can a Crustacean be considered an Invertebrate?

I understand that they share an exoskeleton but does this really count? Does a lobster or a shrimp have a spine?

    Crustaceans are a subphylum of Arthropods which are in turn invertebrates.

    So no, it isn't a vertebrate, the exoskeleton does not characterise vertebrates; backbones/spinal cords do.

    Crustaceans are invertebrates. all of them. since crustaceans fall under the order arthropoda, and all orders lower than chordata are considered invertebrates, therefore arthropods are invertebrates. having an exoskeleton doesn't really affect or relate to the classification whether they are invertebrates or not.

    A lobster's closest genetic relative is the cockroach.

    Yes they are invertebrates because they lack vertebral column.
