Indian Ocean islands
The 115 islands which make up the Seychelles can be divided into two types, granitic islands or coralline islands, with the biodiversity differing between the two types.
The older granitic islands, once part of the supercontinent Gondwanaland, are home to a much higher number of endemic species. The younger coralline islands are also important, supporting seabird colonies, turtle rookeries and most of the archipelago’s coral reef systems.
