According to a recent report by American Life Science Network, the list of the top ten most dangerous marine animals is somewhat subjective, but it is based on relevant research. These studies are aimed at finding the most frightening marine animals. They are all very terrible offensive and 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 oceans. 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. Killer whales rarely attack people; Octopus is famous for its aggressiveness, but its danger can't be compared with the 10 species on the list. As for sea cucumbers, few people associate them with the word "danger"; Although the name of piranha sounds chilling, the deadly attack on human beings is more just a usual means of hearsay or horror movies, which rarely happens in real life.

1. Box jellyfish

In the ranking of the top ten most dangerous marine animals, the box jellyfish won the most dangerous title with its unique lethality. There are many kinds of box jellyfish living in the ocean. Although there is no official record, a lot of anecdotal evidence shows that dozens of people or even 100 people are killed by box jellyfish every year. According to the data provided by the National Science Foundation, in the Philippines alone, 20 to 40 people die every year from the stings of box jellyfish. The Science Foundation said: "In many countries, the tragedy caused by box jellyfish does not need to issue a death certificate, so the number of deaths caused by box jellyfish in the world may be underestimated to a large extent." Australian box jellyfish has dozens of tentacles, each of which can reach a maximum length of 15 feet (about 4.57 meters), and it contains enough toxins to kill 60 people. The stinger of a box jellyfish named "Chironex fleckeri" can kill people in just 3 minutes. Box jellyfish living in Hawaii, Florida and other parts of the United States can cause heart failure in the stabbed person. The most terrible member of the box jellyfish family is the capuchin jellyfish, and the pain caused by stabbing can compete with lightning. So far, it is still unknown how many people were attacked by the capuchin jellyfish.

2. Tiger sharks

Because of the promotion of related films, the great white shark attracted everyone's attention. But the most terrible shark is not a great white shark, but a tiger shark, and more people actually die from them. Except poisonous snakes, there are few animals that can make people naturally afraid, and sharks are one of them. According to the National Oceanic and Atmospheric Administration, tiger sharks will bite almost anything, including fish, seals, birds, squid, small sharks, dolphins, license plates and even old tires. Their height can reach 18 feet (about 5.48 meters) and their weight can reach 1 ton, so 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. Records show that great white sharks attack people more often than tiger sharks every year, but the number of accidents that cause death is not as good as that of tiger sharks. We have only a few reasons to explain why sharks missed the title of the top ten most dangerous marine animals: the number of shark attacks on people around the world is about dozens every year, which is roughly the same as that of lightning strikes in the United States. In 2008, only four people in the world were killed by sharks.

3. stone fish

There are two main reasons why stone fish rank among the top three: one is that they are the most toxic fish in the world; The other is that they are masters of camouflage in the animal kingdom, and they can "lurk" quietly on the seabed like stones, waiting for their prey to take the initiative to come to the door. 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 the attack of sharks or other predators. The released venom can cause temporary paralysis, and it will die 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. It is puffer fish. The puffer fish, also known as "puffer fish", carries more toxins than cyanide. Specially trained Japanese chefs will make safe parts into delicious food, but the tragedy of diners dying of poisoning also happens frequently. The name "air drum" comes from the strong water absorption ability of puffer fish, and the volume after inhaling a lot of water is twice as large 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 successfully rank among the list. Although it also releases terrible venom like its terrestrial counterparts, the sea snake's lifestyle is more like a "marine hermit", so it is 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 rarely attack humans, preferring to kill eels, shellfish and shrimps.

Step 6

Also known as "lion fish", the giant salamander is a popular pet in domestic fish tanks. This kind of fish looks docile, but the fan-shaped spines are also surprisingly toxic. The National Oceanic and Atmospheric Administration said that although it will not cause fatal injuries to humans, being stabbed by thorns will also cause headaches, vomiting and breathing difficulties, and it is by no means an annoying guy. Usually, the pain caused by stabbing lasts about half an hour, but some people report that their tingling lasts for several weeks. The giant salamander is not a very aggressive animal. Therefore, the people who are "hurt" by the giant salamander are often the owners of domestic fish tanks, not divers or fishermen.

7.crocodile

Saltwater crocodiles have always held the title of "one of the fiercest predators in the wildlife kingdom". Their length can exceed 20 feet (about 6 meters) and their weight can reach 3,000 pounds (about 1360 kilograms). Animals including monkeys, kangaroos, buffaloes and even sharks have become their targets. In the process of hunting, saltwater crocodiles win by sheer strength. They can forcibly drag buffaloes into the water and sometimes attack humans. They first use their powerful jaws to bite their prey, and then use the so-called "death roll" to drag their prey into the water. "Death Roll" can also scatter large animals in half.

8. sting rays

The stingrays are commonly known as "stingrays". From this name alone, we can easily guess that they are a very dangerous animal. In 2006, steve irwin, a crocodile hunter, died after being stabbed in the heart by a stingray. Owen's misfortune undoubtedly enhanced the reputation of stingray, a close relative of sharks, as a "dangerous animal". At the tail end of the stingray, there is a stinger with a serrated edge about 8 inches (about 20.32 cm), and the substance that constitutes the stinger is the same as the substance that constitutes the shark scale (called "shield scale"). When you feel threatened, the serrated stinger will harden, like a sharp steak knife. Sting will release venom, causing fatal injuries to predators. Mott Marine Laboratory said: "This venom is mainly a protein-based toxin that can cause great pain to mammals and may affect heart rate and breathing." It is worth mentioning that stingrays usually do not attack humans.

9. Sea lions

The reason why sea lions can rank among the top ten most dangerous marine animals is that they are highly territorial and will never show mercy to intruders. Sea lions are known as intelligent and trainable animals, and they are the big stars in zoos, but they are also famous in the animal kingdom for their biting behavior. In 2006, a series of sea lion attacks occurred in Manhattan Beach, Newport Beach and the coast of San Francisco in California, which raised the concern of managers and scientists. Some researchers believe that sea lions may have eaten some fish contaminated by toxic algae before these abnormal behaviors occur. "Like all wild animals, seals and sea lions are unpredictable and can become aggressive animals," the city government of San Diego warned on its website. They have sharp teeth and may attack people, especially if they are forced too tightly or harassed. "

10. moray eel

Eel has a snake-like body, a prominent nose and mouth and a wide jaw. They are members of the fish family and can be up to 8 feet (about 2.43 meters) long. Looking at this primitive animal, we will naturally associate it with death. According to the National Oceanic and Atmospheric Administration, moray eels have strong jaws and sharp teeth, and the serrated wounds caused by tooth bites are easily infected by bacteria in their mouths. If moray eels bite people out of fear or accident (especially when foraging), they usually choose to let go and 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. Experts from the National Oceanic and Atmospheric Administration put forward two suggestions on how to avoid being bitten by moray eels: one is never to put your hands in underwater rocky caves and cracks; The other is, never feed the eel. It is worth mentioning that many eel bite accidents are caused by feeding.
