Blue-ringed octopus
Blue ring octopus, belonging to the octopus family, commonly known as the blue circle octopus, leopard print octopus is widely distributed in the Taiping Sea between Japan and Australia, is a very small octopus species, the arm span does not exceed 15 cm. It can feed small fish, crabs, shrimp and crustaceans, and will paralyze prey with strong toxins. In the ocean, the blue-ringed octopus is one of the most poisonous creatures, and a bite from this small octopus can kill people. But these octopuses don't actively attack humans unless they are greatly threatened. The octopus is small, but secretes enough venom to kill people in a single bite. Since there is currently no antidote, it is one of the most toxic marine organisms known. Its sharp mouth is able to penetrate the diver's wetsuit. The venom in its body can be built into the deadly place in minutes after the attack, and there is still no medical way to detoxify it. There is almost no pain after being stung by this octopus, and it is an hour before the toxicity begins to attack. Fortunately, blue-ringed octopuses are not aggressive and rarely attack humans. The blue-ringed octopus is one of the most venomous animals known to be poisonous. Despite its fairly small size, a blue-ringed octopus carries enough toxins to kill 26 adults at a time in minutes. There is currently no effective antitoxin to prevent it. The venom of the octopus can prevent blood clotting, causing the wound to bleed heavily, and it feels stinging, and finally the whole body has a fever, difficulty breathing, the heavy ones are fatal, and the light ones also need to be treated for three or four weeks to restore health.
Belcher Sea Snake
The Belcher sea snake is a venomous sea snake of the genus Sea Snake of the suborder Cobra family, once one of the most venomous snakes in the world, living around reefs in the Ashmore Islands in northwestern Australia.
Its venom is similar to that of land snake venom and is a mixture of multiple proteins, mainly containing neurotoxins (about 52.3% of crude venom), muscle toxins (about 32.2% of crude venoms) and various enzymes. Its toxicity is relatively stable, after 100 °C, 5 minutes of treatment can still maintain toxicity, in the acid, alkali environment is also stable. His temperament is rather mild, and he will not bite unless he is treated with strong hostility. These bites usually occur when fishermen are fishing and collecting their nets. In addition, the poisonous fangs of the Belcher sea snake are not effective, and the amount of venom that can be secreted is not much. Due to various factors, it is not considered a highly dangerous snake. However, care is still required when dealing with this snake.
They have a mild temperament and prefer to inhabit shallow waters around the continental shelf and islands, rarely seen in open waters with a depth of more than 100 meters. Some prefer to stay in muddy waters on the bottom of sand or mud, while others prefer to move in the clear water around coral reefs. The Belcher sea snake is the most venomous sea snake in the world, 200 times more toxic than the king cobra in terms of venom per unit volume.
Stonefish
Stonefish is a collective name for a few poisonous marine fish species. Benthic, inactive, lives on rocky reefs, among corals, and on mud bottoms or estuaries. They are masters of camouflage in the animal kingdom, able to "lurk" on the seabed like stones, waiting for their prey to take the initiative to come to the door. Although the stonefish will not initiate an attack, no creature will dare to risk getting close to it. The spines on the back of stonefish are able to withstand sharks or other predators. The venom released can cause temporary paralysis that can lead to a death if left untreated.
Stonefish belong to the poisonous catfish family and are a collective term for several poisonous marine fish species. The representative species of stonefish is the rose poison scorpion, which can reach a body length of about 33 cm. The plesiosaur family also includes several other stout, warty fish, which are also poisonous, but not as notorious as stonefish. Some of the scorpionfish in the family Cyprinidae are also considered rock fish or stone fish. These fish grow on the south coast of Australia, and they resemble rocks or corals at sea. The venom of stonefish causes intense pain and shocks the poisoned animal to death.
Tank jellyfish
Box jellyfish, also known as cubic jellyfish, is a class of coelenterates. There are about 20 species, marine life. The hydra is small and the jellyfish is large. It will actively hunt fish, crabs and other animals. Box jellyfish is the common name for about 20 species of jellyfish in the coelenterate cubic jellyfish family, which is given this strange name because of its slightly rounded shape, resembling a square box. Tank jellyfish marine, hydra body small, jellyfish body large. The most representative of the box jellyfish is called the Australian box jellyfish, which mainly lives in the northeast coastal waters of Australia and often floats in the shallow waters off the coast of Queensland. The venomous poison of a tank jellyfish is enough to poison 60 adults, and if it is poisoned by a tank jellyfish, it will die if it is not treated within 1 second to 4 minutes.
