It is well-known that the Seychelles in the Indian Ocean is home to a spectacular assortment of marine species. From large sea fans and whip corals to Eagle Rays and Moray Eels to fierce species like the Giant Trevally and Dogtooth Tuna. All of these species bound together in the tropical waters of the Seychelles and form an intricate underwater ecosystem.
But the Seychelles is also home to a number of incredible land-dwelling species, like the curious Aldabra Giant Tortoises.
Giant Tortoises can only be found in two places in the world today - the Aldabra Atoll in the Seychelles and the Galapagos Islands in Ecuador.
These ancient creatures can weigh well over 400kg and grow to be roughly 1.3m in length. Some individuals have grown over 250 years old, but most live between 80 and 120 years.
Due to their long lifespan, they only reach sexual maturity at around 30 years. Once mated, the female will lay roughly 25 eggs in a dry, shallow nest and incubation takes up to 8 months. All of this makes predation and hunting of the species a very real problem.
During the 1700s and 1800s, most of the Giant Tortoise species were driven to extinction due to the over-population of European settlers and introduction of predators like cats and dogs as well as goats which would devour large quantities of vegetation before the slow-grazing giants could get to it.
Believed to have once occurred on all continents, except for Australia and Antarctica, the Giant Tortoise has now been reduced to a handful of populations.
Luckily (and most likely due to its remoteness), the species on Aldabra Atoll remains and is now being protected as the whole of Aldabra has been declared a World Heritage Site.
The Aldabra Giant Tortoise and the Seychelles Giant Tortoise are so similar genetically that it was once believed to be the same species.
This might have also added to the species having had 4 different scientific names through the years.
Today, all tortoises found in the Seychelles are Aldabra Giant Tortoises which is one of the largest species in the world.
When Alphonse Island was first discovered, there were no tortoises on the island, but in 1999 the first 10 were introduced.
Along with the help of the Island Conservation Society (ICS) and their dedicated conservation centre on the island, Alphonse Island has been able to monitor and keep track of the population's growth and well-being.
There are currently 51 Aldabran Giant Tortoises ranging from hatchlings to full-grown adults living freely on the Island.
These large, slow-moving creatures are herbivorous and can be spotted grazing on the Island and using their long necks to break off leaves from foliage growing higher up. They have also been known to eat fruits and berries.
Be sure to keep an eye out for these gentle giants when exploring the Island!
