Do lobsters have a notochord

Lobsters do not have a notochord. Instead, they belong to the phylum Arthropoda, which is characterized by a segmented body, an exoskeleton, and jointed appendages. The notochord is a feature of chordates, a separate group that includes vertebrates and some invertebrates. Lobsters possess a different type of support structure, primarily relying on their exoskeleton for protection and support.
