The inland taipan is one of the most venomous snakes, according to the International Journal of Neuropharmacology, meaning just a teensy bit of its venom can kill prey (or human victims). They live tucked away in the clay crevices of Queensland and South Australia's floodplains, often within the pre-dug burrows of other animals. Living in more remote locations than the coastal taipan, the inland taipan rarely comes into contact with humans, the Australian Museum reported. When the taipan does feel threatened, the snake coils its body into a tight S-shape before darting out in one quick bite or multiple bites. A main ingredient of this venom, which sets it apart from other species, is the hyaluronidase enzyme. According to a 2020 issue of Toxins journal ( Read More »
You could be bitten multiple times before becoming aware of the coastal taipan (Oxyuranus scutellatus), thanks to its incredible speed, according to the Australian Museum. When threatened, this snake, which lives in the wet forests of temperate and tropical coastal regions, will lift its whole body off the ground as it jumps fangs-first with extraordinary precision and injects venom into its enemy. Before 1956, when an effective antivenom was produced, this snake's bite was nearly always fatal, according to Australian Geographic. The snake's venom contains neurotoxins, which prevent nerve transmission. Read More »
The king cobra (Ophiophagus hannah) is the world's longest venomous snake, measuring up to 18 feet (5.4 m), according to the Natural History Museum in London. The snake's impressive eyesight allows it to spot a moving person from nearly 330 feet (100 m) away, according to the Smithsonian Institution. When threatened, a king cobra will use special ribs and muscles in its neck to flare out its "hood" or the skin around its head; these snakes can also lift their heads off the ground about a third of their body length, according to the San Diego Zoo. Its claim to fame is not so much the potency of its venom, but rather the amount injected into victims: Each bite delivers about 7 milliliters (about 0.24 fluid ounces) of venom, and the snake tends to attack with three or four bites in quick Read More »
The banded krait (Bungarus fasciatus) is a slow mover during the day and is much more likely to bite after dark. The snake's venom can paralyze muscles and prevent the diaphragm from moving, according to a 2016 study published in the journal PLOS Neglected Tropical Diseases. This stops air from entering the lungs, effectively resulting in suffocation
The saw-scaled viper (Echis carinatus) is the smallest member of the "Big Four" in India — along with Russell's viper, the common krait (Bungarus caeruleus) and the Indian cobra (Naja naja) — thought to be responsible for the most bites and related deaths in the country. Along with their fellow vipers, the Russel's viper and the pit viper, these nondescript little reptiles may be responsible for about 58,000 deaths a year in India alone.
It's hard to get accurate estimates, as many people who are bitten by snakes live in regions with poor medical care and never report their encounters with the deadly reptiles. But around 58,000 deaths in India are attributed to snake bites every year, and the Russell's viper (Daboia russelii) is responsible for the majority of these mortalities, according to research published March 25, 2021, in the journal PLOS Neglected Tropical Diseases. This species is considered one of the most deadly of the true vipers, researchers reported in 2021 in the journal Toxins.
About 24 hours after being bitten on the thumb by a juvenile boomslang (also called a South African green tree snake), herpetologist Karl Patterson Schmidt died from internal bleeding from his eyes, lungs, kidneys, heart and brain, researchers reported in 2017 in the journal Biochimica et Biophysica Acta. The snake had been sent to Schmidt at The Field Museum in Chicago for identification. Like others in the field at the time (1890), Schmidt believed that rear-fanged snakes like the boomslang (Dispholidus typus) couldn't produce a venom dose big enough to be fatal to humans. They were wrong. Read More »
A bite from a fer-de-lance (Bothrops asper) can turn a person's body tissue black as it begins to die, according to a 1984 paper published in the journal Toxicon. These pit vipers, which live in Central and South America and are between 3.9 and 8.2 feet (1.2 and 2.5 m) long and weigh up to 13 pounds (6 kg), are responsible for about half of all snakebite venom poisonings in Central America, according to a 2001 study published in the journal Toxicon.
Black mambas are some of the scariest snakes on the planet. Named for the dark, inky color inside of their mouths, black mambas are actually brownish in color. They average around 8 feet (2.5 meters) in length.Fast and deadly, these blue-tinged snakes are thought to be responsible for up to 20,000 deaths a year, though precise numbers are hard to come by.
Eastern brown snakes are endemic to eastern Australia and are responsible for more human fatalities than any other snake species in the country. Their venom is highly potent, containing powerful toxins that can cause paralysis and internal bleeding. The initial bite is often painless, according to the Australian Museum.
"They're the only snakes in the world that regularly kill people in under 15 minutes," Bryan Fry, who studies venom at the University of Queensland, told ABC News in 2024. "Even more insidiously than that is that for the first 13 minutes, you're going to feel fine." Read More »
Common death adders are found across coastal areas of southern, eastern and northern Australia. They are recognizable thanks to their broad, triangular heads, short, thick bodies and thin tails. Common death adders are ambush predators and wait for prey — including frogs, lizards and birds — under leaves until they are ready to strike.
Bites to humans are rare and normally involve a person stepping on one by accident. Their venom causes paralysis and can lead to death: Before the introduction of antivenom in the 1950s, about 60% of bites were fatal, according to the Australian Museum Read More »
13. Eastern diamondback rattlesnake
Eastern diamondback rattlesnakes (Crotalus adamanteus) are the largest rattlesnakes in the U.S. and are found across southeastern states, including Florida, North Carolina, South Carolina, Alabama, Georgia, Mississippi and Louisiana.
They are ambush predators and tend to lie quietly coiled away waiting for prey to approach. They can strike a victim up to two-thirds of their body length away, injecting a large quantity of venom with each bite. The species is not aggressive to humans, and bites tend to occur if a snake is intentionally harassed or accidentally stepped on, according to the Florida Museum. Read More »
