(Published by Parragon, 2007) 6,793 different species of crabs are known.In addition there are about 850 species of freshwater or semi-terrestrial crabs.'True' crabs are decapod crustaceans of the infraorder Brachyura, whereas hermit crabs [decapod crustaceans of the superfamily Paguroidea] are classified quite differently due to physical characteristics. They are not even closely related to 'true' crabs. For more information, see Related Links below ads...
