Scorpions are predatory arthropod animals of the order Scorpions within the class Arachnid. They have eight legs and are easily recognized by the pair of grasping claws and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm to 21 cm.

Scorpions are found widely distributed over all continents, except Antarctica, in a variety of terrestrial habitats except the high latitude tundra. Scorpions number about 1,752 described species, with 13 extant families recognized to date. The taxonomy has undergone changes and is likely to change further, as a number of genetic studies are bringing forth new information.

Scorpion venom has a fearsome reputation, and about 25 species are known to have venom capable of killing a human being.

There are thirteen families and about 1,400 described species and subspecies of scorpions. Death Stalker Scorpion is the most poisonous among the family. Also known as Yellow Palestine scorpion is found in middle east, whereas founded in America the Arizona bark scorpion is considered as the venomous in the region.
