By definition, arthropod skeletons are external, a defining characteristic of the phylum; having both an internal and external skeleton would be redundant.

How are arthropods different from invertebrates?
Arthropods are invertebrates. An invertebrate is an animal without an internal skeleton and that's exactly what an arthropod is.
Do arthropods have a spine?
No, at least not in the backbone sense. Arthropods have their skeleton on the outside (exoskeleton); spines or vertebral columns are characteristic of vertebrates under a different phylum - Chordata, including fish, birds, mammals, etc.
Could an animal have both an internal and external skeleton?
Arthropods use external skeletons (exoskeletons).
Are all arthropods invertebret?
Correct, arthropods don't have vertebrae (spinal column) or an internal skeleton, instead they have an exoskeleton (external), made from a tough protein, chitin.
Is a backbone not common in all arthropods?
Correct, backbones are missing from arthropods because they are exoskeletal, having a tough outer skeleton rather than an internal skeleton (endoskeleton) like mammals, reptiles, amphibians, and so forth.
Does an ant have skeleton?
yes it has an exoskeleton Ants belong to a phylum called the arthropods. Arthropods have shells, which are classified as a type of external skeleton or exoskeleton. They do not have internal skeletons of the type that we vertebrates have.
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.
Is a rabbit a arthropod?
No, rabbits 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.
Are centipedes crustaceans?
The vast majority of centipedes are carnivores.
How Arthropods alike?
they all have exo skeleton
Do arthopods have backbone?
Arthropods is an exoskeletons, their components are external. This supports and protects the aminals inner body. No internal backbone
Are all Arthropods exoskeletal?
Yes, having an exoskeleton is a defining characteristic of arthropods. Animals with internal skeletons belong to three other phyla, for example Chordata - the chordates, including mammals, reptiles, amphibians, etc.
