Dr. Blake first met Samuel as the hatchling tortoise left its nest on the Galapagos Islands. A tiny tracking tag helped Stephen and his team track the little guy as he legged it away from his nest site, navigating the harsh volcanic landscape in search of safety and some edible foliage. Eight years later Samuel has grown to over 15 pounds and survived the most dangerous period of his life, which now could stretch on over the next century and beyond.
