The Order Scorpiones comprises scorpions, which are predatory arachnids known for their segmented tails ending in a venomous stinger. Scorpions have pincers (pedipalps) used to grasp prey and a tough exoskeleton that provides protection and reduces water loss, allowing them to thrive in arid environments. They are primarily nocturnal hunters, feeding on insects, spiders, and other small animals. Scorpions exhibit viviparous reproduction, with mothers carrying live young on their backs until their first molt. Widely distributed in warm and dry regions, they play an important role as both predators and prey in their ecosystems.
