Which is more powerful, the piranha, the scavenger or the alligator eel? What happens when you keep them together?

To say that the recent more famous invasive alien species, I am afraid that it is not the crocodile eel, it is famous for the action of draining the lake water in Ruzhou Central Park to catch fish, so that the whole network has realized their harm.

Which is more powerful, the piranha, the scavenger or the alligator eel? What happens when you keep them together?

In addition to alligator eels, there are many fish listed in the list of invasive alien species in the world, such as scavengers, tilapia, piranhas, mosquito-eating fish, etc., most of them because of their strong survivability, fierce temperament or lack of natural enemies and other factors, once a stable population is formed in the wild waters, it will pose a serious threat to native fish.

Crocodile eels are currently mostly found in artificial water bodies on the mainland, with fewer wild waters; Piranhas already have a certain population size in the wild waters of the mainland, and from time to time there are anglers to catch them; Scavengers have flooded some parts of the southern part of the continent, and some provinces even need to be salvaged to control their numbers.

All three species of fish are highly adaptable, lacking predators in continental waters, and once a stable population is formed, it is likely to bring disaster to the mainland's native fish.

So what happens if piranhas, scavengers and alligator eels are kept together? Who will be the winner? Let's talk about this interesting topic.

Before we do that, let's take a look at these three terrible fish species separately.

Which is more powerful, the piranha, the scavenger or the alligator eel? What happens when you keep them together?

1. Piranha

Piranha pomfret commonly known as piranha, it refers not to a fish, but a type of fish, is a variety of carnivorous fish under the sawfish family, as many as 40 species, the most famous of which is the red-bellied sawfish, commonly known as the red-bellied piranha.

Piranha is native to South America and is widely distributed in the freshwater waters of South America. Their necks are short, their skulls are hard, and their mouths are covered with two rows of sharp teeth.

The piranha is about 20 cm long, small in size, and the individual combat ability is not strong. But they tend to come out in groups, ranging from a few dozen to hundreds of collective activities, and once there is a wind and grass, they will come out of the nest.

Piranhas rely mainly on fluctuations in water to lock in their prey, which allows them to launch indiscriminate attacks on aquatic animals. Therefore, even large animals such as humans and cattle that fall into the water will be attacked by piranhas.

Someone once did an experiment in the Amazon River, throwing a cow into a river full of piranhas, and in less than an hour, the cow was left with only a pile of skeletons.

Piranhas first entered the continent as ornamental fish, and some fish lovers love this fierce fish. If you only keep piranhas in fish tanks at home, they will not become invasive alien species, but at best an alien species.

However, some fish farmers have released abandoned piranhas into the wild for various reasons, and these piranhas are more adaptable and have no natural enemies in the mainland waters, so they have survived in natural waters.

Fortunately, the number of piranhas in the current wild waters is not much, and it has not yet begun to flood, and anglers also know the harm of piranhas, and once they are caught, they are usually harmless.

2. Scavengers

I believe that everyone is familiar with the scavenger, because it has been flooded in some provinces in the south of the mainland, and it is often caught by anglers. Scavengerland is also a freshwater water area of South America that overlaps with the habitat of piranhas.

Scavengers don't have the sharp teeth of piranhas, nor are they carnivorous fish. Their body length is about 30 cm, usually not more than 40 cm, so it seems harmless to humans and animals.

But scavengers have a special hobby, which is that they especially like to eat fish eggs. A single scavenger can eat 3,000 to 5,000 fish eggs a day, which can seriously reduce the reproductive survival rate of other fish, resulting in a sharp decline in the number of other fish. This is also the main reason why scavengers are listed as one of the top 100 invasive alien species.

The key problem is that scavengers are particularly capable of surviving. After some netizens fished the scavenger and placed it on the shore for an hour, it seemed to have died, and at this time, the scavenger was poured with water, and miraculously came back to life!

Scavengers are also very fertile, with a single scavenger laying 800 eggs at a time and a very high survival rate, which allows them to quickly form population sizes in the waters.

What's more, the scavengers have no predators in the waters of the mainland, and although they are small, they have a body of armor. Scavengers are teleost fish, most of the body is bone, and the body surface is relatively hard, and there are hard barbs on the back, forming a good defense. This leaves most carnivorous fish with nowhere to go, so there are no natural predators in continental waters.

Scavengers also enter the mainland as ornamental fish, and some merchants advertise that they can remove impurities from fish tanks, and raising them with other ornamental fish can purify water quality.

