Fish has always been one of the most popular ingredients on the table. However, although many fish taste delicious, they contain potential toxicity. The following introduces the ten most poisonous fish in the world: stone fish, puffer fish, red stingray, yellow-sided eel, lion fish, longnose catfish, eel catfish, eel, etc. These fish can pose serious threats to the human body if consumed improperly, so be careful when purchasing and cooking fish to protect your own health. I hope this introduction can increase everyone's understanding of the most dangerous fish.

1. Stonefish (known as "the most painful sting for humans")

The stonefish, commonly known as the poisonous scorpionfish, ranks first in the list of fish toxicity and is described as the "fatal sting" that gives humans the most severe sting. Although the stonefish has an ordinary appearance and is only about 30 centimeters in length, it is good at hiding on the seabed or in rock crevices, disguising itself as an ordinary stone. If someone unfortunately steps on it, the stonefish will fight back without hesitation, unleashing an attack containing deadly toxins. The 12 to 14 sharp fish bones on the back are as sharp as needles and can easily pierce the soles of shoes and injure the soles of the feet. People are instantly poisoned and suffer severe torture for a long time until their lives are in danger. This fish mainly inhabits China's Paracel Islands, Taiwan and other waters, and is distributed in waters from the Indian Ocean to the central Pacific Ocean.

The meat of puffer fish is extremely delicious. An ancient saying goes: "Once you taste the delicious puffer fish meat, all the people in the world will forget its flavor." However, if it is not handled properly or if it is gluttonous and excessive, it may lead to death. Pufferfish is rich in tetrodotoxin, a neurotoxin that is nearly a thousand times more toxic than potassium cyanide and is one of the most toxic non-protein substances in nature. Its content of one part per 50 million is enough to paralyze the nervous system in just 30 minutes, and the minimum lethal dose in the human body is only 0.5 mg. In Japan, people die every year from accidentally ingesting tetrodotoxin. I hope people will take this as a warning to avoid tragic accidents.

The tails of various red rays are equipped with one or more sharp and serrated venomous spines.

The spines on the back of its tail are long and hard enough to penetrate armor. There are venom glands at the base that contain highly toxic liquid. Once stung by a red stingray, the venom will be injected into the victim's body. In mild cases, the victim may suffer severe pain, and in severe cases, may even die.
