Lorsque vous êtes assis sur une belle plage avec vue sur les vagues bleues et ondulantes de l'océan, il est facile d'oublier vos soucis et vos soucis. Cependant, si vous commencez à considérer ce qui se trouve dans les profondeurs profondes et sombres de cette mer, vous ne serez peut-être pas heureux d'apprendre ce qui se cache en dessous. 

L'océan contient certaines des créatures les plus dangereuses, mortelles et inconnues du monde. Notre liste des poissons les plus toxiques et venimeux au monde pourrait vous faire douter de ces vacances à la plage. 

Le top 10 des poissons les plus toxiques et venimeux

Below, you’ll find some of the most frightening fish who have uniquely deadly ways of taking the life of their prey – along with yours. From a jellyfish that can kill you with one zap to a poisson camouflé that can cause cardiac arrest, this list is not one you want to ignore. 

1. Cubozoaires

Top 10 Most Poisonous and Venomous Fish in the World: Cubozoa

Le Cubozoa est plus connu sous le nom de méduse-boîte. Cette belle créature à l'apparence délicate est tout sauf si l'on considère à quel point elle est mortelle. Un animal raisonnablement grand, la méduse-boîte peut peser près de cinq livres et ses nombreux tentacules délicats peuvent mesurer jusqu'à environ dix pieds. 

Bien que d'apparence presque élégante, l'invertébré en forme de boîte est considéré comme l'un des animaux les plus toxiques au monde. D'une seule piqûre, il peut transférer un venin puissant qui étourdit ou tue instantanément sa proie. 

Une piqûre contient des toxines mortelles qui attaquent directement le cœur, le système nerveux et les cellules de la peau. Bien que cette piqûre soit le plus souvent utilisée par la méduse pour attaquer sa proie pour se nourrir, une piqûre pour un humain peut être mortelle. 

Le venin est si puissant et douloureux que la plupart des victimes humaines ne peuvent pas atteindre le rivage avant de mourir. Ils sont susceptibles d'être en état de choc et de se noyer ou de mourir d'une insuffisance cardiaque. 

It’s possible for a person to survive a Cubozoa sting; however, one can expect a nasty scar to go along with weeks of intensive pain. The venomous jellyfish causes as many as 40 deaths per year in the Philippines. 

2. Poisson-globe

Top 10 Most Poisonous and Venomous Fish in the World: Pufferfish

Pufferfish are distinctive sea creatures known for their ability to puff up their body, expanding an array of 360-degree quills to scare off their enemies. But did you know that these venomous fish can be quite deadly? 

The pufferfish contains a dangerous toxin called tetrodotoxin. It runs throughout the animal’s entire body and is derived from bacteria. This toxin is up to 1,200 times more poisonous than cyanide, and one fish has the potential to kill 30 adult humans – with no antidote. 

Pufferfish poison can cause symptoms such as vomiting, difficulty breathing, muscle weakness, and numbness, and it can be lethal if not treated right away.

Cela étant dit, la viande de cet être extraordinaire est en fait considérée comme un mets délicat. C'est vrai - ce poisson super toxique mortel pour les humains sert également de repas que les gens apprécient, en particulier au Japon. 

Not only is this meal costly, but it takes a highly trained, licensed chef to prepare it. That’s because it must be prepared in a specialized way to ensure all the toxins are removed. 

However, in many other countries, it is illegal to serve pufferfish due to the risk of poisoning.

Although there are trained individuals who are experts in the topic, there are still several deaths that occur from eating this venomous fish annually. Only a real daredevil would give this meal a shot. 

3. Poisson chirurgien zèbre

Top 10 Most Poisonous and Venomous Fish in the World: Zebra Surgeon Fish

Arborant des rayures qui rivalisent avec celles du mammifère que nous connaissons et aimons tous, le zèbre, ce poisson accrocheur n'est pas aussi innocent qu'il n'y paraît. Vous ne le remarquerez peut-être pas de loin, mais la créature marine possède une colonne vertébrale érectile aussi tranchante qu'un scalpel. 

The spine sits at the base of the caudal fin and contains powerful, dangerous venom. It cuts into any prey who dares to get too close. In fact, this venomous fish is known to be overly aggressive and will attack any animal or person who comes its way. 

Despite the deadly knife-like fin, the Zebra Surgeon Fish is actually edible. Many enjoy the venomous fish, but there’s still some risk to consuming it. It’s been known to cause a special kind of food poisoning called ciguatera. Ciguatera causes face numbness, itching, and in severe cases, hypotension and a slowing of the heart rate. 

