The radiated tortoise (Astrochelys radiata) is a species in the family Testudinidae. Although this species is native to and most abundant in southern Madagascar, it can be also be found in the rest of this island, and has been introduced to the islands of Réunion and Mauritius. As the Radiated Tortoises are herbivores, grazing constitutes 80-90% of their diet, while they also eat fruits and succulent plants. A favorite food in the wild is the Opuntia cactus.
