There are green sea turtles in San Diego Bay? Where did they come from? Do they really live over 100 years? Why is it important for scientists to keep track of these giant creatures, and how on earth do they do it? In this interview with ecologist Tomoharu Eguchi (NOAA Marine Fisheries Service) and ecology graduate student Sheila Madrak, we meet the sea turtles and explore these 'big' questions.
