Describe how a star fish feeds on a clam?

A starfish feeds on a clam by first using its tube feet to pry open the clam's shell slightly. Once the shell is opened, the starfish extends its stomach through its mouth and into the clam's body, secreting digestive enzymes to break down the soft tissue. After digestion, the starfish retracts its stomach, absorbing the nutrients. This process allows the starfish to consume prey that is otherwise protected by a hard shell.
