Aldabra Giant Tortoise

Overview

One of the largest tortoises in the world, with a high domed shell and thick, columnar legs. Its long neck allows it to reach vegetation above its head. Males are significantly larger than females and individuals can live well over a century, contributing to long-term seed dispersal on Aldabra.

Classification

The Aldabra Giant Tortoise belongs to the suborder Cryptodira (hidden-neck turtles) and the family Testudinidae. It is the family of true tortoises — exclusively terrestrial turtles with domed shells and stumpy, elephantine limbs. Its scientific name is Aldabrachelys gigantea.

Appearance & Distinguishing Features

Members have high-domed, heavily ossified carapaces and column-like hind limbs adapted for walking on land rather than swimming. Size ranges from a few centimetres to the giant tortoises exceeding 1 m.

Habitat & Distribution

They occupy a wide range of terrestrial habitats across Africa, Madagascar, Eurasia, the Mediterranean, and the Americas, from deserts to tropical forests and grasslands.

Diet & Feeding

They are predominantly herbivorous, grazing on grasses, leaves, flowers, and succulent plants, with some species favouring fruit.

Behavior & Conservation

Tortoises are celebrated for exceptional longevity, with many species living several decades and the largest surpassing a century. Several popular species are kept as pets, while others are threatened by habitat loss and collection.

Popularity & Recognition

Among the most familiar pet reptiles worldwide (such as the sulcata and Russian tortoise), they are also cultural symbols of slowness and endurance.
