There are more than fifty species of poisonous fish in various parts of the world, and every year many people develop severe symptoms of poisoning and even death due to exposure to the toxins secreted by these fish. Toxins are a self-defense weapon for these fish and can help them resist larger enemies such as large flounders and rainbows and rays. Symptoms of human poisoning from fish poisoning include paralysis, paralysis, dyspnea, uncontrollable massive bleeding, and blood poisoning.
If you see elegant cartilaginous animals with tail pins on their swims, be sure to control your hands and never tease them, these stingrays are highly poisonous.

Stingrays have killed many people, the most famous of which is "Mr. Crocodile" Steve Irwin (1962-2006).
He was a respected zoologist who, while filming Animal Planet: The Deadliest Marine Animals, was too close to a stingray in 2006, but at the time the stingray, like other of its kind, was lying on the surface of the sand, hiding itself so well that Alvin failed to notice it and was stabbed to death.
At that time, many of Alvin's fans were emotional, and they killed a large number of stingrays to vent their dissatisfaction, and regarded stingrays as vicious fish. However, in fact, the incident is not as simple as people think, and from the official report, it can be seen that Alvin's death was not an accident.
The report said That at the time, Alvin and his colleagues were filming, And Alvin swam past the stingray, and then the tank fish assumed a defensive posture, but Alvin ignored the stingray warning and remained close to the stingray. Perhaps the poor fish had no choice but to attack Alvin after several warnings were ineffective. Stingray's barbed spines penetrated Alvin's chest and stabbed into his heart.
Approaching, Alvin did another stupid thing when Alvin pulled out the thorn out of reflex, which caused more severe trauma and eventually led to death. Various media claim that such a "bizarre accident" is very rare, and the details of the incident are unknown, but the stingray is actually not as vicious and terrible as people think, Alvin's part is more special, and he used the wrong way of pulling a needle to save himself, which is the two main causes of his death.

There are more than a hundred species of stingrays, six families in total, and they are distributed in shallow waters along the coasts of the world. Some species of stingray are very large, with pectoral fins opening up to 3 meters wide and weighing more than 300 kg. They usually lie on the sand on the seabed or glide at a slow pace, hunting for shellfish and fish, and then crushing their prey with rows of pure teeth.
When they are in danger, the stingers on their tails come in handy. Stingray has two grooves on the bottom surface of the stinger, the white tissue in the groove is the gland that makes venom, the length of different species of stingers is also different, the stingers of European stingers are about 12 cm long, and the stinger stingers that inhabit tropical seas are longer, reaching more than 40 cm. Stingers are bone tissue at the base of the tail, shaped like a bayonet, and incredibly hard.
The average stingray has only one stinger, but some species have two, base to three stingers. Their whip-like tails are not helpful at all when swimming, but they can be used as an excellent attack weapon.
When threatened, stingrays will use their tails back and forth, and the base will be thrown directly forward over the head, stabbing the enemy with a stinger. In addition to the terrible venom, the jagged edges of the stinger leave jagged wounds on enemies, enhancing the power of their attacks. This fish toxin works extremely quickly in the human body, causing pain and swelling quickly, affecting the nervous system, causing abnormal breathing and heartbeat, and in severe cases, even death.
Stingray is an ancient fish, they are docile, generally do not actively attack humans, the vast majority of stinging swimmers are because the swimmer disturbed the stingray. These critters are not yet accustomed to the waters that tourists pay attention to, and tourists are better off not getting too close to them.
Alert tank fish take a defensive posture, arching their tails, exposing jagged stingers with barbs. If you accidentally step on the stingray, it must be a very painful experience, so it is best to drag your feet when walking in shallow waters where stingrays are often infested.
This approach is also required for walking in many freshwater areas of the tropics. The District of Columbia, Missouri, is one of the most severe stings from stings, and reports from Colombian health authorities indicate that more than 2,000 people are stabbed each year by stingings by stingers. There are at least 3 toxins on the spines of blue-spotted fish, two of which cause necrosis of the body and one of which is serotonin, which causes pain, which is the same toxin found in jellyfish venom.
The relative lethality of stingrays when defending themselves is related to the body parts of stings punctured by stinger spines. If the area of the stab is an ankle, calf or hand, the injured person will suffer severe pain caused by the trauma, and the other serotonin will also increase the pain, such a stab wound if treated by Yidang, the wound will eventually heal, leaving only scars and a story of people and stingrays.
Even without any treatment, it will heal over time, and the toxicity of stingray venom will eventually slowly decrease, but it is very easy to induce a real danger: secondary bacterial infection. If other parts of the body are stabbed by a tank fish, it will cause more intense pain, and in severe cases, it may cause death.

But being punctured in the heart by a stingray is not a dead end. In Florida, USA, an 81-year-old man, James Bertakis, tried to throw out one of the stingrays on his boat, when the stingray suddenly stuck out a foot-long spine and stabbed directly into the old man's heart. But unlike Alvin, Bertakis resisted the urge to pull the spines off and instead took the right approach and surgically removed them. The operation was successful and the old man was rescued.
A little research will reveal that stinging hearts by stings may not be that rare. Five years ago, a 33-year-old snorkeler was stabbed in the heart by a redfish at Coogee Beach in Sini, Australia. In this accident, the fish pulled out its spines as it left. The lifeguards rescued the injured and took him to the hospital in time, but he was still frightened and his heart was pounding.
He gushed a lot of blood out of his torn coronary arteries, and this seemed to save him, because the venom was washed away when the blood flowed out, so he recovered and was discharged from the hospital only 6 days later.
The main reason stingray hurts people is that a large number of beaches and shallow seas have been developed into tourist resorts, which has caused marine animals to lose their habitat and conflicts with humans are increasing. If human beings cannot reflect on themselves in the process of resource development and utilization, then the incidents of poisonous fish hurting people will continue to be staged.
