They don't have mouthparts. They exude their first stomach from their bodies and into the bivalves they commonly eat. This stomach digests the meat inside the shell and then is drawn back into the starfish to be further digested by the secondary stomach. The starfish is a predator of bivalves such as clams and mussels, but is known to scavenge as well.
