Soft black cone snail
Heart worm is a kind of conch that is common near coral reefs in equatorial waters. Its largest individual can grow to about 23 cm. There are about 500 different species of heartworms in the world. This marine animal is a carnivore and usually feeds on marine worms, small fish and even other mollusks. Because of their slow movements, heartworms have to use poisonous harpoons (called poisonous tongues).
There are hundreds of different components in the venom of cardioplegia, and there are great differences among different species. These different toxins are called conotoxin, which includes different peptides and targets specific nerve channels or receptors. This toxin also contains analgesic ingredients, which can make the prey very calm before death. Some cardioplegia solutions contain tetrodotoxin, which is the same as neurotoxin in puffer fish. This toxin exists in puffer fish and blue-ringed octopus.
The toxin of a chicken heart snail is enough to kill 10 people. Its toxin usually targets small fish. Because humans and fish have similar nervous systems, humans are also vulnerable to the attack of the chicken heart snail. Experiments show that the victim of the chicken heart snail has no pain before he dies. Scientists have found more than 65,438+000 compounds in the toxin of the chicken heart snail, including compounds that block the transmission of information by the nervous system.
The bright colors and patterns on the surface of the heart-shaped snail can easily attract curious people to pick them up, so the tragedy happened. So far, there have been more than 30 deaths caused by the venom of the heart snail. There is also a kind of chicken-heart snail, which people usually call "cigar snail", which means that after being stung by it, there is usually only time left to smoke a cigar to save it.
Deadly beauty-poison dart frog
Poison dart frogs have some of the strongest toxins. The poisonous glands of this amphibian all over the body will produce some alkaloids that affect the nervous system. The most poisonous species is Bacillus flavus (Leptodactylis) in Colombia, which can hurt people as long as it is touched. Toxins can be absorbed by undamaged skin, causing severe allergies. The local people didn't kill the frog to extract the toxin, but just cut the spear of the arrow gun across the frog's back and set it free.
Other poison dart frogs are not so lucky. Several tribes in Colombia used different poison dart frogs to provide toxins to smear on the spears of arrow-blowing guns. Worm fire valley people insert sharp sticks into the frog's mouth until the frog releases foam of toxic alkaloids. A poison dart frog can provide 50 spears containing the required toxin, valid for one year. Obviously, bright and poisonous colors enable these frogs to hunt boldly during the day. Feeding on ants, termites and other small creatures living in the litter layer of tropical rain forest. Any creature that tries to eat them, if alive, will not eat them again, so they have no natural enemies except humans. They breed all year round. Frogs lay jam-like eggs on the ground and are guarded by one of their parents, or come back to watch them and often get wet. The newly hatched tadpoles are taken to a suitable puddle, tree hole or pineapple tree by one of their parents. After they have the viability, some of them.
Many poison dart frogs have bright skin colors, mostly with red, yellow or black stripes. These colors are often used in the animal kingdom to warn other animals that they are unfit for eating. These colors make poison dart frogs look very different-they don't need to hide from the enemy because attackers are afraid to get close to them. The most deadly toxin comes from the family frog produced in Colombia, South America, and only 0.0003 gram is enough to poison a person.
Terrible clown
Poisonous fish can be divided into two kinds: poisonous gland fish and poisonous fish. The most poisonous stickleback in the world is the poisonous catfish. They are ugly but colorful, ugly and love to dress up. They live in tropical waters of the Indian Ocean and the Pacific Ocean. Poisonous catfish belong to Cetaceans. Also known as the stone fish and the "ninja" on the sea floor, it has a large poisonous gland, which passes through 13 upright backstab on its back, poisoning the victim within 6 hours. It has a second respiratory system, so it can survive for more than 10 hours without water. Its tough thorns can pierce rubber soles and skin. However, despite this,
The poisonous tail of Palestinian scorpion in the desert
Palestinian scorpions, the most poisonous scorpions on the earth, rank fifth in the list of poisonous kings. At the end of its long claw is a pliers with a lot of venom, and its fangs are enough to penetrate human nails. When you don't pay attention to stab you, the powerful venom released by pliers will make you extremely painful, convulsive, paralyzed, and even stop your heart or respiratory failure. Unlike most spiders who live a quiet life, this little guy is very aggressive and will lift his hind legs when disturbed. The male spider is smaller than the female spider, but its venom is five times more poisonous than the female spider. It mainly lives in Israel and other parts of the Far East.
