Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. The greatest diversity of scorpions in the Northern Hemisphere is to be found in regions between the latitudes 23 and 38°N.

The word "scorpion" is thought to have originated in Middle English between 1175 and 1225 AD from Old French "scorpion", or from Italian "scorpione", both derived from the Latin "scorpius", which is the romanization of the Greek word "σκορπίος" – skorpíos.
