Turtles are some of the oldest creatures on the planet. They have paddled through our oceans for at least 100 million years and during that time they have been slowly evolving along with the rest of the planet. In the last few centuries however, change has been happening a lot faster and these aquatic dinosaurs are struggling to keep up. Rainer von Brandis describes the seminal moment for his career as a turtle biologist.
