Did you know that there are more than 3,000 species of snakes on Earth? Of these, about 600 are toxic. Even fewer poisonous snakes are unbelievably venomous. The most venomous snakes are usually ranked using the LD50 scale, LD means "lethal dose", the LD50 value is the dose of venom, the dose that can kill half of the overall harmful substance of the test, usually venom is tested on mice, the lower the number, the greater the poison of the snake. However, what are the most venomous snakes in the world and what makes them so dangerous?
12. Spearhead
LD50: 3 mg
Average injection of venom per mouth: 500-1500 mg
The spearhead snake is responsible for most deaths from snake bites and is one of the most venomous snakes in the world. Located in South and Central America, as well as Mexico and Brazil, the spearhead snake is one of the most dangerous venomous snakes there. Adult snakes are 240 cm long and weigh an average of 4-6 kg and are found in many densely populated areas.
Depending on the species, spearhead snake bites contain an average of 500-1500 mg of venom. Knowing that it takes 3 mg to kill a mouse, you can only imagine that this snake is just as dangerous for humans - it can kill an average of 6 people in one bite! This snake is not the most venomous snake in the world, but it is very dangerous!
11. King Cobra
LD50: 1.9 mg
Average injection of venom per mouth: 400-1000 mg
The king cobra is one of the most venomous snakes in the world, and for good reason. Not only does it inject an average of 400-1000 mg per mouthful, but its venom is enough to kill about 11 people in one bite! The king cobra is located in South Asia and can reach a length of 3-4 meters, which is much longer than any other venomous snake.
Studies have shown that given the high levels of neurotoxins and cytotoxins, a bite by a king cobra can be life-threatening in as little as 30 minutes. Also, given the length of this particular snake, it usually bites higher on the body.
10. Black Mamba
LD50: 0.3 mg
Average injection of venom per mouth: 100-400 mg
Probably heard of the dangerous nature and terrible reputation of the Black Mamba. The Black Mamba is located in sub-Saharan Africa and not only has a bite force comparable to any other snake, but is also very large. It is the largest venomous snake in Africa, usually reaching a height of 3 meters. In addition, it can lift its body into the air like a cobra, and often bites more than once, quickly taking a bite before running away, at speeds of up to 20 kilometers per hour!
This snake has an extremely deadly venom in its fangs, and although it can inject 100-400 mg of venom in one bite, the average person will die within 6-14 hours of being bitten. In fact, most symptoms appear in as little as ten minutes. Black mamba bites also have analgesic effects, which make their victims feel as if they hadn't been bitten, or maybe the bite wasn't as bad as it actually was. This is truly one of the most dangerous and venomous snakes in the world.
9. Forest cobra
LD50: 0.22 mg
Average injection of venom per mouth: 570-1100 mg
The king cobra has a cousin who is capable enough to bite a person to death in one bite. In fact, the forest cobra's bite force and venom production are enough to kill 65 adults in one bite! This is both because of its low LD50 score of 0.22 and because of its ability to inject large amounts of venom. With an average of 570 mg per bite and up to 1100 mg, the forest cobra is as virulent as a large number of venomous snakes.
Forest cobras located in Africa are highly adaptable in terms of their diet and behavior. He does not have frequent contact with humans and prefers to live in isolation in forests, rivers and grasslands. However, if you happen to be bitten by a forest cobra, you may experience severe symptoms in as little as 30 minutes. Organ failure and paralysis, as well as lethargy, are common, so immediate medical attention is key.
8. Rousssell's viper
LD50: 0.16 mg
Average injection of venom per mouth: 130-250 mg
The Rousssell's viper is highly venomous, with a mortality rate of about 2.6% in India, and considering that 40-70 mg of Russell venom is enough to kill the average person, the bite of this snake is especially dangerous! In fact, more people are killed in Sri Lanka, Myanmar and India than any other snake. This snake is found in the open steppes of the Indian subcontinent and is found in densely populated areas.
Local swelling and bleeding are common when bitten by a venomous snake, and the venom of this venomous snake may have adverse side effects for up to two weeks, depending on the severity.

Injection: 35-180 mg
Tiger snakes are a variety of genera of snakes, from the Chaper Island tiger snake to the black tiger snake, common tiger snake, western tiger snake, eastern tiger snake and continental tiger snake, these are the most venomous snakes on the entire planet, they inhabit Australia and its coastal land.

6. African tree snake
LD50: 0.1 mg
Average injection of venom per mouth: 1-8 mg
The African tree snake lives in trees in most parts of Africa, especially in Eswatini, Botswana, Namibia, Mozambique, and Zimbabwe. There is no doubt that the bite force is very strong, only 1-8 mg can be injected at a time. However, it has a low LD50 amount and can kill a person with a single bite. But what could be more dangerous than this venom? People develop a false sense of security after being bitten.
This African tree snake is notorious for biting, and many victims of African tree snake bites believe they were bitten by dry bites or non-lethal doses.

Among the taipan snake species, the coastal taipan snake is one of the most venomous snakes in Australia. While the name may imply that this snake only lives near the ocean, the coastal taipan snake is found throughout Australia and can kill up to 56 people in one bite! Considering that this snake has an extremely low LD50 value, it also injects a relatively small amount of venom compared to other venomous snakes.
