Question

Did you know? The crown-of-thorns starfish (Acanthaster planci) is a deadly threat to coral reefs. One adult eats 6 m² of coral per year. During an outbreak — sometimes millions at once — it can destroy entire reefs in months. The Australian Great Barrier Reef has lost three-quarters of its coral mass since 1980, partly due to this plague.
