Scorpions are arachnids, closely related to spiders and ticks. They have eight legs and a segmented body, which includes a distinctive tail that often ends in a venomous stinger. Scorpions are primarily nocturnal predators, feeding on insects and other small animals. They are found in various habitats, including deserts, forests, and grasslands, across many parts of the world. There are over 1,500 species of scorpions, with varying sizes and colors. While most scorpions have venom that is not harmful to humans, a few species, such as the Arizona bark scorpion, possess venom that can be dangerous. Scorpions are also known for their ability to survive in extreme conditions, making them resilient creatures.
