In 2007, our guest, Fabrice Schnöller, was sailing off the coast of Mauritius, in East Africa, when he had an encounter that would change his life and open a new frontier in marine biology. As his boat neared land, huge pillars of steam burst out of the water and began surrounding the boat. Schnöller, an experienced diver, grabbed his snorkeling gear and jumped in to investigate. No sooner had he slipped under the water than he was overwhelmed by a crashing, creaking sound. Glancing downwards, he discovered a set of what appeared to be huge, dark monoliths accelerating towards him.
