Absolutely, and it can be quite dangerous for the crab, especially land-crabs. Their blood is blue in color, because they use a copper-based molecule (hemocyanin) to carry oxegen where we use an iron-based one (hemoglobin). Crabs, like spiders, have an open circulatory system, where the blood just bathes freely over the internal organs and tissues, so if their exoskeleton (shell and joints) is cracked, they blood just oozes right out. and because they use their blod like hydraulic fluid to move their legs as well, the leak can leave them unable to move eventually. If the leak is in a leg, they willl often just pull their own leg off to stop the bleeding, "cause at the joint there are muscles that can cinch up and close off the flow.
he he...this one is funny. I think I know my crab...I would say somewhat...bleed blood...no, not likely...but honestly I truly believe crabs don't possess blood. It may ooze a somewhat white, yellowish something a' somekinda substance ...but never seen blood in Stone,Snow,Blue,Dungeness,Alaskan King Or Jumbo...never
