With a geological age of under four million years, and colonised barely four centuries ago, the island offers the world a unique spectacle.
- Underwater, the coral reef, although very young, is teeming with life. It takes only a few years for corals and fish to colonise the lava flows that reach the sea.
- On land, birds, butterflies and lizards show how imaginative life can be when forced to adapt to new conditions: the Reunion grey white-eye (Zosterops borbonicus) is said to be mutating into several subspecies.
Today, passionate volunteers and professional scientists are still discovering, or rediscovering, new species of plants and animals. The fauna of Reunion Island is definitely unique. The island has no dangerous or poisonous animals.
