Item 68 (Sushi)

68. Crab, crayfish, and lobster all have teeth in their stomach. This is called a gastric mill. With this digestive system, food passes through the esophagus to the stomach where the teeth made of chitin and calcium carbonate grind the food into a paste. Here is a picture of sushi with crab inside of it. Or, according to the label, "imitation crab".
