When it comes to crocodiles, everyone may not know enough, what kind of creature is a crocodile?

The cold-blooded oviparous reptile can describe the crocodile, which is not a fish, perhaps because it can play in the water like a fish, hence the name "crocodile". The crocodile is an animal of the same era as the dinosaurs, the dinosaurs are extinct, but the crocodile is still alive, which shows that it has a tenacious life, now let's learn about this large carnivorous crocodile.

Because the crocodile is an animal of the same era as the dinosaurs, it has a high position in the history of biological evolution. In people's eyes, they are more vividly described as "evil fish", because when it comes to crocodiles, they will immediately think of their bloody mouths, full of sharp teeth, and their whole bodies are covered with hard armor, and they are always ready to hunt with their mouths open, so it is more appropriate to say "evil fish".

Crocodiles love to eat as long as they are meat, in many prairie lake areas, there will always be some crocodiles inhabited in it, they lurk in the water, and when the prairie animals go to the lake to drink, they will be attacked, and most of the animals attacked by them have become a big meal in their mouths.

In the crocodile breeding season, they will sweep out a platform of seven or eight meters with their tails by the river, and there is a nest with a diameter of three meters to place crocodile eggs on the platform, the nest is about four meters away from the river, there are many leaves and shade formation, each nest has about 50 crocodile eggs, the female crocodile will wait by the nest, often sprinkle the nest with water, and maintain the temperature in the nest. Crocodile eggs are hatched using heat, and the sex of the young crocodile is determined by the temperature inside the nest, but the female crocodile balances the sex ratio, so the nest is built in different places.

Because the medicinal value of the whole body of the crocodile is very high, there are many hunters who hunt and resell after hunting, so there are many types of crocodiles that are now endangered, and many species of crocodiles have been listed as protected species. We also need to take action to join the fight to protect crocodiles.

In fact, it is a mammal, and it is also very aggressive, and likes to eat meat very much.

Crocodiles are a dangerous life, especially prone to biting, and are mammals with lungs for breathing.

No. Crocodiles are not fish. Although they have the word "fish" in their name, this is only because they can swim in the water just like fish.

Actually, crocodiles are reptiles in the class of reptiles. Whereas, reptiles and fish are two different animals and have no intersection. Therefore, a crocodile, as a reptile, cannot belong to a fish at the same time.

Specifically, crocodiles are also quite different from fish, with different ways of locomotion, breathing, and reproduction.

Exterior featuresThe crocodile is a higher reptile that breathes with its lungs, its heart is divided into four chambers, it has a bony palate on the roof of its mouth, separating the nasal cavity from the oral cavity, and its teeth are only born in the alveoli of the upper and lower jaws, and these are similar to mammals, which indicates that mammals evolved from reptiles. The crocodile's two eyes grow on the upper end of its head, and in addition to its eyelids, it has a transparent transient membrane, a structure that allows it to adapt to the environment in the water.

Because the crocodile's nostrils are located on the back of the upper end, there are valves inside, so when it dives into the water, the valves automatically close, which can prevent water from flowing into the nostrils, and in its pharynx, there is also a thin and elastic membrane, when this membrane is closed, then its mouth and respiratory tract are separated, so even if it opens its mouth wide in the water, the water will not enter the respiratory tract and lungs. Its long, thick tail is not only the "rudder" when swimming, but also a tool for predation and a ** against enemies.

No, the overlord of the earth, who belongs to the same main dragon as the dinosaurs, is actually considered a fish?

Crocodiles, as a food chain, are considered to be the top animals. When it comes to crocodiles, people will feel fierce and vicious, feel very terrifying, and may think that crocodiles eat people? Or to eat some other animals.

It's terrifying. Injury-type, very dangerous.

But today, I want to give you a science about the natural enemies of crocodiles. You say that the crocodile is so powerful, will it still have natural predators? Of course, no matter what kind of animal it is, it will have a natural predator, and if there is no natural predator, then it will destabilize the ecosystem.

The creature will grow endlessly. However, the biosphere is balanced and stable, so no matter what kind of organism, it will have its corresponding natural enemies to maintain the balance of this ecosystem.

So what kind of creatures can act as natural enemies of crocodiles? There is one of them. Jaguars, for example, often feed on crocodiles.

This "often" is very important, and it is possible that some animals will inadvertently do such things, but only by accident. And it, this creature. They often feed on crocodiles.

Some documentaries on the Internet can be seen often, if you have friends watching the animal world. You will also see some of these clips of jaguars hunting crocodiles. Very exciting!

It's very intense, and it's very shocking.

The crocodile preys on the crocodile, just like any other animal, quietly walking behind its prey and pounces on its back. Then bit his neck. The jaguar's teeth bite very strongly, otherwise how can it be said to be the natural enemy of crocodiles?

A single bite can pierce the skull of a crocodile. The crocodile was immediately paralyzed and unable to resist. This is what doctors often call brain death.

There are two types of death, one is brain death and the other is heart death.

I'm sure everyone knows about this. Other big cats have also preyed on crocodiles, but not as often as the jaguars. It has been recorded that a Bengal tiger in India has preyed on a crocodile, which is very big and incredible.

Therefore, whether it is the animal at the bottom or the animal at the top of the food chain, it will have its corresponding natural enemies to maintain the balance of this ecosystem, and the crocodile. It's no exception.

Jaguar. The jaguar is the archenemy of the crocodile, and there are other large fish that pose a threat to the crocodile as well.

The natural predator of the crocodile is the shark, because the shark swims faster than the crocodile and is able to swallow the crocodile in one bite.

Cougars, rhinoceros, pythons, cougars, hippos, elephants, bull sharks, these are the natural predators of crocodiles.

The crocodile is not a fish, it is an amphibian reptilian.

Crocodiles are not fish, they are reptiles. Reptiles generally crawl close to the ground, have lungs in their bodies, and their bodies are covered with scales or nails.
