No, crabs are not chordates. They belong to the phylum Arthropoda, which includes insects, arachnids, and other crustaceans. Chordates, on the other hand, are part of the phylum Chordata and possess a notochord, a dorsal nerve cord, and other defining features at some stage of their development. Crabs lack these characteristics, placing them in a different biological classification.
Arthropods belong to a major classification in taxonomy, characterized by joint appendages, external skeletons, and segmented bodies. They include arachnids, sea Spiders, horseshoe crabs, myriapods (like millipedes), and crustaceans like true crabs, shrimp, and lobsters. They also include all the insects.
