Does an arthropod have a backbone?

Answer 1

Arthropods don't have backbones. The vertebral column or spine comprises individual bones (vertebrae) as part of an internal skeleton or endoskeleton. Arthropods by contrast have no bony internal skeleton, instead they rely on a chitinous external or exoskeleton, consequently they also evidence the joint appendages and segmented body which characterize the phylum.
