a sea otter eats a clam shell by using its strong teeth and paws to pry it open
No. Without their Tube Feet, they will be unable to move, nor to open a clam's tough shells.
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.