4. Crown of Thorns Starfish

Top 10 Most Poisonous and Venomous Fish in the World: Crown of Thorns Fish

The crown of thorns fish is actually a starfish, and it’s the only starfish in the whole world that is poisonous. Appropriately named, this spikey animal is covered with prickly spines. These sharp needle-like attachments can grow to be as long as two inches, and the venomous fish itself can have anywhere from 7 to 23 arms. 

Une belle contribution aux récifs coralliens, le poisson couronne d'épines se décline dans une grande variété de couleurs. Vous pourriez voir un brun moyen ou des couleurs plus vives comme le vert et le violet avec des épines rouges, jaunes ou bleues. 

Bien qu'elles ne soient pas nécessairement mortelles, les épines de cette étoile de mer peuvent avoir un impact sur la santé humaine. Si vous vous faites piquer par l'un d'eux, vous pourriez ressentir de la douleur, des nausées et des vomissements. La rougeur et l'enflure au site de la blessure sont également courantes. 

5. Raie

Top 10 Most Poisonous and Venomous Fish in the World: Stingray

Pour la plupart, les raies pastenagues sont considérées comme des animaux calmes et dociles. Ils n'ont pas la réputation de rechercher activement les humains dans l'intention de leur faire du mal. 

Cependant, ils ont une forte réaction en termes de défense, et cette attaque peut être mortelle. 

Vous vous souvenez peut-être de Crocodile Hunter Steve Irwin. Ce gardien de zoo australien obsédé par les animaux a manipulé certains des animaux les plus dangereux au monde, jusqu'à ce qu'il soit mortellement attaqué par une raie dans un horrible accident. 

La plupart des blessures aux raies surviennent sous le genou chez les personnes qui se trouvaient au mauvais endroit au mauvais moment. Dans la plupart des cas, la mort est extrêmement rare. Même si une raie contient du venin, elle n'est généralement pas mortelle. 

Mais si une raie vous frappe à la poitrine ou à l'abdomen avec sa queue pointue, elle pourrait vous tuer. Un coup directement au cœur serait très certainement fatal. Tout autre type de piercing peut provoquer de fortes contractions musculaires, très douloureuses. Il peut également provoquer la mort de tissus ou de cellules. 

6. Poisson-coffre

Top 10 Most Poisonous and Venomous Fish in the World Boxfish

Given the close relation of the boxfish to the pufferfish, it shouldn’t come as a surprise that this square-looking fish is also poisonous. Don’t jump to conclusions here – this fish is not nearly as poisonous as the pufferfish. But, it’s still best to keep your distance.

La forme étrange et l'apparence à la mode du poisson-coffre lui donnent un aspect inoffensif. Sa couleur jaune vif est certainement accrocheuse, et elle arbore d'adorables pois noirs partout. 

However, this fish has been known to excrete a dangerous toxin whenever it feels threatened or scared. Their skin cells release this toxin into the water, which will poison anything in the surrounding area. 

La toxine peut décomposer et détruire les globules rouges, ce qui peut être nocif à la fois pour la vie marine et pour les humains qui s'en approchent trop.   

7. Candiru

Le Candiru est un poisson originaire de la région de la rivière Amazon. Il est étrange dans sa ressemblance avec une anguille, car il a une apparence translucide et n'a pas d'écailles comme les autres poissons. 

Ce petit poisson ne mesure qu'environ un pouce de long, il est donc difficile de le voir même dans l'eau. Ce poisson ne possède aucun poison, mais il est assez mortel. C'est un poisson-chat parasite qui aime s'accrocher aux cavités branchiales d'autres poissons, se nourrissant de leur sang. 

Lorsque le Candiru décide de faire d'un humain sa proie, il pénètre en fait dans le corps par l'urètre d'une personne. Une fois à l'intérieur, il lâche ses courtes épines qui l'attachent à la victime et provoquent une inflammation. Il peut également provoquer des hémorragies et éventuellement même la mort.  

8. Poisson-lion

Top 10 Most Poisonous and Venomous Fish in the World: Lionfish

Le poisson-lion est celui qui est assez impressionnant en termes d'apparence. Entièrement recouvert de bandes brunes et blanches, le poisson possède de grandes nageoires gonflées qui coulent gracieusement dans l'eau. 

