Habitat
Native to Aldabra Atoll in the Seychelles, where over 100,000 individuals graze grasslands, mangroves, and coastal scrub. Introduced populations live on several other Seychelles and Mascarene islands.
Climate & seasons
Tropical maritime: 25–32 °C year-round, high humidity, monsoonal rains. Shelters under bushes and in rocky crevices during midday heat.
Diet
Mostly grasses and herbs, supplemented with leaves, fruit, and seedlings. Plays a major role in seed dispersal across Aldabra — what they eat shapes the island's vegetation.
Temperament
Gentle, slow, and habituated to people in their native range. Adults are calm enough to be hand-fed by researchers.
Shell & anatomy
High-domed carapace, dark brown to almost black. Massive columnar legs. Long neck for browsing low branches. Bulls reach 250 kg (550 lb).
Conservation status
IUCN Vulnerable, but the native Aldabra population is stable and well protected. The species was almost wiped out by sailors in the 1800s — saved by an early conservation campaign led by Charles Darwin and others. CITES Appendix II.
As a pet
Legal in some places but a multi-decade, several-acre commitment. Most are kept in zoos and large private collections; not realistic for a typical home.
Field notes
- Aldabra Atoll alone holds more giant tortoises than there are people on most small countries.
- Darwin's letters helped persuade the British government to protect Aldabra in the 1870s — one of the world's earliest conservation campaigns.
- Free-roaming Aldabras on Curieuse Island have rebuilt entire ecosystems by dispersing native seeds.
