Do you mean the Crown of Thorns Starfish?

The Great Barrier Reef .
Major Natural Predator:

The Crown-of-Thorns Seastar was once an animal of great controversy causing terrible damage to the coral reefs of the Great Barrier Reef. Many believed that this seastar was a pest species invading the coral reef habitat predating on and killing corals in great numbers. Research has indicated that the Crown-of-Thorns Seastar is only found in this habitat and a native species to Australian waters. The role that the sea star plays by eating coral polyps forms a population control, making more room for new coral reefs to form. Plague proportions are thought to coincide with rainfall and increases in nutrients from rivers during floods, and often occur cyclically every 17 years. Further scientific studies are still in progress to determine whether these plaques can be controlled. Source(s): http://www.barrierreefaustralia.com/the-...
