6 Worst Scorpions in the World

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 sting. Scorpions range in size from 9–12 mm (0.35–0.47 in) in Microtityus minimus to 23 cm (9.1 in) in Heterometrus swammerdami.

The evolutionary history of scorpions goes back to the Silurian period 435 million years ago. They have adapted to a wide range of environmental conditions, and they can now be found on all continents except Antarctica. There are about 1,750 described species, with 13 extant (living) families recognised to date. Their taxonomy is being revised in the light of genomic studies.

The vast majority do not represent a serious threat to humans, and healthy adults usually do not need medical treatment after being stung. Only about 25 species have venom capable of killing a human. In some parts of the world with highly venomous species, human fatalities regularly occur, primarily in areas with limited access to medical treatment.

Scorpions with their powerful sting appear in art, folklore, mythology and numerous brands. Scorpion motifs are woven into kilim carpets for protection. Scorpio is the name of a constellation and the corresponding astrological sign; a classical myth tells how the giant scorpion and its enemy, Orion, became constellations on opposite sides of the sky. The name has been used for a Roman siege engine, several warships, a type of tank, and a yoga pose with the legs pointing forwards over the head, like the animal's tail.