Bien que ses nageoires soient agréables à regarder, nous vous déconseillons de vous approcher de ce gros félin de l'océan. Animal hautement toxique, la rascasse volante a du venin dans ses épines dorsales. 

The dorsal spines can inject a toxic substance when the fish is touched or grabbed. The venom can cause severe pain and swelling, and it can be life-threatening in some cases.

Heureusement, le poisson n'est pas connu pour être agressif. En fait, c'est en fait un poisson plutôt timide qui aime s'occuper de ses propres affaires. Les épines dorsales agissent simplement comme un mécanisme de défense pour le protéger lorsque les prédateurs se rapprochent trop. 

Il est préférable de rester loin de ces gars-là - le contact avec cette nageoire dorsale entraîne un poison puissant qui peut provoquer des douleurs intenses, des vomissements, un essoufflement et éventuellement une paralysie de tous les muscles du corps humain. Une fois que le muscle cardiaque est touché, le résultat est la mort. 

9. Poisson-pierre

Top 10 Most Poisonous and Venomous Fish in the World Stonefish
Top 10 Most Poisonous and Venomous Fish in the World Stonefish

The stonefish is not a particularly attractive fish, but don’t say that to its face. Hidden in the Red Sea and the Indo-Pacific, this fish houses 13 dorsal spines that are very much venomous. 

The venomous fish can be challenging to spot, as it likes to hide on the seabed. It accomplishes excellent camouflage by burying itself in the sand or hiding within the rocks. When all is said and done, it merely looks like another stone in the ocean.

A sting from one of these many spines can cause a person to lose consciousness. That alone is a threat when you’re in the water. Plus, the venom can also cause cardiac arrest.

The venom can cause severe pain, swelling, and sometimes result in death. Stonefish are usually found in shallow waters near coral reefs, and they are well-camouflaged. When you look at the picture above, keep in mind how close it was taken, and that you wouldn’t see the details that make you recognize the living fish from some distance with your snorkeling mask on.

The very well-made camouflage makes the venomous fish extremely difficult to spot. Stonefish are not aggressive and do not typically attack humans. However, accidents can happen when people step on them or touch them accidentally while swimming or diving.

10. Vipère

Top 10 Most Poisonous and Venomous Fish in the World: Viperfish

Many people fear the deepest depths of the ocean because it’s pitch black and relatively unknown. However, some fear this region of the world because of what we do know – like the venomous viperfish. 

Le poisson des profondeurs a une apparence désagréable, pleine de dents noueuses et dentelées qui atteignent à la fois l'intérieur et l'extérieur de sa bouche. 

Its appearance alone is enough to scare anyone who encounters this fish, but it’s also one of the most venomous fish you can find in the ocean. 

The viperfish is most well known for its light-producing organ, which hangs from a line over its head. The light serves to attract other fish. The viperfish lies completely still as its prey approaches the light, and then it strikes. 

While extraordinarily poisonous and deadly, this venomous fish lives far deeper than you will probably ever go in the ocean. Plus, it’s really only interested in its next meal, not humans. 

Bonus: 11. Cone Snail

Top 10 Most Poisonous and Venomous Fish in the World: Cone Snail

La cone snail is not a fish, but it completes this list nevertheless nicely. The marine snail that is found in tropical and subtropical waters around the world and can be found in many colors. It has a venomous harpoon-like tooth that it uses to capture its prey. The venom of some species of cone snail is very toxic and can cause serious injury or death if not treated instantly.

Luckily, cone snails are not aggressive. The venomous snails do not attack humans on purpose, but accidents can happen when people step on them accidentally.

Do you know the difference between venomous and poisonous fish?

Venomous and poisonous are often used interchangeably, but they actually refer to different ways that animals can harm humans.

A venomous animal has a special organ or gland that produces a toxic substance, which it then injects into its prey or attacker using a bite, sting, or other means of delivery. The venom works by disrupting the normal function of the body’s cells and tissues, and it can cause a range of symptoms, from mild pain and swelling to serious illness or death.

So in short, a venomous fish bites you!

On the other hand, a poisonous animal or plant contains toxins that are harmful when they are ingested or come into contact with the skin. The poison works by being absorbed into the body and causing harm when it reaches certain organs or systems. Poisonous animals and plants do not have a special delivery system for their toxins and do not actively inject them into other organisms.

So in short, a poisonous fish is eaten by you!

