The stomach of a sea star is located in the center of its body, just beneath the arms. Sea stars have a unique feeding mechanism where they can evert their stomachs out of their bodies to envelop and digest prey externally. This allows them to effectively break down food before pulling the digested material back into their bodies.

Does a Sea Star have a one way stomach or two?
A sea star has a unique feeding mechanism that involves a one-way stomach. When it captures its prey, usually bivalves, it can evert its stomach through its mouth and into the shell of the prey to digest it externally. This allows the sea star to absorb nutrients directly from the digested material before retracting its stomach back into its body. Thus, it effectively has a single, functional digestive cavity.
Where does food move in the sea star?
In sea stars, food moves through a unique digestive system that includes a stomach and a complex network of digestive glands. After capturing prey, the sea star extrudes its stomach out of its body and into the prey to digest it externally. The digested nutrients are then absorbed into the sea star's body through the stomach and transported to other parts via the coelomic fluid. This efficient system allows sea stars to feed on a variety of marine organisms, primarily bivalves.

How does a sea star feed on a clam?
It forces its stomach out, and sticks it inside of the clams shell. Then with the clam inside of the stomach, the starfish puts its stomach back on its inside. A sea star opens up a clam by attaching its hundreds of tube feet to the external surface of the shell with suction. Then, it pulls. It might have to pull for hours, or days, until the adductor muscle holding the shell firmly closed is finally weakened enough that the shell opens. Then the star fish can force its stomach in and digest the soft insides of the clam.
