Scorpion sting Wikipedia
Scorpion stings are a cutaneous condition caused by the stinging of scorpions, usually resulting in pain, paresthesia, and variable swelling. The anatomical part of the scorpion that delivers the sting is called a "telson".
Most scorpion stings vary from small swelling to medically significant lesions in severity, with only a few able to cause severe allergic, neurotic or necrotic reactions. Only two species of scorpions can inflict stings which result in death of normal healthy humans: the Israeli deathstalker (Leiurus quinquestriatus) and the Brazilian yellow scorpion (Tityus serrulatus). Antivenom exists for both species' stings.
