On and on. the indefatigable island tortoise can live for more than 150 years, and is able to survive for months without food and water. Over the years, this gentle giant of the Galapagos has developed a symbiotic relationship with other animals that share its home, including birds that feed on ticks attracted to the tortoise. But it has not been as fortunate with its relationship with humans, who harvest the tortoise for meat and oil and also introduced species like rats and goats that destroy its young and compete with it for food. The question is how long can the tortoise go on?
