The Galapagos Tortoise is a colossal terrestrial reptile, the largest in the world and can weigh up to 919 lbs and can live well over 100 years. This species is believed to have come from the mainland, as they are buoyant and can live for months at a time without food or water. The Galapagos tortoise is a herbivore, feeding on cacti, grasses, leaves, lichens, berries, melons, oranges, and milkweed. Within the archipelago, up to 15 species of Galápagos tortoises have been identified. Unfortunately, only 11 survive today. This species has captivated the minds of scientists and explorers, including the famous evolutionary scientists Charles Darwin and Galapagos founder Fray Tomás de Berlanga, Bishop of Panama
