Sharkfest is swimming closer. National Geographic’s fishy celebration starts this month, and the full lineup reveals hours and hours of new programming.

Nat Geo’s Sharkfest (not to be confused with Discovery Channel’s Shark Week) will air over five weeks on two networks with 17 new programs premiering. The event starts on Sunday, July 19.

The 8th annual Sharkfest will start off on National Geographic for three weeks before moving to Nat Geo WILD on Aug. 9 for the final two weeks. Fin-tastic programming kicks off at 6 p.m. EDT with specials from the archives while new segments debut at 8 p.m. EDT most nights.
