The correct answer is: Arthropod.<\/p>\n
Arthropods are the largest phylum of animals, comprising over 80% of all animal species on Earth. They are characterized by their jointed exoskeleton, segmented body, and paired appendages. Arthropods include insects, spiders, crustaceans, and millipedes.<\/p>\n
Mollusca are the second largest phylum of animals, comprising about 8% of all animal species. They are characterized by their soft bodies, often protected by a hard shell. Mollusca include snails, slugs, clams, oysters, and octopuses.<\/p>\n
Chordata are the third largest phylum of animals, comprising about 4% of all animal species. They are characterized by a notochord, a dorsal nerve cord, and pharyngeal slits. Chordata include vertebrates (animals with a backbone) and invertebrates (animals without a backbone).<\/p>\n
Coelomates are animals that have a coelom, a body cavity that is lined with mesoderm. Coelomates include all animals except sponges, cnidarians, and flatworms.<\/p>\n
In conclusion, the largest animal phylum is Arthropoda.<\/p>\n","protected":false},"excerpt":{"rendered":"
