A tortoise is a slow-moving reptile known for its hard shell, which protects it from predators. Unlike turtles, tortoises primarily live on land and have sturdy, column-like legs. They are herbivores, feeding mainly on grasses, leaves, and fruits. Tortoises can be found in various habitats, including deserts, forests, and grasslands. Tortoises belong to the order Testudines, which includes all turtles and tortoises. They are long-lived creatures, with some species living over 100 years. Tortoises play an important role in their ecosystems by helping to disperse seeds and maintain plant diversity.
