In Seychelles, there is a world-famous Tortoise Island, part of the Aldabra Atoll, southwest of Mahé.It is the largest island in the Seychelles and the second-largest coral atoll in the world.The island is over 30 km long and 15 km wide, only 1–2 meters above sea level, with strong currents and hidden reefs around, making it difficult for humans to access.About 150,000 land tortoises live here; due to their huge size, they are known as “Aldabra giant tortoises”.

The average carapace length of adult males is 120 cm, weighing up to 250 kg.They are slow-moving animals with short, strong limbs; their hind legs are cylindrical like those of elephants.Their bodies are covered with thick, usually bony scales.They have short, two-jointed toes.Their short, round, almost flat feet help them walk on sand.
