Why in News?
The Aldabra Giant Tortoise is in the news because Indian Prime Minister Narendra Modi visited the National Botanical Garden in Seychelles, where he met and fed these iconic creatures.
Geographic Distribution & Habitat
- Endemic Origin: The species is native exclusively to the remote Aldabra Atoll in Seychelles, located in the western Indian Ocean.
- Habitat Diversity: They occupy a wide range of land environments, including scrub forests, coastal dunes, mangrove swamps, and beaches.
- Tortoise Turf: Their heavy grazing on flat grasslands ("platins") shapes a unique, dense plant ecosystem known as "tortoise turf".
Physical Features & Behaviour
- Massive Size: It ranks as the second-largest land tortoise species globally, surpassed only by the Galapagos giant tortoise.
- Weight and Shell: Adult males can weigh over 250 kilograms (550 lbs) and feature a thick, highly domed, dark Gray to black shell.
- Unique Neck Plate: Unlike other giant tortoises, their upper shell has a small visible neck plate.
- Feeding Adaptations: They possess very long necks to reach high tree branches and specialized nasal structures to drink from shallow water pools.
- Diet: While primarily herbivores feeding on grasses and fruits, they are opportunistic and occasionally consume insects or carrion.
Conservation & Threats
- IUCN Status: It is classified as Vulnerable on the IUCN Red List and protected under CITES Appendix II.
- Population Recovery: Once driven near extinction by human poaching in the 20th century, strict protection has allowed their population to bounce back to over 100,000.
- Climate Vulnerability: Rising sea levels due to climate change pose an existential threat, as the highest point of their home atoll sits only 50 feet above sea level.
