A starfish is unable to bite because it lacks teeth. When a starfish eats, it lays on its pray and throughts up its stomach, similar to a fly, it then eats it stomach again with its prey.
When a starfish pries open the shell of a clam or oyster, it uses its tube feet to exert pressure on the shell. The mollusk instinctively tries to close its shell to protect itself, but the starfish can exploit even a slight opening. Once the shell is slightly ajar, the starfish extends its stomach out of its body and into the clam or oyster, secreting enzymes to digest the soft tissue before absorbing the nutrients. This method allows the starfish to feed effectively despite the mollusk's resistance.
