Tortoises are reptiles known for their distinctive hard shells, which protect them from predators. They belong to the order Testudines and are primarily land-dwelling creatures. Tortoises are herbivores, feeding mainly on grasses, leaves, and fruits. They are slow-moving animals, often living for several decades, with some species reaching over 100 years of age. These creatures are found in various habitats, including deserts, forests, and grasslands. Tortoises are ectothermic, meaning they rely on external sources to regulate their body temperature. Some well-known species include the Galápagos tortoise and the African spurred tortoise, each adapted to their specific environments.