The Australian tank jellyfish is a pale blue transparent jellyfish shaped like a box, with 4 distinct sides, each 20 cm long. The box jellyfish has 60 3-meter-long tentacles, and there are billions of poison sacs and poison needles on the tentacles, which are enough to kill 20 people, which shows the great toxicity and the fierceness of the killing.
Why the tank jellyfish is so toxic is not entirely clear, but researchers have found that its venom mainly damages the heart. The heart of a healthy person has millions of muscle cells, and these muscle cells are beating at the same rhythm. When the venom of the tank jellyfish invades the human heart, it will destroy the consistency of the rhythm of muscle cell beating, so that the heart cannot supply blood normally, resulting in rapid death. The study also found that acetic acid can kill the tentacles of tank jellyfish, so scientists recommend that visitors to Queensland to swim and dive should preferably bring a bottle of vinegar to use when encountering tank jellyfish.
blowfish
Puffer fishes (Tetraodontidae; puffer fishes) is a collective name for the teleost fish of the family Pufferfish, commonly known as pufferfish. Since ancient times, the puffer fish eaten in China have all lived in the river, and are named "puffer fish" because of the chirping sound similar to the sound of pigs when caught in the water. Pufferfish body is cylindrical, air sac, when encountering danger will inhale and expand, the general body length of 25-35 cm, pufferfish toxin is a colorless needle-like crystal, belongs to acid-resistant, high-temperature resistant animal alkali, for nature's most toxic non-protein substances. One in 50 million can anesthetize nerves in 30 minutes, the minimum lethal amount to the human body is 0.5 mg, and the toxins of pufferfish are mainly distributed in the ovaries and liver, followed by the kidneys, blood, eyes, gills and skin; while the sperm nest and muscles are non-toxic.
The incubation period of toxins in the pufferfish is 0.5 to 3 hours, and gastrointestinal symptoms such as nausea, vomiting, diarrhea, abdominal pain, followed by sensory and motor dysfunction, numbness in the lips, tongue, extremities and the whole body, and limb weakness. Eyelid insufficiency, ataxia, hoarseness, severe cases can appear dyspnea, arrhythmia and conduction block, coma; finally respiratory and circulatory failure, pufferfish toxin in the human body detoxification and excretion faster, if not dead after 8 hours can recover.
Embroidered spine ripe crab
Embroidered ridge ripe crabs, also known as mosaic crabs, their appearance is very beautiful, red and white patterns are very eye-catching on the body. Contrary to its appearance, its toxin can be said to be a "snake and scorpion beauty" in the true sense. Distributed in Japan, Fiji, Samoa, Australia, Singapore, the Malay Peninsula and hainan island in Chinese mainland, its whole body is covered with red and white mesh patterns, which is very beautiful. The embroidered ridge crab lives in seawater, often living in rocky bottoms or coral reefs from low tide lines to a depth of 30 meters. The lower limit of its survival altitude is -30 meters. The embroidered ridge ripe crab is the most poisonous crab known, and some of their bodies contain puffer fish poison, some contain paralytic shellfish poison, and some contain sea anemone poison. The toxins in an adult embroidered crab can poison 45,000 mice.
Its whole body is covered with red and white mesh patterns, which is very beautiful. The body length of the embroidered ridge ripe crab is about 4 cm and the body width is about 8 cm. The cephalothorax carapace is transversely oval in shape and has a smooth surface. Clearly partitioned, the anterior lateral margin is thin plate-like, behind the outer eye socket is divided into four lobes, the claws are asymmetrical left and right, the fingers are sharp, the feet are wide and flattened, there are bundles of bristles, the cheek area is densely covered with fluff, and the whole body has a red and white network pattern, the nail length is about 4 cm, and the nail width is about 8 cm.
