The name crustacean, which derives from the Latin word crusta, which meaning shell, refers to all members of the phylum Arthropoda Crustacea. The group of invertebrate organisms known as crustaceans is incredibly varied and includes both sessile and active species like barnacles as well as active species like crabs, lobsters, shrimp, krill, copepods, and amphipods. The biggest phylum in the animal kingdom is called Arthropoda. In total environments, it has roughly 11,340,000 species. Approximately 83% of all animal species on Earth are represented by this. Arthropoda encompasses a wide variety of insects, such as spiders, scorpions, prawns, crabs, millipedes, and centipedes. Arthropoda are known for their linked appendages, chitinous exoskeleton, and heteronomous metamerism. Arthropodization is the process through which these features evolve. The overall body surface of extremely tiny crustaceans serves as the conduit for the exchange of breathing gases. While terrestrial animals breathe via the trachea and book lungs, large aquatic arthropods breathe through gills and book gills.
