Nat Geo & Nat Geo WILD Expand SharkFest

National Geographic and Nat Geo WILD’s SharkFest is returning this summer for an expanded seventh run that is set to air for three weeks across both networks.

The first week launches on Nat Geo beginning Sunday, July 14, while Nat Geo WILD takes the following two weeks from July 21 to August 2. SharkFest is slated to feature a wide variety of programming about the animals, from the latest developments in shark research and preservation to new ways to predict shark attacks.

World’s Biggest Great White?, which will be simulcast on both networks on Sunday, July 21, at 8 p.m., documents the re-emergence of what is thought to be the largest great white shark ever filmed. Nicknamed “Deep Blue” for her arrival and rapid departure, this great white shark, estimated to be 20 feet long and almost two and half tons, has not been captured on camera in more than five years.

Other SharkFest highlights include an experiment to determine if the weather can help predict shark attacks in Forecast: Shark Attack and the ultimate battle for dominance in Cannibal Sharks. Great Shark Chow Down, meanwhile, features footage of sharks feasting, and Man vs. Shark joins marine biologist Jeremiah Sullivan, who has been developing an armored suit to go nose to nose with sharks to help with their preservation.

SharkFest aims to raise awareness about ocean health. As part of Nat Geo’s recently launched “Planet or Plastic?” initiative, PSAs will run across both networks throughout the three weeks, encouraging viewers to not only learn more about the plastic pollution crisis but take their own plastic-free pledge.

“Nat Geo and Nat Geo WILD are diving in head first with this year’s feeding frenzy of shark content,” said Geoff Daniels, executive VP of global unscripted entertainment at National Geographic. “SharkFest continues to blow its competition out of the water, growing every year with jaw-dropping, science-first shows that are so unique and compelling that viewers will be totally enthralled, night after night after…night—and this year we’re thrilled to announce our exclusive access to the greatest, most buzzworthy shark superstar in history, Deep Blue.”
