In 1998, when the Réserve Naturelle was created, a total of 480 different species of flora and fauna were estimated to exist in the various zones on land and at sea.
But that was before april 2012, when a scientific mission listed more than 700 marine species!
This inventory of fauna was done with the support of seven university professors from United States, Brasil and France. The three classifications included in this study are crustaceans (shrimp, crabs...), mollusks (slugs, shellfish...), and echinoderms (sea urchins, starfish, ophiuroids...).
