Phelps' Great White race isn't the only Shark Week special he'll be appearing in. The father of one will also join Doc Gruber and Tristan Guttridge of the Bimini Shark Lab to get a crash course on everything shark. Together, the trio will dispel myths and misconceptions and teach Phelps the proper way to get up close and personal with hammerheads and great whites.
Phelps vs. Shark: Great Gold vs. Great White airs Sunday, July 23 at 8 p.m. ET/PT and Shark School With Michael Phelps airs Sunday, July 30 at 8 p.m. ET/PT on Discovery.
While Phelps has an appreciation for sharks, his 1-year-old son, Boomer, is much more comfortable with the family's four-legged friends.
