Do crabs have toxins?

Some species are not always toxic, so it is likely that the toxins are obtained through the crab's diet or possibly by symbiotic bacteria. Crabs have no mechanism for delivering these toxins, such as through a bite or poisonous spines, so poisoning only occurs when people consume the crabs.
