Aldabra Giant Tortoise
It is amazing how many different species you can see just in one morning or afternoon walking around the island. I only had a day to soak up Mauritius before boarding my flight back to the UK so I chose to spend as much of it as possible on Ile aux Aigrettes. Aldabra Giant Tortoises have been introduced to replace the extinct giant tortoise species once found there on the island.
They were introduced from the Aldabra Atoll in the Seychelles to fill the niche the extinct giant tortoise once had. The giant tortoises, and now the Aldabra Tortoises, ate the fruit of the trees on the island, spreading the seeds. Without these fruit-eaters around, the trees could no longer disperse. Young trees would only grow directly below the adults.
Although unverified, Aldabra Giant Tortoises are thought to live over 200 years of age.
