Nat Geo Wild’s “SharkFest” is megalodon-sizing to two weeks, doubling in length as a counter-programming move against rival Discovery Channel’s popular “Shark Week,” TheWrap has learned exclusively. Additionally, the sixth annual “Shark Fest” has also shifted up on the calendar to beat “Shark Week” to cable airwaves by a week, as opposed to going (hammer) head-to-head again.

“What’s better than one week of shark TV? TWO WEEKS OF ‘SHARKFEST,'” Geoff Daniels, executive vice president and general manager of Nat Geo Wild, told us in a statement. “We are literally jumping the shark this year by serving a supersized feeding frenzy of jaw-some shark specials, and by taking the first bite, we’re giving Nat Geo Wild viewers a bonus week of the shark shows they love. Why wait, when we need to inspire everyone to save our sharks now, more than ever? With so much ‘SharkFest,’ we’re gonna need a bigger network!”

Can’t wait for the whole feeding frenzy? Watch some poor seal get hunted by a great white in our exclusive SharkFest sneak peek clip, which is posted above.
