According to a recent report by the American Life Science Network, the list of the top ten most dangerous marine animals is subjective, but it is based on relevant research. These studies are aimed at finding the most terrible marine animals. They are all terrible and aggressive, which can bring great harm and even death to human beings. Usually this kind of injury and death can be avoided. Among the marine animals on the list, the main "killing" places of two animals are fish tanks and restaurants at home, not their home ocean. Therefore, we can take measures to avoid such tragedies. It is worth mentioning that some very powerful competitors did not appear in the rankings, including killer whales, octopus, sea cucumbers and piranhas. Black whales rarely attack people; Although octopus is famous for its aggressiveness, its danger cannot be compared with the 10 species on the list. As for sea cucumber, few people associate it with the word "danger"; Although the name of piranha sounds chilling, its deadly attack on human beings is more just the usual means of hearsay or horror movies, and it rarely happens in real life.

1. Box jellyfish

In the selection of the top ten most dangerous marine animals, the box jellyfish won the most dangerous title for its unique lethality. There are many kinds of box jellyfish living in the ocean. Although there is no official record, a large number of anecdotal evidence shows that dozens of people or even more than 100 people are killed by box jellyfish every year. According to the data provided by the National Science Foundation of the United States, in the Philippines alone, 20 to 40 people die every year from the sting of box jellyfish. The Science Foundation said: "In many countries, the tragedy caused by box jellyfish does not require a death certificate, so the number of deaths caused by box jellyfish around the world may be greatly underestimated." Australian box jellyfish have dozens of tentacles, each of which can reach 15 feet (about 4.57 meters). It contains enough toxin to kill 60 people. The sting of a box jellyfish named Chironex fleckeri can kill people in as short as 3 minutes. Box jellyfish living in Hawaii, Florida and other parts of the United States can cause heart failure in victims. The most terrible member of the box jellyfish family is cephalopods, and the pain caused by stabbing can be comparable to that caused by lightning. So far, how many people have been attacked by cephalopods is still unknown.

2. Tiger sharks

Because of the publicity of related films, great white sharks have attracted everyone's attention. But the most terrible shark is not a great white shark, but a tiger shark. More people actually died in the jaws of a tiger. Apart from poisonous snakes, there are few animals that can make people naturally afraid, and sharks are one of them. The National Oceanic and Atmospheric Administration says tiger sharks will bite almost anything. These include fish, seals, birds, squid, sharks, dolphins, license plates and even old tires. Their length can reach 18 feet (about 5.48 meters) and their weight can reach 1 ton. They are well-deserved "marine killers". Tiger sharks can be found in many tropical and temperate waters, especially around the islands in the central Pacific Ocean. Great white sharks attack people more times each year than tiger sharks, but the number of fatal accidents is less than tiger sharks. We have only a few reasons to explain why sharks have missed the title of the top ten most dangerous marine animals: the number of shark attacks every year is about dozens, which is roughly the same as the number of lightning strikes in the United States. In 2008, only four people died in the world.

3. Stone fish

There are two main reasons why stone fish can rank among the top three: first, they are the most poisonous fish in the world; On the other hand, they are masters of camouflage in the animal kingdom, and they can "lurk" quietly on the seabed like stones, waiting for their prey to come to the door actively. Although the stone fish will not take the initiative to attack, no one dares to risk close contact with it. The spines on the back of the stone fish can resist attacks by sharks or other carnivores. The released venom will cause temporary paralysis and death without treatment.

4.puffer fish

There is an animal that can kill people even if it is made into delicious food and put on the table. Is puffer fish, also known as "puffer fish", carrying more toxins than cyanide. Specially trained Japanese chefs will make the safe parts into delicious food, but the tragedy of diners dying of poisoning often happens. The name "puffer fish" comes from the strong water absorption ability of puffer fish. After inhaling a lot of water, the volume is twice as normal. It is worth mentioning that puffer fish also plays a life-saving role, and drugs made of tetrodotoxin can be used to treat withdrawal symptoms caused by taking drugs such as * * * * * *.

5.sea snakes

Humans have a natural fear of snakes, and it is this fear that makes sea snakes successful on the list. Although they will release terrible venom like their counterparts on land, sea snakes are more like "sea hermits", so they are not very dangerous. When it comes to toxicity, people often compare sea snakes with cobras. The venom they release can paralyze their prey in just a few seconds and eventually lead to death. Fortunately, they seldom attack.

Step 6

Giant salamander, also known as "lion fish", is a popular pet in domestic aquariums. This fish looks docile, but its fan-shaped spines are also surprisingly toxic. According to the National Oceanic and Atmospheric Administration, although it will not cause fatal harm to human beings, it will also cause headaches, vomiting and breathing difficulties, and it is by no means a nuisance. Usually, it will be caused by thorns. Their stinging lasted for several weeks. The giant salamander is not a very aggressive animal. Therefore, it is often the owner of the domestic fish tank who is "hurt" by the giant salamander, not the diver or fisherman.

7.crocodile

Saltwater crocodiles have always been known as "one of the fiercest carnivores in the wild animal kingdom". They can be more than 20 feet (about 6 meters) in length and weigh up to 3000 pounds (about 1 360 kilograms). Animals including monkeys, kangaroos, buffaloes and even sharks have become their targets. In the process of hunting, saltwater crocodiles win by sheer strength, and they can forcibly drag buffaloes into the water. Sometimes they attack humans. They first bite their prey with their powerful jaws, and then drag their prey into the water with the so-called "death roll". The "Death Roll" can also break up large animals by half.

8. sting rays

Stingrays are commonly known as "stingrays". From the name alone, we can easily guess that they are a very dangerous animal. In 2006, crocodile hunter steve irwin died after being stabbed in the heart by a stingray. Owen's misfortune undoubtedly enhanced the reputation of stingrays, which are close relatives of sharks. The tail of stingrays is about 8 inches long. The substance that makes up the stinger is the same as the substance that makes up the shark scale (called "shield scale"). When it feels threatened, the jagged thorn will harden like a sharp steak knife. Sting will release venom, causing fatal damage to predators. Mott Marine Laboratory said: "This venom is mainly a protein-based toxin, which will bring great pain to mammals and may affect heart rate and breathing." It is worth mentioning that.

9. Sea lions

Sea lions are among the top ten most dangerous marine animals because they are very territorial and will never show mercy to intruders. Sea lions are regarded as intelligent and trainable animals and the big stars of zoos, but they are also famous for their biting behavior in the animal world. In 2006, a series of sea lions attacked people in Manhattan Beach, Newport Beach and the coast of San Francisco, California. This has attracted the attention of managers and scientists. Some researchers believe that before these abnormal behaviors, sea lions may have eaten some fish contaminated by toxic algae. "Like all wild animals, seals and sea lions are unpredictable and may become aggressive animals," the city government of San Diego warned on its website. They have sharp teeth and may attack people, especially when they are pushed too hard or harassed. "

10. moray eel

Eel has a snake-like body, a prominent nose and a broad chin. They are members of the fish family and can be as long as 8 feet (about 2.43 meters). Looking at this primitive animal, we naturally think of death. According to the National Oceanic and Atmospheric Administration, sea eels have strong jaws and sharp teeth. The serrated wounds bitten by teeth are easily infected by bacteria in the mouth of sea eel. If sea eels bite people out of fear or accident (especially when foraging), they usually choose to let you live. During the day, moray eels often lurk in cracks and caves and come out to hunt after nightfall. They mainly feed on fish or other animals that can be captured by them. How to avoid being bitten by moray eel, country, ocean and country. The other is, never feed eels. It is worth mentioning that many eel bites are caused by feeding.
