Are the Giant Day Gecko's invertebrates or vertebrates?

All species of beetles are insects, and all insects are invertebrates. They have an exoskeleton, with no backbone or spinal cord. They belong to the Phylum Arthropoda, which includes organisms such as insects, Spiders, centipedes and millipedes, and crustaceans.

Vertebrates include only some members of the Phylum Chordata: specifically, mammals, birds, fish, reptiles and amphibians.
