Aldabra Tortoise
Geochelone gigantean

Losing Giants: Seafarers visiting the remote island homes of giant tortoises inadvertently left trouble behind. Goats they released to feed future voyagers overgrazed the vegetation, leaving tortoises little to eat. Introducing pigs, and rats that jumped ship, destroyed tortoise nests and ate hatchlings. By 1850, few giant tortoises species survived.

Natural Diet: Primarily grasses and other vegetation occasional carrion (dead animals).

Reproduction: Female digs shallow nest to lay four to 15 eggs. Male makes a deep groaning mating call: listen for it!

Status: Wild population is around 150,000.

Weight: Up to 180 kg (400 lb)

Range: Aldabra atoll, and the Seychelle Islands (introduced) of the Indian Oceans

Habitat Grassland, scrub, and mangrove swamps