However, friends who have raised scavengers should know that they only eat the algae on the fish tank, and do not eat the excrement of other fish, and the existence of scavengers will squeeze the living space of other fish.

Therefore, some people do not want to raise scavengers, and some people deal with scavengers by releasing them, so the scavengers come to the wild waters of the mainland, and over time, they form a stable population in the natural waters, and even flood.

3. Crocodile eel

Henan Ruzhou City Central Park pumping fish action, so that crocodile eels for everyone to know, I have to say that the Ruzhou side of the operation of the publicity, played a national science popularization effect, let at least 40 million netizens know the harm of crocodile eels.

The alligator eel is an ancient fish that has existed on Earth for more than 100 million years and is the largest carnivorous fish among the 7 species of garnets in North America. They have a crocodile-like short snout and two rows of dagger-sharp teeth, from which the crocodile gar takes its name.

Recent news reports in a variety of artificial lakes or community pools caught crocodile eel, the body length is about 1 meter. This is very large compared to ordinary fish, but in the alligator eel family, they are only "small fish".

Because the adult individual of the alligator gar can grow to more than 2 meters and weigh more than 250 pounds, it is a giant in freshwater waters. Not only that, but the alligator eel is also covered with hard diamond-shaped scales, and its material is the same as the composition of the hardest bone teeth of human beings, and the Mohs hardness reaches 5, which is harder than ordinary steel.

Alligator eels are the top predators in continental waters, and no aquatic creature can suppress them, so crocodile eels will bring destruction to other fish in the habitat waters. A fish farmer once stocked 200,000 fry in his fish pond, and only a few bluefish and silver carp were caught, as well as a few crocodile eels about 1 meter away.

The process of alligator eels entering the mainland is almost the same as that of the scavenger invasion, which is caused by fish lovers abandoning their breeding and releasing them.

Fortunately, most of the crocodile eels only appear in artificial waters, and have not yet formed a stable population size in wild waters. It is too late to control it at this time, otherwise the flood of alligator eels will bring disaster to the native fish of the mainland.

4. What will be the result of keeping them together?

Piranhas, scavengers and alligator eels are invasive alien fish on the mainland, and their lack of natural predators in continental waters, coupled with their own strong survivability, will seriously squeeze the living space of native fish on the mainland once they flood in the wild.

So, what happens if these three fish are kept together? Who will be the winner of the three strong fish?

As we mentioned earlier, both piranha and scavenger origin are in the South American Amazon, and their habitats inherently overlap, and for the most part they are at peace with each other.

Scavengers are omnivorous fish, and as can be seen from the shape of their mouths, they do not pose a threat to piranhas. And the piranha pomfret was not very interested in the scavenger, because there was so little meat on the scavenger's body.

However, piranhas and scavengers may not have a good time in the water where crocodile eels are present. Alligator eels can swallow all aquatic organisms equivalent to or less than 1/4 of their body length, even shellfish with hard shells.

The body length of the piranha is about 20 cm, the crocodile eel can bite one by one, and although the length of the scavenger can reach up to 40 cm, the smaller scavenger will be suppressed by the crocodile eel. And when the alligator eel grows to more than 2 meters in length, all the scavengers are out of the question.

Would you say that scavengers don't have hard bones? Do you still have barbs on your back, can the alligator eel bite? In fact, crocodile eels do not chew at all when they eat, but swallow their prey in its entirety.

The two rows of teeth of the alligator eel are mainly used to fix the prey, when it bites the prey, it will slowly move its upper and lower jaws to swallow the prey in its entirety, and then rely on digestive juices to digest the prey, and the scavenger cannot block the digestive juice of the alligator eel.

In addition, the scales of the crocodile eel all over the body can be called steel armor, even a group of piranha pomfrets, can not find a breakthrough in the crocodile eel, will not cause any damage to the crocodile eel.

5. Conclusion

Many invasive alien species invade the continent in a very similar path, especially those with some ornamental value, some people buy it through certain channels to raise, and have to abandon it for various reasons.

These breeding enthusiasts or caring people choose to dispose of abandoned animals by releasing them into the wild. These released alien species, if there are no natural enemies in the wild environment of the continent, are likely to form a certain scale and gradually flood, squeezing the living space of the native organisms of the continent and even destroying the balance of the ecological chain.

Finally, we call on everyone to consider whether they will have a negative impact on the ecological environment of the mainland when abandoning some organisms, and release is not necessarily the best choice, nor is it necessarily a good deed.