To sum up, venomous animals use a delivery system to inject toxins into their prey or attackers, while poisonous animals or plants contain toxins that are harmful when ingested or come into contact with the skin.

Everything else you need to know about venomous and poisonous fish!

Which is the most venomous fish?

The most venomous fish is the poisson-pierre. It is found in the waters of the Pacific and Indian Oceans, and it has venomous spines on its back that can inject a toxic substance when the fish is stepped on or touched.

Stonefish venom is very toxic and can cause serious injury or death if not treated right away.

What are the top 10 most poisonous fish?

Some examples of poisonous fish include the pufferfish, the red lionfish, and the cone snail.

La poisson-globe, also known as fugu, is a type of fish that is highly poisonous due to a toxin called tetrodotoxin that is found in its skin, muscles, and internal organs.

The red lionfish is a species of fish that is native to the Indo-Pacific region, but it has been introduced to the waters of the Caribbean and the western Atlantic Ocean. It has venomous spines on its back and fins that can inject a toxic substance when the fish is touched or grabbed.

La cone snail is a type of marine snail that is found in tropical and subtropical waters around the world. It has a venomous harpoon-like tooth that it uses to capture its prey. The venom of some species of cone snail is very toxic and can cause serious harm or even death if not treated right away. Cone snails are not aggressive and do not usually assault humans, but accidents can happen. When people touch them or step on them accidentally, treatment is required immediately.

What fish have venom?

Many sorts of fish have venom, which they use for either defense or to capture prey. Venom is a toxic substance that is produced by an animal and delivered to its prey or attacker using a bite, sting, or other means of injection. Venom works by disrupting the normal function of the body’s cells and tissues, and it can cause a range of symptoms. The effects range from mild pain and swelling to serious illness or death. Some examples of venomous fish include poisson-pierre, stingrays, weeverfish, and lionfish.

Which fish Cannot be eaten?

There are several types of fish that cannot be eaten due to the toxins they contain. Eating these fish can cause serious illness or death. Some examples of poisonous fish that should not be eaten include the poisson-globe, the lionfish, and the poisson-pierre.

What freshwater fish are venomous?

There are a few species of freshwater fish that are venomous, such as the stingray and the weeverfish. These fish are found in rivers, streams, and lakes in tropical and subtropical regions.

Which fish can be lethally poisonous?

Some fish can be lethally poisonous if you eat them, as they contain toxins that are harmful to humans. These toxins can cause serious illness or death if not treated by a doctor right away. Some examples of fish that can be lethally poisonous include the poisson-globe et le cone snail.

What fish can paralyze you?

There are several types of fish that can produce toxins that can cause paralysis in humans. These toxins work by disrupting the normal function of the body’s muscles and nerves, leading to muscle weakness and difficulty moving. Some examples of fish that can paralyze humans include the poisson-globe et le poisson-pierre.

Can you survive pufferfish poison?

It is possible to survive pufferfish poisoning, but it can be very serious and requires prompt medical treatment. Pufferfish poison can cause symptoms such as vomiting, difficulty breathing, muscle weakness, and numbness. If left untreated, it can lead to coma or death. The severity of the symptoms and the risk of death depend on the amount of poison that was eaten. You should seek professional aid right away to increase the chances to survive pufferfish poison, after ingestion.

Can you eat a blowfish?

Blowfish, also known as pufferfish or fugu, is a type of fish that is poisonous if not prepared properly. In some countries, it is considered a delicacy and is prepared by specially trained chefs who know how to remove the toxic parts of the fish. In other countries, it is illegal to serve blowfish due to the risk of poisoning.

It is generally not safe to eat blowfish unless it has been prepared by a trained professional. Blowfish contains a toxin called tétrodotoxine that is found in its skin, muscles, and internal organs. This toxin is extremely poisonous and can cause symptoms such as vomiting, difficulty breathing, muscle weakness, and numbness, and it can be lethal if not treated shortly.

Only certain parts of the blowfish are safe to eat, and these must be carefully removed by a trained chef to avoid poisoning. Thus, eating blowfish is risky, as it is difficult to know how much toxin is still present in the ready prepared fish dish.

Venomous and poisonous fish: Conclusion

Whether from a sting directly to the heart of an innocent meal in a foreign country, any one of these extremely poisonous and venomous creatures could be the last thing you encounter alive. We can certainly still enjoy the beauty, mystery, and intrigue of the ocean – but sometimes it’s best done from afar.