Death fairy box jellyfish
The gentlest killer in the ocean. It is considered to be the most poisonous creature in the world. It can kill people after being stung for 30 seconds. The toxin of a box jellyfish is enough to kill 60 adults. If it is box jellyfish poisoning, it will die within 0 seconds to 4 minutes without treatment.
Australian box jellyfish is a light blue transparent jellyfish, shaped like a box, with four obvious sides, each side is 20 cm long. Box jellyfish has 60 tentacles 3 meters long, each of which is covered with stinging cells for storing venom. At present, the only way to avoid being attacked by sea wasps is to avoid swimming in the waters infested by this jellyfish. At present, warning signs have appeared on all beaches in northeastern Australia to remind people of this jellyfish. Scientists are trying to find a more effective antidote.
Poison in the Mouth-Spiny Throat Dragon
The most poisonous fish in the world is Sparus striatus, which is distributed in the Red Sea, India and the Pacific Ocean. They are ugly in appearance, but brightly colored. Their ovaries, livers, intestines, skin, bones and even blood all contain a neurotoxin-tetrodotoxin. Tetrodotoxin is puffer fish, you can eat it, but you have to risk your life. 1774, a captain in james cook recorded in his nautical diary that his assistant bought a fish from the local aborigines that day. It looks a bit like a mola fish. Its head is big, long and ugly. Because it was getting late, he only tasted fish liver and roe, but after 3 o'clock in the morning, he developed poisoning symptoms, dizziness and numbness in his limbs, and another pig was paralyzed by eating fish viscera.
The most poisonous snake on land-inland taipan.
The inland Taipan snake, formerly known as the inland shield snake, is smaller than the ordinary Taipan snake, and the adult snake is only about 2 meters (9 feet). The inland Agkistrodon halys has a flat head and slightly sharp eyes. The inland viper is the most poisonous snake on land. The absolute amount (LD50) required by the venom of Agkistrodon halys to kill half of the tested organisms is only 0.02 1mg/kg. However, the detoxification amount reached 12.5 mg-40.0 mg, which was 300 times more toxic than rattlesnake and about 20 times that of king cobra, and was equivalent to the lethal situation of hook-nosed sea snake, ranking in the top ten in animal toxicology. Every time it bites a victim, it can poison 20 tons of prey in 24 hours. This is equivalent to the weight of 250,000 mice, 100 adults or two African elephants. The venom of Agkistrodon acutus inland can completely kill an adult in 15 seconds. The inland Agkistrodon acutus has gray to yellowish brown scales, sometimes with thin black edges. The trunk is brown or olive green, the abdomen is yellow and white, the head is black or with black stripes, and the fangs are 7.0 long.
The ubiquitous funnel web spider
Funnel spider is one of the most poisonous spiders in the world. It is distributed in Australia, and it carries enough venom to kill 5 to 8 people. The largest funnel spider is the size of a palm, and its fangs are 1 cm long, which can pierce people's toenails. What is chilling is that the male of this spider is extremely aggressive to people, and will appear on the desk, kitchen and shoes in the living room when mating. And anywhere it thinks it can find the female spider. This funnel spider will attack humans continuously, and the victim will not only feel severe pain, but also sweat profusely, and then the venom will enter the nerve and cause death. This process only takes a few minutes.
The most poisonous snake in the world-Agkistrodon halys.
At present, there are about 700 kinds of snakes in the world. The most poisonous snake is Belcher Sea Snake, which is many times more toxic than any land snake. Although the Belcher sea snake is the most poisonous snake in the world, it is quite gentle in temperament and will only bite unless it is treated with strong hostility. These biting incidents usually occur when fishermen are fishing, and Belcher sea snakes are not always malicious and rarely inject a lot of toxins into their opponents. Based on these factors, Belcher sea snakes are not regarded as extremely dangerous snakes. In addition, Belcher sea snakes are often mistaken for hook-nosed sea snakes and green-ringed sea snakes. In fact, the toxin power of Belcher sea snakes is quite mysterious. Some reptiles and snake lovers will think that the toxins of Enhydrina schistosa and Oxyuranus microlepidotus are more dangerous than Belcher sea snakes.
