The radiated tortoise (Astrochelys radiata) is a species of tortoise native to the island of Madagascar, located off the southeastern coast of Africa. Here’s a description of its distribution:

1. Madagascar: Radiated tortoises are endemic to Madagascar and are found throughout the southern and southwestern regions of the island. They inhabit various habitats, including dry spiny forests, scrublands, and coastal dunes. Radiated tortoises are particularly common in the arid and semi-arid regions of Madagascar, such as the regions of Toliara, Ihorombe, and Atsimo-Andrefana.

Radiated tortoises are well-adapted to their arid environment, with a domed shell that helps regulate body temperature and conserve moisture. They are primarily herbivorous, feeding on a variety of vegetation, including grasses, leaves, flowers, and succulent plants.

Despite being native to Madagascar, radiated tortoises face significant threats from habitat loss, habitat degradation, and poaching for the illegal pet trade and traditional medicine markets. They are listed as critically endangered by the International Union for Conservation of Nature (IUCN), and conservation efforts are underway to protect remaining populations and their habitats. This includes the establishment of protected areas, breeding programs, and initiatives to raise awareness about the importance of conserving this iconic species.
