Spiders belong to the class Arachnida, which is characterized by having eight legs. This is a distinguishing feature of arachnids, setting them apart from insects, which typically have six legs. The eight legs of spiders are an adaptation that allows them to be highly efficient predators, using their limbs not only for locomotion but also for capturing prey and building webs. The structural composition of a spider's legs also plays a critical role in their ability to sense the environment and aid in their agility. Understanding this foundational aspect of spider anatomy is essential in differentiating them from other arthropods, such as insects or crustaceans, which have different leg counts and body structures.