The plague in the sea-sea snake
Gelsemid sea snakes are slender, grayish white with discontinuous light blue stripes. There are large shovel scales under the jaw, and the skin on the head is slack, which can make the mouth wide. The common gelsemid sea snake is very toxic and dangerous, and there is no degradable drug. It lives in the ocean from the Persian Gulf coast to the Philippines and northern Australia. It is so toxic that the venom injected is enough to kill 50 people.
The most poisonous woman is RedbackSpider.
In South Africa, the black widow spider is called the button spider. The red-backed spider may not have thought that it is one of the two most poisonous spiders in Australia-its original name is black widow spider.
The black widow may be the most famous poisonous spider in the world, but generally speaking, being bitten by a black widow is not fatal. The black widow's abdomen has a red hourglass pattern, which is its iconic feature. The black widow spider is black all over, and the male spider has red spots on his abdomen, which is 2-8 cm in length. Because the female of this spider will kill her spouse immediately after mating, it is named "black widow" by the people.
The black widow spider is a kind of spider with strong neurotoxin. It is a large widow spider, which is widely distributed and usually grows in urban residential areas and rural areas. Its poison is more poisonous than rattlesnake, but its death rate is slightly lower because of less secretion. "Black Widow" spiders are often not noticed when they bite. The wound is like a pinhole, so even if they are bitten, you may not be aware of it. At first, you usually only notice slight swelling and vague marks on the wound. However, after a few hours, the pain of the wound began to intensify and the wound showed signs of hardening. Other symptoms of being bitten include chills, fever, vomiting and severe abdominal pain. Patients with mild poisoning can be discharged after one or two days of treatment. If it is serious, it will stay in the hospital for a month or even lead to life-threatening. The venom of the black widow spider can promote the release of the neurotransmitter acetylcholine. Acetylcholine acts on muscles, which can cause muscle contraction. Generally speaking, the venom of the black widow spider is a great threat to children and the weak. Black widow spiders have red hourglass patterns on their bellies regardless of gender.
You didn't discuss the poisonous blue ring octopus.
The blue-ringed octopus is beautiful, but it is poisonous under its beautiful appearance. At present, the blue-ringed octopus is only found in the southern waters of Australia. The blue-ringed octopus is shy by nature, and likes to hide under rocks and come out for food at night. It has beautiful blue links on its wrists and feet. When it is in danger, the dark ring on its body and claws will emit dazzling blue light and send a warning signal to the other side. The blue-ringed octopus can produce tetrodotoxin. The blue-ringed octopus is the only known organism that can produce tetrodotoxin. Tetrodotoxin can paralyze the central nervous system and nerve endings, and its toxicity is 1000 times higher than that of sodium cyanide, and 0.5 mg can cause death. The venom of an octopus is enough to kill 10 people, and in severe cases, it dies within minutes after being bitten. At present, there is no effective antimycin prevention.
Blue-ringed octopus and puffer fish are completely different species, but they can both produce tetrodotoxin. The blue-ringed octopus is very toxic and can be fatal when bitten. Marine fishermen need to be careful. The blue-ringed octopus can kill a person with one bite, and it can't be saved. Its sharp mouth can penetrate the diver's diving suit, and at the same time, it will spray toxic ink, which is enough to kill an adult in a few minutes. What is even more frightening is that at present, human beings can't solve the problem from the blue-ringed octopus.
The most poisonous beetle-turtledove
Banao, alias "tabby cat", "dragon oyster" and "gallbladder", is the most poisonous beetle. There are more than 2,300 kinds of banao in the world, but there are 29 kinds in China. Banao is covered in black fluff, with slender oval wings and soft texture, and is 1 1. Harm to soybean, peanut, eggplant and other crops. When it is disturbed, it will secrete yellow venom from the joints of its feet to defend itself. This yellow venom contains strong cantharidin, which is very toxic and can destroy the cells and tissues of higher animals. When it comes into contact with human body, it will cause skin swelling and blistering.
