Starfish have several natural predators. Among these are manta rays, larger fish and even larger starfish. Additionally, some species of sharks find starfish a delicious treat.
It depends what type of starfish you are talking about and whether it is in its own environment or introduced. If it is in its natural environment, it would eat and be eaten, but if it is an introduced species (e.g. Northern Pacific sea star) it may not have any predators and be competing for food with the native wildlife.
Sharks, Manta Rays, Sea Otters, and other large fish are the main predators of starfish.
