First place box jellyfish
Speaking of jellyfish, many people who have been to the aquarium will feel beautiful and have an impulse to touch them, but not all jellyfish are so beautiful and lovely. In the depths of the ocean, there is such a box jellyfish, whose toxicity is prohibitive, ranking first among highly toxic marine life. It is said that the venom of a box jellyfish can kill 250 people instantly. If the poisoned person is in the water, it may be.
Box jellyfish, also known as "sea wasp", is a highly toxic creature, mainly distributed in northern Australia, the eastern coast and the western Pacific Ocean. It has a brain and a heart. Its tentacles are covered with nerve cells. When it feels threatened, the box jellyfish will pierce each other's skin with its tentacles and release venom. The released venom will invade the nervous system of the body, paralyze muscle tissue and respiratory system, and then lead to cardiac arrest. The time from poisoning to death is only a few minutes.
Second place blue-ringed octopus
There is a common sense in nature that the brighter the colors, the more toxic the creatures are, so when you see those colorful animals, try to stay away from them. The blue-ringed octopus is the best representative. Blue-ringed octopus and blue-finned jellyfish are the most poisonous marine creatures known at present. The blue-ringed octopus is very small, with a length of only 15cm.
The skin on the body surface is yellowish brown, but they can also change color according to different environments. They are hidden in the depths of the ocean and are generally not easy to find. There are many bright blue rings on their bodies, including their tentacles. When they feel threatened, these blue rings will emit dazzling blue light as a warning to each other.
The blue-ringed octopus has strong tetrodotoxin, which is used to protect itself and its prey. This little octopus can kill people with one bite. Despite its small size, the blue-ringed octopus carries enough toxins to kill 26 adult octopus at a time in a few minutes. At present, there is no effective antitoxin to prevent it.
Third place Belcher sea snake
There are about 50 species of sea snakes in the world. The Belcher sea snake was once one of the most poisonous snakes in the world. It lived around the rocks in the ashmore Islands in northwest Australia, and its length could reach about 3 meters. They live in coastal waters, especially saltwater estuaries, and feed on fish. According to the toxicity of venom per unit volume, its toxicity is 20 times that of cobra.
The venom of Belcher sea snake is similar to that of land snake venom, and it is also a mixture of protein, which mainly contains neurotoxins, muscle toxins and various enzymes. Its toxicity is relatively stable, and it is also stable in acid and alkali environment. The venom it releases can paralyze prey in just a few seconds and eventually lead to death. At present, there is no serum to detoxify.
Fortunately, however, Belcher sea snakes are gentle and rarely attack humans. Unless they are treated with strong hostility, they will only bite people. For example, when fishermen are fishing and collecting nets, on the other hand, the Belcher sea snake's fangs have little effect and secrete less venom, so it is not among the highly dangerous snakes. But be careful when you meet the Belcher sea snake.
No.4 stone fish
Stonefish are widely distributed in any sea area, but most of them are at the junction of tropical and salty fresh water. Its "fatal sting" is described as the most painful sting of human beings. Stone fish is not surprising in appearance, only about 30 cm long. I like to hide under the sea or rocks and disguise myself as an inconspicuous stone. Even if you stand next to it, it won't move, so that you can't find it.
If you don't step on it carefully, it will immediately fight back rudely. 12 to 14 needle-like backstab on your back can easily penetrate your body, causing you to be poisoned quickly. After poisoning, the human body will immediately have difficulty breathing and severe pain all over the body, accompanied by symptoms such as aversion to cold, fever and nausea, which will lead to fainting, mental disorder, bile vomiting, heart failure, blood pressure drop, and then nonsense and nausea.
Article 5 puffer fish
There are about 100 species of puffer fish in the world. The most striking feature is that they suck water or air into their abdomen when they are frightened. Expand into a sphere two or three times larger than the original one to scare off the enemy. Although it is called "puffer fish", it swims between the sea and the river.
Although cute, it is extremely harmful. As the second most toxic vertebrate in the world, tetrodotoxin is mainly concentrated in ovary, liver and blood, followed by eyes, gills and skin, and some kinds of muscles also contain toxins. The chemical properties of this toxin are relatively stable, and it can not be destroyed quickly after frying, boiling, salting and sun exposure, so the mortality rate of human and animal poisoning is extremely high.
Tetrodotoxin mainly paralyzes nerve endings and central nervous system, antagonizes cholinesterase in blood, seriously paralyzes neuromuscular system, prevents neuromuscular conduction, and causes central nervous system disorder. The incubation period of puffer fish poisoning is very short, as short as 10 ~ 30 minutes and as long as 3 ~ 6 hours. The onset is acute and fierce. If the rescue is not timely, he will die within 10 minutes at the earliest and 4 ~ 6 hours at the latest. The toxin of a medium puffer fish can kill more than 30 people.
Sixth place chicken heart snail
Chicken heart snail, also known as conus, mainly grows in tropical waters and generally lives in warm waters. There are about 500 different kinds of chicken-heart snails in the world. This marine animal is a carnivore and usually feeds on marine worms, small fish and even other mollusks. When it hunts, it will ambush its body in the sand, revealing only its long nose. This can not only get oxygen, but also monitor the movements of prey.
Its tip hides a small mouth from which a poisonous needle can be ejected. Venom contains hundreds of different components, and the components of different components vary greatly.
Some chicken heart snails contain tetrodotoxin. At the same time, it also contains analgesic ingredients, which can make the prey motionless and very calm before death. Because the surface is bright, it is easy to attract people to pick it up. So far, there have been more than 30 cases of death caused by the venom of the heart snail. The toxin of a chicken heart snail is enough to kill 10 people.
Among all kinds of chickpeas, chickpeas that feed on fish are the most poisonous, followed by mollusks, and those that feed on sea worms will not kill humans. Are you surprised after reading it? Obviously, some creatures are lovely and beautiful, but they are extremely toxic. In the ocean, there are many tiny poisons hidden, which are beautiful but highly toxic.
On the earth where we live, there is almost no more dangerous and mysterious place than the ocean. The sea is extremely deep, and in the depths of the sea floor, there are probably many highly toxic creatures that humans have not discovered so far. Therefore, we should always be in awe of the ocean.
