There are a few snakes on the planet that may cause major damage or death to humans. Although the vast majority of snakes on the planet are quite innocuous (inflicting only minor flesh wounds), a tiny number of species are extremely deadly to humans owing to their aggressive nature and strong venom.
There is a distinction to be made between dangerous and lethal snakes. Dangerous snakes are those that kill the most people each year, whereas the most venomous snake is one with the most lethal venom.
1. Inland Taipan (Oxyuranus microlepidotus)
The Taipan snake is an extremely poisonous snake native to Australasia. It is a member of the elapid family (which includes cobras) and is regarded as one of the world’s deadliest snakes. The Taipan is divided into three species: Coastal Taipan, Inland Taipan, and Central Ranges Taipan.
However, Inland Taipan take’s the cake as, it has the most toxic venom of its species. Maximum yield recorded (for one bite) is 110mg. That would probably be enough to kill over 100 people or 250,000 mice.
2. Eastern Brown Snake (Pseudonaja Textilis)
Eastern Browns may be found throughout throughout Australia, with the exception of deep woodlands. They are particularly frequent near farms since their main target is the common house mouse. This incredibly lethal snake has a slender look and may grow to a length of 4.9 to 6.6 feet.
The Eastern Brown, as the name says, is generally brown in color, with certain snakes taking on a blackish look as well. Eastern Browns are distinguished by their short fangs, dark tongues, and dark black eyes. They are also extremely lonely and prefer to be active during the day. It is a very dangerous snake, with an LD 50 of 0.001 mg/kg.
The venom of the Eastern Brown Snake is extremely hemotoxic. Their poison assaults the blood immediately and prevents it from clotting. Bites can cause internal bleeding, renal damage, and, in rare cases, neurotoxic paralysis. These snakes utilize their venom to kill mammals, reptiles, birds, and amphibians in a matter of seconds.
3. Malayan Blue Krait (Bungarus Candidus)
The Blue Krait, often known as the Malayan Krait, is an extremely poisonous elapid snake. The snake grows to be around 3.6 feet long on average and has a color pattern of bluish-black crossbands divided by yellowish-white interspaces. The Blue Krait is mostly found in Southeast Asia. It typically consumes mice, other snakes (particularly Blue Kraits), reptiles, and rodents.
Even with medical care, almost 50% of Blue Krait bites are deadly. Blue Kraits’ venom contains incredibly strong neurotoxins. This results in paralysis, and death is frequently caused by respiratory failure.
4. Mainland Tigersnake (Notechis Scutatus)
The Mainland Tigersnake is a highly poisonous snake found in Australia and Tasmania’s southern regions. Because of the availability of food in these conditions, the snake is commonly found in coastal areas, wetlands, and marshes. Tigersnakes grow to be around 3.93 feet long and come in a wide range of colors (olive, yellow, orange, brown, and black) depending on where they live.
The venom of mainland Tigersnakes affects the neurological system, blood clotting proteins, and muscles. This venom is extremely lethal to amphibians, mammals, birds, and reptiles. When attacked, Tigersnakes flatten their neck, forming a hood similar to that of a cobra.
5. Beaked Sea Snake (Hydrophis Schistosus)
The Beaked Marine Snake is one of the world’s most poisonous sea snakes. These snakes are notoriously violent and are frequently encountered in fishing nets. Fishermen are regularly bitten while attempting to disentangle them. The downward-pointed scales on the tip of its snout give Beaked Sea Snakes its name. It resembles a bird’s beak.
The Beaked species, like many sea snakes, has a flattened, paddle-like tail that helps it navigate ocean waters. Among marine snakes, they are responsible for the most snakebites. Beaked Sea Snake bites frequently result in paralysis and muscular damage. The venom of these snakes is very neurotoxic and hemotoxic.
6. Saw Scaled Viper (Echis Carinatus)
The Saw-Scaled Viper is not the most poisonous snake in the world, but it is one of the most dangerous. The Saw-Scaled Viper is a tiny, irritable, and aggressive snake. Saw-Scaled Vipers are a major source of snakebite injuries in India because to their disposition. Saw-Scaled Vipers are brown, tan, or mahogany mosaics.
They frequently hide in the sand with only their heads showing, making them difficult to find. When you approach one, it will produce a loud rasping sound by rubbing its scales together.
Their venom is similar to that of many other vipers in that it contains toxins that interfere with blood coagulation and kill tissue. Bites can be fatal and should be treated as quickly as possible with anti-venom. They use their venom to hunt small mammals, amphibians, arthropods, reptiles and small snakes.
7. Eastern Coral Snake (Micrurus fulvius)
The coral preys mostly on reptiles, especially other snakes, and may be found in the United States’ southeastern and Gulf shores. It is one of the few terrestrial poisonous snakes in the United States with fixed, hollow fangs, and it is even less violent than the copperhead, making it America’s least aggressive poisonous snake.
It’s also a good example of Batesian mimicry, an evolutionary strategy: To defend itself from predators that have evolved to avoid red and yellow snakes, a harmless mimic (in this example, many species of milk snakes) takes on the physical appearance of a noxious model (the eastern coral snake). Coral Snakes have a very potent venom but many are too small to deliver enough venom to kill a human.
8. Boomslang (Dispholidus Typus)
The most deadly snake in the Colubrid family is the Boomslang. When feasible, these snakes will avoid confrontation. Boomslangs are tree-dwelling snakes that are extremely vigilant. These snakes feature keeled scales in a variety of patterns and hues such as black, grey, brown, and green. Boomslangs are capable of causing human deaths and have even killed people in the past.
They have very long fangs and can open their mouths a full 180 degrees to bite. However, because to their rear-positioned teeth, they have a more difficult time injecting venom than the other venomous species on this list. They consume birds and lizards (mainly chameleons), which they seize and hold onto till their poison takes effect.
9. Death Adder (Acanthophis Antarcticus)
The Common Death Adder is one of Australia’s most unusual snakes. Because they reside so near to people and pets, Death Adders are a hazardous species of snake. These small and stocky snakes have the appearance of vipers, yet there are no vipers in Australia. They usually have bronze, orange, or brown bands across their bodies.
Ambush predators, Death Adders are. They employ a hunting strategy known as caudal luring, in which they use their tails as a ‘lure’ to imitate a worm. When an unwary lizard, frog, or mammal gets too close, the Death Adder attacks. They are among the world’s quickest striking snakes. A dose of 10mg Death Adder venom is sufficient to kill a human. A good sized Death Adder can deliver up to 180mg in a single bite.
10. Russell’s Viper (Daboia Russelii)
Rodents are a key food source for the Chain Viper. As a result, because rats and mice like to be close to humans, these snakes are frequently seen around human settlements.
Chain Vipers have triangular heads with rounded (and elevated) snouts. Their color patterns vary from snake to snake, but they are commonly yellow, tan, and brown. These deadly snakes can reach lengths of 5.5 feet, with a width of approximately six inches.
Chain Vipers’ bites contain a significant quantity of venom, which is very fatal to humans in amounts of 40–70 mg. Excessive bleeding (especially in the gums and urine), a quick drop in blood pressure (and pulse rate), blistering, necrosis, vomiting, facial swelling, renal failure, and blood clotting are all common signs of a Chain Viper bite.
