Yes they do, but you wouldn't really notice because their blood is blue (or can appear clear) in colour due to a lack of hemoglobin. Also, they don't have blood vessels, their blood just moves around in gaps between the organs and muscle tissue, so if their skin is broken they can bleed to death.

∙ 10y agoThe reason for the crab's 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.
