Overview: Michael Phelps joins Doc Gruber and Tristan Guttridge of the Bimini Shark Lab to get a crash course on everything ‘shark.’ They’ll dispel the myths and common misconceptions, teach him how to safely dive with sharks - including how to stay calm when a hammerhead swims two feet above his face - and will get Michael Phelps up close and personal with the incredible power of a Great White. Produced by Peacock Productions.
