Arthropod classification is the process of organizing arthropods, a diverse group of invertebrates that includes insects, arachnids, crustaceans, and myriapods. These animals are characterized by their segmented bodies, exoskeletons made of chitin, and jointed appendages. The main subphyla of arthropods are Hexapoda (insects), Chelicerata (spiders and scorpions), Crustacea (crabs and lobsters), and Myriapoda (centipedes and millipedes). Within each subphylum, arthropods are further divided into classes and orders based on specific traits. For example, the class Insecta under Hexapoda includes orders like Coleoptera (beetles) and Lepidoptera (butterflies and moths). This hierarchical classification helps scientists understand the relationships and evolutionary history
