The Charles Darwin Research Station is home to tortoises ranging from 3-inches (new hatchlings) to 4-feet long. Sub-species of tortoises interact with one another and many of the older tortoises are accustomed to humans, stretching out their heads for a photo opportunity. The babies are kept until they are about four years old and strong enough to survive on their own.
"Turtles" live in water and "tortoises" live on land. You cannot touch the tortoises (or any other animals) in the Galápagos.
