What is the largest grop of artherpods?

The largest group of arthropods is the class Insecta, commonly known as insects. This diverse group includes millions of species, making up about three-quarters of all known living organisms. Insects are characterized by their three-part bodies, compound eyes, and exoskeletons, and they inhabit a wide range of environments across the globe. Other significant groups of arthropods include arachnids (like Spiders and scorpions) and crustaceans (like crabs and lobsters), but insects far outnumber them in species diversity.
