Scorpions are arachnids that are found in almost every part of the world, except for Antarctica. They are known for their distinctive appearance, with two pincers and a curved, segmented tail that ends in a venomous stinger. Scorpions are nocturnal and feed on insects, spiders, and other small prey. They are known for their ability to adapt to harsh environments, and some species can survive in extreme conditions like deserts and caves. While scorpion stings can be painful and even deadly to humans, they play an important role in controlling insect populations and are also a vital part of the ecosystem.
