Several Skunk Anemonefish Clown fish (Amphiprion ephippium) populate a Magnificent Sea Anemone (Heteractis magnifica). Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. The Anemone has stinging venom coated polyps, which the Anemone fish has the ability to cover its body with and use as protection from predators. In return, the Anemone fish constantly eats parasites from the Anemone, keeping it clean. A perfect demonstration of a symbiotic relationship in nature. The location is Phi Phi, Andaman Sea, Krabi, Thailand.
