Hermit crabs do not have backbones. They are invertebrates, with hard exoskeletons that protect their bodies. (However, the exoskeleton does not cover its soft abdomen.)
Butterflies have an exoskeleton. Ergo they're a hard invertebrate.
No they are not invertebrates because their skeleton is on the inside of their bodies unlike spiders or sow bugs which have skeletons on the outside of their bodies, and worms which have no skeleton at all.
Most invertebrates do not fossilize because of the lack of bones or exoskeleton. Soft tissue rarely fossilizes. B for PLATO users
