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.

Is a bunny an arthropod?
No, bunnies have a backbone (spine) and are chordates (phylum Chordata) along with other mammals, lizards, birds, amphibians, etc. To be an arthropod (phylum Arthropoda) you'd need to have an external skeleton (exoskeleon) made from chitin.
Which of these has an exoskeleton arthropod worm vertebrate cnidarian?
An arthropod
Is the portuguese man of war an arthropod?

Is a tiger an arthropod?
No, tigers are chordates - phylum Chordata, a different phylum than Arthropoda (the arthropods). Pretty much anything with an internal skeleton and backbone like mammals, birds, reptiles, amphibians, will be chordates. Arthropods have their skeleton on the outside (exoskeleton), like the insects or crustaceans.
