Invertebrates do not have a spine (backbone) like vertebrates do. Fish, Birds, Reptiles, Amphibians, Mammals are vertebrates with internal skeletons, spines, heads, and brains with central nervous systems. All insects are invertebrates and they mostly have exoskeletons (external skeletons), and no backbones. Their internal organs make up the entire contents of their interior structures.

Are crabs Invertebrates.?
Yes, as a vertebra is a piece of a backbone. As such invertebrate means an organism that does not have a spinal column or back bone. Crabs have an exoskeleton (their external shell serves as a skeleton) instead of a back bone, they are therefore considered invertebrates. Crabs have no bones, including no vertebrae (backbones). They are invertebrates.
