It's back. Shark Week 2019 on Discovery starts Sunday, July 28, and it's sure to be, well, shark-filled. Discovery is planning more than 20 hours of new Shark Week programming, hosted by comedian Rob Riggle.
Here are the best shows, specials and more you should watch every night of Shark Week 2019, which runs through Aug. 4.
"Expedition Unknown: Megalodon." Sunday, July 28, 8 p.m. EST. Everyone's heard of the megalodon — a massive shark, now extinct — that lived as much as 3.6 million years ago. TV host Josh Gates heads to Mexico and South Africa to search for fossilized teeth of the massive predator.
"Shark Trip: Eat Prey Chum." Sunday, July 28, 9 p.m. EST. The 121-minute special features comedian Rob Riggle, who is planning a "guys trip" for his friends and fellow comedians. Adam DeVine, Anthony Anderson, Joel McHale and Damon Wayans Jr. But there's a catch — according to Discovery, the "guys trip" is actually a mission to locate the largest tiger shark in the Caribbean. Who knew Shark Week could be so funny?
"Legend of Deep Blue." Monday, July 29, 9 p.m. EST. Divers are headed for Guadalupe Island, a volcanic island off the coast of Mexico's Baja California Peninsula, in search of "Deep Blue," believed to be the largest great white shark ever spotted.

Scientists say Norfolk Island, a tiny Australian island in the Pacific Ocean, has some of the largest tiger sharks on earth, who are attracted to the area by full-sized animal carcasses locals toss into the sea.
