Mauritius

Of particular interest is the Rodrigues coral reef.

An excerpt from the article 25 facts about Mauritius

It is self-sown and does not receive coral zooplankton from other sources. It is thus poor in species, but the existing ones show very good adaptation. Coral species, two species of Pomacentrus (a genus of marine damselfish in the Pomacentridae family), and many species of crustaceans are found only on Rodrigues reefs.
