1. Arizona bark scorpion: Pain can last for 72 hours.
The Arizona bark scorpion is one of the most venomous scorpions in North America, and they are quite common, especially in Arizona. A sting from one can cause intense pain, potentially leading to muscle spasms, difficulty breathing, and foaming at the mouth. While its venom is rarely fatal, the pain can last up to 72 hours, making it excruciating. They typically hide in dark places during the day and are active and hunting at night. Therefore, never move around at night, especially in desert areas.

Pain level : 8/10. The pain is intense and may last for several hours, accompanied by muscle spasms and localized numbness.
2. Black widow spider: Bites worsen rapidly.
The black widow spider is one of the most notorious spiders, especially the females, whose bites can be excruciating. Initially, it might feel like a needle prick, but quickly the bite can spread to cause severe pain throughout the body, difficulty breathing, and high blood pressure. In the most severe cases, pregnant women may even experience premature labor. The venom of this spider is extremely potent, so if bitten, seek medical attention as soon as possible.

Pain level : 9/10. It starts as a slight stinging pain, which quickly develops into severe body aches and muscle spasms.
3. Box jellyfish: Pain bursts within five minutes.
Box jellyfish are among the deadliest creatures in the ocean. Their tentacles contain venom that can cause extreme pain, difficulty breathing, and even cardiac arrest within five minutes. Surprisingly, box jellyfish are not only venomous in the water; even those washed ashore can release venom from their tentacles, posing a health risk to humans. Researchers are currently developing an antidote for box jellyfish stings, hoping to alleviate the damage quickly.

Pain level : 10/10. The stinging sensation is intense and can cause difficulty breathing and cardiac arrest within minutes.
4. Bullet Ant: The pain is unbearable.
The sting of the bullet ant is considered one of the most painful in the insect world. Entomologist Justin Schmidt experienced it firsthand and described the pain as feeling like having a 3-inch nail stuck in your heel while walking on burning charcoal. Although the ant's venom is not fatal, its sting is excruciating, with pain lasting up to 24 hours. They live in South America, hence the name "24-hour ants."

Pain level : 10/10. Intense burning and dull pain, lasting for a long time, almost unbearable.
5. Hira Venom Lizard: One bite and the pain is incredibly intense.
The Shira monster is one of the few venomous lizards. Unlike snakes, they don't inject venom through their fangs; instead, they bite their target with their sharp teeth to ensure the venom enters the body. Their bites cause intense pain, but they usually won't attack humans unless disturbed. If bitten, take immediate action to prevent the venom from spreading.

Pain level : 7/10. Severe pain at the wound site, accompanied by swelling, and the pain lasts for a long time.
6. Viper: The pain is intense; timely treatment is very important.
Vipers (such as copperhead snakes and rattlesnakes) are common venomous snakes in the United States. Although their venom is relatively mild, the pain after a bite is not to be underestimated. Within minutes of the bite, swelling begins near the wound, accompanied by intense pain, numbness, and swollen lymph nodes. While their venom is usually not fatal, without prompt treatment, it can lead to damage to surrounding tissues or other serious consequences.

Pain level : 8/10. There will be severe swelling around the wound, accompanied by persistent pain and numbness.
7. Platypus: Seemingly docile, but actually extremely venomous.
When people think of animals in Australia, they often picture the adorable platypus. But did you know that male platypuses have venomous spurs on their hind legs? These spurs serve as a defense against threats, and a sting can cause intense pain and swelling. Conventional painkillers are almost useless in relieving the pain. While they don't usually attack humans unprovoked, if you provoke them, you're in for a world of hurt.

Pain level : 8/10. Severe stinging and swelling, unresponsive to conventional painkillers.
8. Stingray: Stepping on it causes excruciating pain.
Stingrays have sharp, venomous barbs on their tails, and accidentally stepping on them can cause excruciating pain. Stingray venom can cause intense pain and may also lead to difficulty breathing, muscle spasms, and even seizures. While stingray attacks are usually not fatal, the pain can last from 6 to 48 hours if you accidentally touch them, and in severe cases, it can even be life-threatening.

Pain level : 9/10. Extremely intense stinging sensation, accompanied by symptoms such as muscle spasms and bleeding.
9. Stonefish: Master of disguise, deadly stinger.
Stonefish are among the most venomous fish in the world. They are extremely adept at camouflage, typically hiding on the seabed or in coral reefs. A sting from their venomous spines can cause intense pain, possible shock, and even death. Stonefish have venomous spines on their dorsal fin; if stung, immediate medical attention and treatment with antivenom are necessary. Otherwise, it may lead to cardiac arrhythmia or temporary paralysis.

Pain level : 10/10. Extremely severe pain, accompanied by possible shock and death.
10. Tarantula wasp: The sting lasts only five minutes, but the pain is unbearable.
Tarantula wasps are insects that prey on tarantulas, and their stings are among the most painful in the insect world. According to the Schmidt Sting Pain Index, tarantula wasp stings rank second in pain. Although the pain only lasts for five minutes, during that time you will experience extreme, intense pain. Fortunately, the pain gradually subsides over time, but five minutes of excruciating agony is still enough to make it unbearable.

Pain level : 9/10. Although the pain lasts for a short time, the intensity of the pain is almost unbearable.
From Arizona bark scorpions to tarantula wasps, the stings and bites of these animals can be excruciating. If you accidentally encounter these creatures, remember to stay calm and try to avoid being bitten or stung. In the event of an accident, seeking medical attention immediately is the best way to minimize harm!
