NMSAS - Crown Of Thorns Star fish

National Marine Sanctuaries

That's a big starfish -- and a big problem! In recent years, the crown-of-thorns starfish, or alamea, population has exploded in National Marine Sanctuary of American Samoa. These starfish eat stony corals that form the essential foundation of coral reefs, and as their population skyrockets, the reef suffers.
