What is a sea stars favorite food?

Do starfish eat themselves?
However, sea stars have a unique way of eating these creatures. A sea star’s mouth is on its underside. When it catches its food, the sea star will wrap its arms around the animal’s shell and pull it open just slightly. It then digests the animal and slides its stomach back into its own body.

How does a starfish eat an oyster?
