A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling.
In ants that bite instead of sting, such as the Formicinae, the bite causes the wound, but during the bite the abdomen bends forward to spray formic acid into the wound, causing additional pain. In arachnids that sting (all largely scorpions), the stinger is not a modified ovipositor, but instead a metasoma that bears a telson. [18]
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years.
A venomous spider bite (like this brown recluse bite) can cause a red or purplish rash radiating from the site of the bite. There are only a few species of spiders in the U.S. that can bite humans.
Yellowjacket sting in its sheath in the scanning electron microscope. Among arthropods, a sting or stinger is a sharp organ, often connected with a venom gland and adapted to inflict a wound by piercing, as with the caudal sting of a scorpion. Stings are usually located at the rear of the animal.
A centipede bite is an injury resulting from the action of a centipede's forcipules, stinger-like appendages that pierce the skin and inject venom into the wound. Such a wound is not strictly speaking a bite , as the forcipules are a modified first pair of legs rather than true mouthparts .

The pain of a sting from the Arizona Bark Scorpion has been compared to being struck by a bolt of lightning or electrical current. [6] These symptoms may become visible 4 to 7 minutes after injection of venom. Envenomation of a human by a scorpion may affect the sympathetic or parasympathetic systems depending on the species of scorpion.
