| | Expedition Pursues Secrets of Clipperton Island |
 | | Clipperton is included on the list of protected areas of the United Nations Environment Program (UNEP), which classifies it as ''one of the least altered island systems in the Pacific Ocean,'' and ''the fauna and flora consist of an unusual assemblage including both Panamic (American) and Indo-Pacific forms.'' |
 | | In the case of Clipperton Island, after the volcano ended its active phase it began to sink, and its crater became a lagoon, protected from the sea and from external biological influences. |
 | | Clipperton ''is a geo-chemical laboratory unique in the world,'' because the water in its lagoon lacks oxygen deeper than eight meters, and contains high proportions of sulfuric acid, making it a ''natural melting pot where phosphates are formed, and an ideal environment for the emergence of new organisms,'' Etienne explained. |
