Yes, researchers now say. Not only do crabs suffer pain, a new study found, but they retain a memory of it (assuming they aren't already dead on your dinner plate). The scientists say its time for new laws to consider the suffering of all crustaceans.
The study involved using wires to deliver shocks to the bellies of hermit crabs, which, being hermits, often take up residence in left-behind mollusc shells. The crabs that were shocked scampered out of their shells, "indicating that the experience is unpleasant for them," the scientists concluded; unshocked crabs stayed put.
Another test was run to see what would happen if a mild shock was delivered, one just below the threshold that would cause the crabs to leave home. These mildly shocked crabs, along with crabs that had not been shocked, were then offered a new home. The typical reaction: They'd go inspect the new shell. Significantly, those that had been shocked were more likely to pack up and move to the new residence compared to those that hadn't been shocked.
But a study by Elwood and colleagues in 2007 found prawns were irritated when their antennae were treated with acetic acid, and after a local anesthetic, they'd stop rubbing the antennae. He said this was evidence that they suffer pain, and that lobsters likely feel pain, too.

Is it that surprising that crabs feel pain? I didn't realize people were under the impression they didn't. I can't believe anyone found a need to do a study on that, haha. If you know anything about cooking crustaceans (I'm from New Orleans, so I'm quite familiar with the process) you can't just throw them straight into a pot of boiling water. The shock from the pain will usually cause many of their limbs to just pop out. How horrid. Instead, you throw them in the fridge for a while. It knocks them unconscience pretty quickly. It's still sucks they have to eaten, but that's the way of things. Big animals eat little animals. Humans are bigger than crabs. An easy enough formula to follow.

Lizards do it too. To distract predators (and kids) while they escape.
