"Giant Galápagos tortoises have roamed the Galápagos Islands for thousands of years, but these creatures almost disappeared from their tropical habitat. Giant Galápagos Tortoise describes the world's largest tortoise, how sailors and invasive species caused its population to dwindle, and how habitat preservation and captive breeding have helped save the species."--Publisher's website.
