but the next second, the crocodile will jump out of the water and grab the prey.

Is the crocodile really sleeping with one eye open?

It is said that crocodiles can sleep with one eye open. This is true.

You will often see them lying in the water with one eye open. They seem to be sleeping, while also looking for prey or watching for threats around them.

The crocodile in this state is unilateral hemisphere sleep, which means that one eye and part of the brain are still "working", watching for potential danger, and the other part is resting, very cool!

Is the tear of the crocodile real?

"Crocodile Tears" is derived from a Western proverb, meaning that crocodiles will leave false tears before they eat people, but in fact it evolved from "false tears."

When a crocodile eats its prey, the crocodile often leaves tears and seems to be sad for the victim. However, the truth is that the tears are just to lubricate the eyes.

A scientific explanation for this phenomenon is that tears are the result of hissing and purring when predators swallow their prey. Their feeding behavior forces air through the sinuses to stimulate the tear glands to produce excessive tears.

Why does the crocodile open his mouth on the river bank as if yawning?

You will often find crocodiles lying with their mouths open in the sun.

It seems strange, but the fact is that they are not yawning, they are cooling down, which is a way to cool down.


Crocodile is an ancient creature more than 200 million years ago. It had been with dinosaurs, and it has evolved, survived and reproduced for tens of millions of years.

Crocodiles are very interesting animals. Almost everyone is afraid, but they will also respect and admire their ability!

It's absolutely unnecessary to study how fast a crocodile can run now, because no matter what crocodile, as long as you encounter it, it is best to avoid it, even if the speed is not fast, it is very dangerous.