Chicken heart snail
Chicken heart snail, also known as "taro snail", mainly grows in tropical seas, generally lives in warm seas, belongs to the mollusk phylum, gastropods, taro snail family, is a coastal coral reef, beach life on the beautiful snail. The shell of the chicken heart snail is sharp at the front and the rear end is thick, shaped like the heart or taro of a chicken. It has many varieties, in different colors and patterns, and is a highly poisonous marine creature, because its tip part hides a small opening with poisonous teeth that can shoot venom from here, enough to make the injured person scream for life. The toxin of a chicken heart snail is enough to kill 10 people, and its toxin is usually aimed at small fish, which makes humans equally vulnerable to chicken heart snails because humans and fish have similar nervous systems.
The venom of chicken heart snail contains hundreds of different components, and the composition of the ingredients varies greatly between different species. These different toxins are called taro toxins, and they include different peptides that target a particular neural channel or receptor. This toxin also contains analgesic ingredients that can make prey unable to move and become very calm before dying. There are also chicken heart snails that contain tetrodotoxin, the same neuro paralysis toxin in puffer fish, which is found in puffer fish and blue-ringed octopus. The brilliant color and pattern of the surface of the snail can easily attract those who are curious to pick them up, and tragedy happens precisely because of this. To date, more than 30 deaths due to venom of chicken heart snails have been recorded.
etc. refers to anemone
Isonotem, is a species of anemone in the genus Anemone in the family Anemone family. The body color varies greatly, with the cylinders appearing dark milky yellow, dark red, reddish brown, or rose red. The isometric anemone is a petite sea anemone that lives mainly in the Mediterranean Sea, northern Scotland, and the eastern Atlantic Ocean at a water depth of about 2 meters. The anemone has 6 full circles of tentacles, the largest of which is 192, which is very scary. Accidentally stabbed by an anemone, its toxin can cause the animal's blood pressure to drop rapidly, slow down the heart rate, suppress breathing, and eventually die.
Alone or in groups, in the shadows or caves of shallow sea rock walls. Isometric anemones are distributed in the Mediterranean, eastern Atlantic and northern Scotland, with a water depth of 2 meters, the body color changes greatly, the cylinder is dark milky yellow, dark red, reddish brown or rose red; the mouth plate is lilac red or reddish brown; the mouth margin is light milky yellow; the tentacles are dark red or reddish brown, and some are pale, from milky yellow to pink. Prefer to live on soft texture and place separately.
Portuguese man-of-war
The monk's hat jellyfish can predict storms, and it has a floating sac with long tentacles hanging underneath. There is a special gland inside the sac that emits carbon dioxide, causing it to expand. Jellyfish, which means "bubble" in Greek, is able to rise and decrease with the help of this "bubble", causing the jellyfish to float to a place where there is food, or away from predators. The killer weapon of the monk hat jellyfish is its tentacles, and the tiny tentacles of the monk hat jellyfish can reach a length of 9 meters, so many swimmers are too late to dodge when they see the monk hat jellyfish. The toxin secreted by the monk's hat jellyfish belongs to the neurotoxin, and over time, in addition to severe pain, the injured person will also experience a sudden drop in blood pressure, difficulty breathing, gradual loss of consciousness, general shock, and finally death due to pulmonary circulatory failure.
Monk-hat jellyfish like to live in groups, and there are traces of them from all over the world, and from the boat, the scene is very moving: transparent floating sacs drifting with the waves, blue-purple brilliance constantly flashing in the sun, long, soft tentacles like beautiful ribbons. Although its appearance is moving, many marine animals dare not approach it, because the tentacles are full of countless poisonous stinging cells, and the venom inside is as powerful as the venom of the tweezer ostrich.
Stingray rays
Stingray rays, commonly known as stingrays, are cartilaginous fish with a flattened body and an elongated tail, and some species of stingerfish have one or more serrated stingers on their tails. Its signature movement is that its wing-like pectoral fins swing in the sea, and the tail cartilage tissue is slender like a whip with stingers. There are about 480 known species of rays, and according to the 1995 Dangerous Marine Life - Wild First Aid Guide, the rays are the largest known poisonous fish, with a tail of up to 37 cm long. If it is stabbed into the chest cavity, it will cause serious injury or even death, especially if the heart is injured, it is necessary to operate urgently, but the injury to the heart is usually difficult to escape death.
