Aldabrachelys gigantea
The second largest living giant tortoise, with a carapace to 138 cm and a uniformly black or blackish brown shell. It is notably social, moves in groups, and is known for good memory and colour recognition.
Aldabrachelys gigantea lives on the Aldabra Atoll of Seychelles and is the second largest living giant tortoise, with a carapace to 138 cm. The shell is uniformly black or blackish brown, the head is somewhat flattened, and head, neck, limbs and tail are dark grey. It copes poorly with heat: wild animals bask little, keep to the shade and, while feeding, turn the tail towards the sun so that the shell shades the head. On sunny days in the wet season it becomes crepuscular, resting in shade by day and bathing in water or mud. It is markedly social and gathers in groups to feed and to sleep. Intelligent, with good memory, learning ability and colour recognition, captive animals can be target-trained with food rewards to respond to particular colours. It is mainly herbivorous, eating grasses and the young shoots and leaves of shrubs, but will also take carrion and the dung of its own species.

Provide a basking spot at one end of the enclosure at about 32 C with an ambient temperature of about 27 C. A mercury vapour lamp is convenient because it supplies both UVB and heat. The species suffers in heat, so outdoor enclosures need shade, misting and a wallow.
It grows to 138 cm and needs a very large area, so it is unsuited to an ordinary home. It is a social animal, and keeping several together demands still more space and more than one basking area.
Mainly herbivorous, eating grasses and sedges and the young shoots and leaves of shrubs. A one-sided diet in early life leads to bone and shell problems as the tortoise grows fast, so offer a wide range of plants with plenty of fibre.
Placid and tames well, and intelligent enough to be target-trained. In the breeding season males mount one another to assert dominance.
The tortoise was covered by the Appendix II listings of Geochelone from 1975 and of Testudinidae from 1977, the current listing effective 2 January 2017. Appendix II species need no individual registration certificate in Japan, and it is neither a designated dangerous animal nor an invasive alien species. Seychelles has banned commercial trade in Aldabra-caught animals since 1980 and sets export quotas for animals from other islands.
