A starfish doesn’t eat through its mouth. It actually shoots its stomach out of its body to capture food. The stomach begins to digest the food immediately, and then the starfish draws it back into its body with the food inside it. Starfish can even use their water vascular system to force open the shells of clams and mussels, wedge their stomachs into the shells, and begin eating the unlucky prey inside its own shell. The food enters another stomach, where the rest of the digestion process. Starfish mouths aren’t very big, so the two-stomach system allows a starfish to eat prey that wouldn’t fit inside its mouth.
