No, sea stars use their tube feet to pry open the clam's shell and then evert their stomach into the clam to digest its soft tissues. Without the use of tube feet, the sea star would not be able to access the clam's flesh to consume it.

a sea otter eats a clam shell by using its strong teeth and paws to pry it open
Sea stars feed on different types of prey, such as bivalve mollusks, snails, and barnacles. One of their favorite foods is clam species. They use their tube feet to pry open the clam's shell and then push their stomach out to digest the soft tissues inside.
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.
The liquefied clam is then absorbed into the stomach. They feed often, and their size depends on the amount of food they eat, not on their age
