A Glimpse into the Aldabra Atoll
Aldabra Atoll, a UNESCO World Heritage site, is the world’s second-largest coral atoll and forms part of the Seychelles archipelago. This isolated haven, untouched by human habitation, has allowed a diverse range of flora and fauna to thrive, with the Aldabra Atoll tortoise being its most famous inhabitant.
The Aldabra Atoll Tortoise: A Living Wonder
The Aldabra giant tortoise is one of the largest tortoises in the world. These reptiles are known for their impressive size, with some of them weighing over 550 pounds and measuring up to four feet in length. Their lifespan is equally remarkable, with many living well over a century, some reportedly reaching over 200 years.

A Journey of Survival
The survival story of the Aldabra Atoll tortoise is one of triumph over adversity. Once on the brink of extinction due to overexploitation by sailors in the 18th and 19th centuries, they were brought back from the edge through rigorous conservation efforts. Today, their population on the Aldabra Atoll is estimated to be around 100,000, making it the world’s largest population of giant tortoises.
