It is called toilet water.
Most starfish eat mollusks, principally bivalves which they force open by seizing both halves of the shell with their tube feet and pulling the halves apart very slowly until the bivalve is exhausted.
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.
