A scorpion is an arachnid, closely related to spiders and ticks. They have eight legs and a segmented body, which includes a distinctive curved tail that often ends in a venomous stinger. Scorpions are primarily nocturnal predators, feeding on insects and small animals. They are found in various habitats, including deserts, forests, and grasslands. Scorpions are known for their ability to survive in harsh environments, with some species able to withstand extreme temperatures and limited water. There are over 1,500 species of scorpions worldwide, and their venom varies in potency, with some being dangerous to humans while others are harmless.
