Scorpions are known for their sting, which injects poison into their prey and is used to immobilize them. All scorpions are poisonous, but only a small number can be harmful to humans.
There are approximately 25 species of scorpion that will cause harm to humans. Some scorpions can be fatal, so it?s important to know the types of scorpions and what they look like so you can avoid them. Typically, though, most scorpions are not aggressive, and they will only sting when provoked or threatened.
The deadliest scorpion in North America is the bark scorpion. These scorpions are found mostly in Arizona and Mexico, but they have spread to other areas of the southwestern United States. The bark scorpion is a member of the Buthidae family of scorpions, which are the most dangerous to humans. This is also the largest family of scorpions. Other members of this family include the fat-tail scorpion and the deathstalker.
Scorpion venom is made up of a combination of neurotoxins and enzyme inhibitors. The combination and the amount used is regulated when the scorpion stings. The effect of the venom is different on each type of prey the scorpion hunts. The venom is very fast acting, and it can also be used as a defense mechanism against predators.
Most scorpions that are poisonous to humans are found in Asia and Africa. These scorpions have larger tails and smaller pedipalps, or pincers, than other species. The large tails are strong and can emit a powerful sting. Scorpion stings are rarely fatal. The people most susceptible are the elderly, children and people with compromised immune systems.
Scorpion venom is also studied for its medicinal use. Research is currently being done on the toxins in scorpion venom to help with the treatment of a number of autoimmune disorders, such as multiple sclerosis. The venom is also being studied for its effect on several types of cancers.
