The Mascarene Islands is a group of islands in the Indian Ocean east of Madagascar consisting of Mauritius, Réunion and Rodrigues (featured below). The island (capital Port Mathurin) used to be the tenth District of Mauritius and gained autonomy in 2002.
The 108 square-kilometre island is of volcanic origin and is surrounded by coral reef. Off its coast, you can spot some tiny uninhabited islands.
The coral reef of Rodrigues is of particular interest as it is self-seeding – it receives no coral zooplankton from elsewhere. This has led to an overall species-poor but highly adapted ecosystem. As a result, several species of coral, fish, and crustaceans can only be found on Rodrigues' reefs.
