This product is made by cutting a whole horsehair crab and serving it on the shell, including the tomalley. Hairy crabs are smaller than other crabs, making them difficult to pick up, and the fine hair and thorns on the shell can easily hurt your hands. It is said that it was developed so that it can be easily eaten there.
