1. Box jellyfish: Tops the list most venomous animals
Up to this point, box jellyfish are animals with the strongest venom known to humans. They live mainly in the Pacific and Indian Oceans. Every year, they take the lives of hundreds of people. They have 15 tentacles 3 meters long with 5,000 microscopic needles on each tentacle, which will cause those who touch them to die. Their poison will attack the heart, nervous system and skin cells very quickly. That’s why this box jellyfish is also considered the “invisible killer” of the ocean.
Box jellyfish have long been famous for possessing the world’s strongest venom, enough to terrify and kill enemies instantly. Therefore, their prey such as fish, shrimp or other marine creatures have almost no chance to escape from those soft but no less dangerous tentacles.
Their venom is considered one of the most dangerous in the world, containing toxins that can attack the heart, nervous system and skin cells. It causes extremely terrible pain, victims will go into shock, drown or die of heart failure before they can reach shore. If they are lucky enough to survive, victims can still experience persistent pain for weeks and are often “honoured” to have scars on their bodies – where their tentacles come into contact. .
2. King Cobra
King cobras are considered dangerous and scary within their range, although this snake does not actively attack humans. The king cobra is revered in many different cultural beliefs, especially in the Hindu culture of the Indian subcontinent.
Depending on the living environment, the king cobra’s skin has different colors. Normally, snakes that live in places with lots of light, rivers, streams, and lakes have light-colored skin. Snakes that live in places with little light, deep forests, high mountains, and caves have dark skin. The skin on the head and back varies in color according to the habitat, ranging from lead black, tan, olive brown to gray brown, gray white. Faint white or yellow lines run along the length of the body. The abdomen is cream or pale yellow, with smooth scales. The neck is bright yellow or cream.
They have a length of up to 5.5 m and are the longest venomous snake in the world. King cobras live mainly in forests in Asia. According to scientists, each bite of a king cobra carries an amount of poison that can kill an African elephant within a few hours and cause death to 20 adults . They are normally very gentle and stay away from places where humans live, but if we violate their territory, the king cobra will not hesitate to stand up 1.8 m and attack us suddenly.
3. Blue-Ringed Octopus: One of the Most Venomous Animals in the Ocean
Continuing the list of 10 most venomous animals is the blue-ringed octopus.
The blue-ringed octopus lives mainly in the Pacific Ocean. Their bodies are small with a diameter of about 20 cm and beautiful colors, but they are the most dangerous species on the planet. With only 25g of blue-ringed octopus venom, it can paralyze the entire body of 10 people and they have two extremely powerful venoms used for defense and hunting. It is very difficult for humans to detect if bitten by them because their bite is not painful. Just a few minutes after the bite, the victim will feel paralyzed, nauseous, have difficulty swallowing and can die if not treated promptly.
Carrying the neurotoxin tetrodotoxin (TTX) in the salivary glands, the blue-ringed octopus is a real threat to humans, especially fishermen who use their bare hands to handle seafood every day. TTX is a powerful neurotoxin that, when entering the bloodstream, will block the movement of sodium ions in nerve cells. Usually, after being bitten by this octopus, symptoms of poisoning will appear about 1 to 5 minutes. In addition, people can be poisoned by mistaking blue-ringed octopuses for regular octopuses, so they should be used to prepare dishes. In case of gastrointestinal poisoning, poisoning symptoms may begin 10 to 20 minutes after eating.
4. Stone Fish
Fighting fish are also known as devil-faced fish and live mainly in the Pacific and Indian Oceans. Dubbed the “king of venom in the ocean”, the devil-faced fish is one of the most poisonous fish in the world that does not directly attack the enemy but can kill an adult in just 2 hours with its His thorn is filled with venom. The devil-faced fish impresses with its rough body, rough, patchy skin all over in reddish brown and moss color with many sharp fins on the spine. At first glance, they have a rock-like shape, making it easy to hide under sand or camouflage on rocks to hide from enemies.
When a fighting fish’s fins hit a human (usually caught by a hand or stepped on by a foot), the fin rays will immediately penetrate 1cm deep into the victim’s flesh. At that time, toxins from under the spines will be sprayed into the air along the rays. vertically, inside the human body, directly affecting the motor system, nervous system and causing the smooth muscle of the human heart to swell, disrupting blood pressure, heart rate, and breathing. Mild cases cause the victim to feel intense pain lasting up to 12 hours, accompanied by symptoms such as nausea, tremors, abnormal heart rhythm, convulsions and paralysis. In severe cases, death will occur within 2 hours.
5. Death Stalker Scorpion
Death Stalker is the scorpion species that is considered to have the strongest venom of all scorpions present on this earth. The bitten person will suffer terrible pain, followed by respiratory failure, cardiac arrhythmia…
Up to this point, the Death Stalker is the scorpion with the strongest venom of all scorpions living in the world. They are pale yellow and live mainly in the Middle East and North Africa. This species’ venom contains a lot of neotrotoxin – a toxin that causes central nervous system disorders, directly affecting the brain as well as the respiratory and cardiovascular organs. When bitten by this species, the victim will suffer terrible pain and may die if not treated promptly.
6. Pufferfish family
The pufferfish family is a vertebrate species that possesses the second most terrifying venom in the world, just behind the yellow poison dart frog. They live mainly in the waters of China, Japan, Mexico and the Philippines. In their liver, kidneys, and sometimes even their skin, they contain a powerful neurotoxin called tetrodotoxin. However, in Japan and some other countries, this puffer fish is popular and considered as a specialty.
