Tortoise, Aldabra

Aldabra atoll, northeast of Madagascar in Indian Ocean as well as the Seychelles archipelago. Some were brought to the remote island of Saint Helena in the South Atlantic, where Napoleon was exiled. For conservation purposes, the species was introduced to the island of Mauritius where they are now thriving.

There are many different habitats on the islands where tortoises can be found, including scrub, mangrove swamp, and coastal dune. The largest concentrations of tortoises are found on the grasslands.
