Where coral grows in abundance, so too grow tens of thousands of seaweeds, sponges, shells, shrimps, crabs, fish, sea urchins, and starfish. Species of fish and smaller creatures live together in a coral reef, forming an ecological food chain.
在珊瑚聚集的世界裡，數以萬計的海藻、海棉、貝、蝦、蟹、魚、海膽、海星及魚類和微小生物在珊瑚礁區共生棲息，生物間形成複雜的生態關係。
