The new frontier of Biodiversity ! The marine area with the highest recorded diversity of fish and invertebrate species in the world. This area boasts extraordinary straits enclosed by calcareous islands all covered by tropical rainforest. The huge area of Raja Ampat represents a big marine reserve, that stretches out to the north (Waigeo and neightbouring island) and to the south west (Misool). The whole region is a labyrinth of straits between small sandstone islands eroded by the waves.