Specifically, pufferfish venom is 1,200 times stronger than cyanide (an extremely toxic substance that requires only 50mg – 200mg of cyanide or inhalation of 0.2% cyanide gas to cause an adult to die immediately). The venom of a pufferfish can kill 30 adult men in just 20 minutes to 24 hours, no less than the venom of a king cobra.
7. Poison Dart Frog
The yellow poison dart frog is a very deceptive creature – despite being only 55mm in size, it is the most venomous creature on Earth. Just one amphibian contains enough venom to kill more than 10 adult men within 3 minutes. The name of this species comes from the indigenous hunters of Emberá in Colombia, who used frogs to make deadly darts.
The bright yellow frogs live only in small tropical forests on Colombia’s Pacific coast, and their color can sometimes vary between yellow, orange, or pale green. Its visual allure is intentional, a tactic called repelling signals or warning colors to ward off potential predators. A 2001 study by Kyle Summers of East Carolina University in Greenville found that the brightest colored frogs are always the most unique.
Mere contact with a yellow poison dart frog is not fatal, as amphibians only produce and excrete powerful toxins through their skin when it feels threatened. But holding it in your hand for a few seconds without wearing gloves is suicidal. The frog’s skin is quickly covered with an alkaloid poison (batrachotoxin) that has the ability to “freeze” the nerves, preventing them from transmitting impulses. Within minutes, the victim experiences uncontrollable muscle contractions and eventually heart failure.
8. Inland Taipan Snake: Among the Most Venomous Animals in the World
The Taipan is the most venomous snake of any land snake on Earth, also known as the “fierce snake”. So it’s no surprise that it is on the list of Top 10 most venomous animals.
This 2.5 meter long snake is found in inland areas in Australia such as Queensland, South Australia, New South Wales and the Northern Territory. This is also considered the most venomous snake in the world because the toxin in its venom can kill 100 people. They are 200 times more dangerous than regular cobras, but they are very shy and stay away from places where humans live. Therefore, there are currently no statistics showing that any human has lost their life because of this snake.
In addition to possessing the most terrible biological venom on land, the Inland Taipan also has the ability to change the color of its skin according to the season. It can change from dark brown to dark olive green or dark green. Research by scientists shows that the inland Taipan has venom that is 50 times more toxic than a common cobra and 10 times more toxic than a Mojave rattlesnake. With only an amount of venom equal to 110mg, the Inland Taipan can cause 100 people to die in 45 minutes without timely medical intervention.
9. Cone Snail
Cone Snail , also known as cone snail, mortar snail, has a mainly cone-shaped appearance and the largest one can be up to 23 cm long. They are completely carnivores and predators, their main food is fish, marine worms, small fish, mollusks and even other cone snails. It can secrete venom at any time in its life, and this species is always ready to wipe out all living things around it.
This species is extremely toxic, preferring to hide in coral reefs, rocks and sandy sea bottoms from intertidal to subtidal zones in southeast China and tropical seas. Their bodies contain more than 200 pharmacologically active substances and one drop of venom can kill 20 adults. To date, there have been at least 100 recorded deaths caused by this species’ venom and in reality this number could be much larger.
Their venom is made up of a mixture called conus peptides. Each of them will have a unique venom structure. More than 50,000 conus peptides have been discovered, they are all neurotoxins and no vertebrate species on our planet possesses this form of venom.
10. Banana spider (Phoneutria nigriventer)
Banana spider (Phoneutria nigriventer) is a wandering spider in the Ctenidae family, the most venomous spider in the world. This spider has strong venom and is very aggressive. People also call them banana spiders because they have been found mainly in areas where banana trees thrive. This spider’s venom causes side effects such as severe pain, muscle paralysis or difficulty breathing. It can even cause lack of oxygen leading to death. However, the death rate is not too high, out of 7,000 people bitten by this spider, only 10 people died.
Banana spider venom is a complex compound of toxins, peptides and proteins that affect ion channels and chemical receptors in the victim’s body neuromuscular systems. One of the toxic fractions, designated PhTx-3, has six neurotoxic peptides (Tx3-1 to Tx3-6).
Testing has shown that Phtx3 and one of the peptides called Tx3-3 act as calcium channel blockers by reducing the amount of calcium that contributes to glutamate3 and acetylcholine2 release in the cerebral cortex and synapses. Simply put, the venom of banana spiders disrupts brain function and wreaks havoc on it.
11. Black mamba snake
Continuing the list of 10 most venomous animals is Black mamba snake.
The black mamba (Dendroaspis polylepis) is a venomous snake endemic to sub-Saharan Africa. The common name of this species does not come from the color of the snake’s scales, but from the inky black color inside the snake’s mouth. This is the longest venomous snake on the African continent, with a typical length ranging from 2m to 3m and up to 4.3 – 4.5m. This species is one of the fastest moving snakes in the world, capable of moving at speeds of 11 km/h over short distances.
The black mamba’s venom is highly toxic, capable of causing unconsciousness in humans within 45 minutes or less. Without effective antivenom for treatment, death usually occurs within about 7-15 hours. Venom mainly belongs to the neurotoxin group, especially containing dendrotoxin. Black mambas are capable of attacking at considerable range and can sometimes deliver a series of bites in rapid succession. Despite their reputation for being very aggressive, like most other snakes, they usually try to hide from humans unless threatened or cornered.
Each of the animals mentioned above contains very strong toxins, so please research carefully and be careful when you see them. Hope “The 10 most venomous animals You Need to Know About” article will be useful to you.
