About the scorpion

Scorpions are arachnids, relatives of spiders, with eight legs, a pair of pincers and a tail ending in a venomous sting, and the roughly 2,500 species live on every continent except Antarctica, from deserts to rainforests. They glow blue-green under ultraviolet light, can slow their metabolism to survive a year without food, and give birth to live young that ride on the mother's back. Only around 25 species have venom dangerous to people; the emperor scorpion of West Africa, up to 20 centimetres long, is one of the largest and a common pet.

Five things to know

  1. All scorpions are venomous, but less than 30 species are dangerous to humans.
  2. Scorpions glow blue-green under ultraviolet light due to substances in their exoskeleton.
  3. Some scorpions can live more than 20 years, especially in captivity.
  4. Their pincers are used to grasp prey, while the tail delivers venom.
  5. Scorpions have been on Earth for over 430 million years, making them ancient arachnids.
