SHARK Sunday, July 22 at 8 p.m. ET / 5 p.m. PT Adventurer Bear Grylls returns to Discovery for the 30th anniversary of SHARK WEEK in a showdown of BEAR VS. SHARK. Grylls has survived the most extreme conditions – from the frozen peaks of Mount Everest to the blazing sands of the Sahara Desert. What will happen when he goes head to head with sharks on their home turf? It’s Grylls’ greatest test of wits and skill as he faces off with the ocean’s most fearsome predator. SHAQ DOES SHARK WEEK Sunday, July 22 at 9 p.m. ET / 6 p.m. PT Shaquille O'Neal accidentally signed himself for a face-to-face meeting with a shark underwater, but he is petrified of the iconic predator. To overcome his fear, O’Neal trains with former U.S. Marine and comedian Rob Riggle for the big dive. UNCAGED: SHARK VS. RONDA ROUSEY Sunday, July 22 at 10 p.m. ET / 7 p.m. PT With her trademark fighting spirit and determination, sporting superstar Ronda Rousey confronts one of her greatest fears in UNCAGED: SHARK VS. RONDA ROUSEY. Rousey is trained by shark conservationist and attack survivor Paul de Gelder to prepare to square off against her fiercest opponent yet. The former UFC champ kicks off her training by cage diving with several lightweight shark species in the waters off Fiji, then moves onto the main event in New Zealand for an uncaged free dive with the ultimate fighter of the sea, the mako shark. MONSTER TAG Monday, July 23 at 8 p.m. ET / 5 p.m. PT All-star athletes Aaron Rodgers, Lindsey Vonn, and Rob Gronkowski team up with expert shark scientists to learn about the ocean’s top predators in MONSTER TAG. Shark populations are in trouble around the world, but a daring collection of dedicated shark researchers are using the latest satellite technology to track and potentially save them. The researchers use satellite wildlife tags to determine where sharks feed, mate, and birth their pups – critical information in the quest to conserve the species. GREAT WHITE ABYSS Monday, July 23 at 9 p.m. ET / 6 p.m. PT Diving deeper than ever, a team of experts venture off to the great white shark hotspot Guadalupe Island to seek out the biggest sharks they can find in GREAT WHITE ABYSS. Previously in the waters surrounding the island, a six-metre female shark named Deep Blue surfaced, then disappeared into the deep. Dr. Mauricio Hoyos believes Guadalupe Island might be the area where all the giant sharks live. With deep-water cages and submarine dives, Dr. Hoyos teams up with Emmy® Award-winning cinematographer Andy Casagrande and expert shark diver Jimi Partington. CUBA’S SECRET SHARK LAIR Monday, July 23 at 10 p.m. ET / 7 p.m. PT In 1945, one of the largest sharks on record was captured in Cuban waters, a great white named “El Monstruo.” Since then, sightings of massive sharks have been frequent in Cuban waters, but the island nation has always been restricted from outsider interference. Discovery takes a dive into unexplored waters in CUBA’S SECRET SHARK LAIR, as two teams of researchers are granted permission to study Cuba’s massive sharks. Off the north shore, a team searches for another El Monstruo-sized great white shark. To the south, a team looks for a massive great hammerhead known as “The Queen.” GUY FIERI’S FEEDING FRENZY Tuesday, July 24 at 8 p.m. ET / 5 p.m. PT SHARK WEEK teams up with restaurateur Guy Fieri and his son Hunter in the Bahamas to experience local cuisine and explore what makes the waters around these islands the ideal “all-you-can-eat buffet” for a wide variety of shark species. SHARK TANK MEETS SHARK WEEK Wednesday, July 25 at 9 p.m. ET / 6 p.m. PT In SHARK TANK MEETS SHARK WEEK, Barbara Corcoran, Mark Cuban, Daymond John, and Kevin O’Leary of CTV’s SHARK TANK are paired with different oceanic organizations to learn about the issues that sharks face around the world – overfishing, bycatch, and habitat destruction. With this newfound knowledge, the stars return to the SHARK TANK studio with fellow shark Robert Herjavec to pitch each other on which organization deserves a grand prize donation of $50,000. Each shark will vote for the organization they feel deserves the money, with one catch – they can’t vote for their own pick.
