Crabs use their claws to acquire and manipulate food. They also use the claws for some food processing, and to help move food toward the mouth. Crabs have specialized mouth parts for finer food processing. Once the food particles are small enough, they are moved into the digestive tract into a chamber in the stomach called the gastric mill, where the food is further processed into smaller particles and nutrients. These are then passed on and either absorbed or excreted.
