In order for a living organism to be classified as a vertebrate it must have a backbone, a central nervous system that is partly enclosed by this backbone, and also a muscular system.
Silverfish are insects and crabs are crustaceans, both invertebrates, they lack a backbone.

Do blue crabs have blood?
Yes. All crabs have blue blood, not just the species known as the blue crab. The reason for the blue blood is that crabs do not have haemoglobin, which is found in the blood of vertebrates, and which is red due to the iron molecule in the centre of the protein. Instead, crabs have a protein called hemocyanin, which contains a copper molecule. This is particularly pronounced in the horseshoe crab, the blood of which is a stronger blue than other species.
