Full Answer

Various species of crab have slightly different diets. They have a very strong digestive system that permits them to eat fungi, mollusks, bacteria, worms and even other crustaceans, such as shrimp or barnacles. In times of desperation, they have been known to eat the offal from the sea floor, which can include dead and decaying animals.
