In general appearance very similar to the common shore-crab.
Crabs are distinguished from the lobsters by their compact form, and by having the short tail turned in under the body. There are a great number of species, differing much in size, shape, and appearance. One of the best known in England is the large Edible Crab, which may often be seen in fishmongers' shops, and, unlike the lobster, does not change much in colour when boiled. Every visitor to the seaside must have seen numbers of the little greenish Shore-crabs, running about on the sand, or over seaweed-covered rocks, at low tide. These small crabs are harmless, but large kinds are able to give a very severe pinch. It is related that when the great chemist Sir Humphry Davy was a boy he used to maintain that pain was no evil, until a large crab gripped his toe one day when he was bathing, after which he changed his opinion.
