Snakes might be legless, clawless, and often toothless, but this has not stopped them from being the most dangerous and spookiest animals on Earth. The most dangerous snakes have bites that can kill a person unbelievably fast. What is it about their venom that makes it such a big threat?
You see, snake venom is basically saliva with a number of zootoxins. Some of them can damage the nervous system and cause paralysis. There are others that kill cells, which leads to horrifying gangrene, injuries, and amputation. Aside from these, there are toxins that lead to uncontrollable bleeding and cause blood clots in the body. If that is not enough for you, they are also very painful. These are only a couple of traits possessed by the most dangerous snakes on the planet. Keep reading to find out which one can grow as long as 19 feet or can aim at you from 23 feet away. Mind you, some of these dangerous snakes were even worshipped as gods in some cultures.
There is an old joke going around about how every animal found in Australia wants to kill you. The Common or Coastal Taipan might be one of the reasons for this. It lives in New Guinea and Australia. Its venom comes with neurotoxin so potent that it can kill a victim in only half an hour after the bite. If you ever get bitten by it, we just hope that you will be able to go to the hospital right away.
A lot of people are worried about getting bitten by one of these snakes, but there are some that you should not be anywhere near to at all. The Philippine Cobra has a highly toxic venom that it can spit from up to 3 meters or around 10 feet away. The snake hides in waterways and ponds in fields, farms, and forests in the Philippines.
The Black Mamba has a rather big subculture popularity because it was made popular by Kill Bill and Kobe Bryant of the NBA. You should know that it is one of the most venomous snakes on the planet. An adult one has enough venom to cause the deaths of 10 people. On top of that, it always bites more than once. This is the reason the victim normally has less than a half-hour to get treated. Black Mambas can be found in the forests of eastern and southern Africa.
Eastern Diamondback Rattlesnake
The Eastern Diamondback Rattlesnake is the biggest venomous snake in North America. It can grow as long as 8 feet and boasts of a distinctive black, tan, and grey diamond pattern along the body of this reptile. The good news here is that it is not aggressive and only bites when it is provoked. If you do get bitten, know that it will cause a lot of pain, bleeding, and even death if it is not treated.
Are you wondering if the snake in the photo is truly eating a crocodile or alligator? If so, you are on the right track. Let us give you a second to take that in. The Burmese python is considered the second biggest snake on the planet in terms of both weight and size. It can reach a length of seven and a half feet up to 19 feet and weigh as much as 400 pounds. They are also nonvenomous constrictors, which means that they can just squeeze a victim to its death.
Western Diamondback Rattlesnake
For a lot of people, you are not in the American Southwest until you encounter a Western Diamondback Rattlesnake. The snake is more tan and smaller than its eastern counterpart, so it can blend in with the scrub and sand. It has significantly big venom glands and unique fangs that allow it to deliver a huge dose of venom when it bites. It is also not aggressive in general, so you better not provoke it!
A lot of venomous snakes are not that big and only rely on venom to stun prey instead of trying to crush the victim underneath its body. Despite this, here is one exception to that rule. The King Cobra can grow up to 13 feet and weigh as much as 30 pounds. The longest one ever documented was 19 feet long. Like the other cobras of Southeast Asia and India, it has a venom deadly enough to cause death in an elephant.

Its venom is a strong hemotoxin that will cause various neural disorders such as paralysis and memory loss.
This is a photo of a reticulated python all coiled up. It is thought to be the longest snake on the planet! We already checked out anacondas earlier, which is the biggest in terms of both weight and length. Even though the reticulated python is generally less heavy than the anaconda, it does grow even longer. There have reported sightings that these creatures can go up to 33 feet long! As typical of all pythons, it is also a nonvenomous constrictor. There are also cases in which it has killed humans, so beware.
Eastern Brown Snake
Do you know where you will see the second most venomous snake on the planet? The answer to that is Australia! When you are hiking in the east of Australia, you should watch your step. The snake has a highly neurotoxic venom that can coagulate the blood. The bite will cause renal failure, heart attack, paralysis, and loss of consciousness. The nasty mix of neurotoxins it carries is the reason it accounts for 60% of snakebite deaths in the land down under.
The anaconda is not venomous, unlike the other entries here. However, that does not make them any less dangerous than the others. Even though it does not normally attack humans, there are cases of anacondas eating people. There are four species of anaconda known, the biggest of which would be the green anaconda. It is even considered the biggest snake known to man! This snake can grow as long as 29 feet and weigh as much as 500 pounds. It does not kill using its venom.

This animal might be non-aggressive, but it waits to deliver the max dose of venom.
City-dwellers across Southeast Asia and India live in fear of this snake. Why is that? Russell’s Viper is a venomous creature that can grow as long as 6 feet. It mostly feeds on rodents. Its hunger for tiny mammals brings it to urban areas. It accounts for a huge percentage of snakebite deaths in the area.
A Chinese Cobra on its own is already deadly enough, so can you imagine two snakes together? In 2015, this species made the headlines when a two-headed one was born to a snake breeder based in Yulin, China. In 2009, there were reports of the birth of a two-headed member of the species as well. The highly venomous snake can be found in Taiwan and mainland China.

It is found in grasslands, woodlands, deserts, and scrubs in Australia, save for Tasmania and Victoria.
Sharp-Nosed Pit Viper
It is possible that this Southeast Asian viper species led to the birth of the “hundred pace poison” legend. It has very deadly hemotoxic venom that can cause ulcers, tissue necrosis, and hemorrhaging. According to old legends, a victim will only be able to walk a hundred paces before it dies. There are areas in which that figure drops down to only 50 paces. There is now an anti-venom, but will it reach the victim in only 100 steps?
In terms of the most deadly venom a snake can have, the Inland Taipan comes out on top each and every time. With a mix of taipoxin and neurotoxin, a bite can make the blood hemorrhage, cause limited breathing, paralysis, and serious muscle damage.

Firstly, there are three kinds of green mambas in the world – clearly, one wasn’t enough. Green mambas – Western, Eastern, and Jameson, are incredibly venomous, highly aggressive, and very unpredictable. All three species are also lightning-quick, agile, and arboreal. On top of all that, their venom is rapid-acting and the dendrotoxins are much more devastating to the central nervous system, leading to severe neurotoxicity.
The Forest Cobra, aka the black cobra, aka the white-lipped cobra is native to Africa and is the largest true cobra species. Including the tail, it grows up to 10 feet long. Yikes. As we all know, cobras can be quite lethal, so let’s just hope we never run into one.
