Arachnida is a class of arthropods, characterized by having eight legs, two body segments (cephalothorax and abdomen), and typically lacking wings or antennae. This diverse group includes spiders, scorpions, mites, ticks, harvestmen (daddy longlegs), and pseudoscorpions. Arachnids are primarily terrestrial, although some species inhabit aquatic environments. They play crucial roles in ecosystems as both predators and prey, contributing to the balance of insect and invertebrate populations, with a wide range of habitats. Reproduction involves egg-laying and subsequent development through various life stages. They also often possess venom glands or other defensive mechanisms.
