If you haven’t been to the beach this summer, you may never get there after watching “Shark Week.”

The Discovery Channel franchise is back with deep dives into shark history, modern-day scares and terrifying true stories about near-death experiences. A solid week of programming begins Sunday night. Here are some of the highlights.

Sunday, July 28

“Expedition Unknown: Megalodon” (8 p.m.)

Five times bigger than a T. Rex, with jaws capable of crushing a tank, the Megalodon was the ultimate apex predator. This 60-ton mega-shark ruled the world’s oceans for nearly 20 million years. Then, suddenly, it vanished. So how did the king of the deep lose his throne? Paleontologists are using fossilized teeth — the only surviving evidence of the Megalodon — to take a bite out of the mystery of its disappearance.

“Shark Trip: Eat. Prey. Chum.” (9 p.m.)

Rob Riggle and a group of celebrity friends (Adam Devine, Anthony Anderson, Joel McHale, Damon Wayans Jr.) swim with the sharks in this entertainment special produced by Will Packer (“Girls Trip”).

Monday, July 29

“Sharks of the Badlands” (8 p.m.)

A record 150 white sharks were recorded off the coast of Cape Cod this year. For the first time in 80 years, a white shark attack turned fatal. Greg Skomal teams up with Andy Casagrande and shark expert Kina Scollay in New Zealand to test shark detection surveillance technology and hopefully bring it back to the US.

Tuesday, July 30

“Laws of Jaws: Dangerous Waters” (9 p.m.)

“Shark Week” hosts Paul de Gelder, Mike Dornellas, Nick Lebeouf, and Jamin Martinelli reenact five recent shark attacks to find out how things could have ended differently. What do you do if you’re surrounded by human or fish blood? Could the electronics we’re bringing into the water be triggering attacks? Our hosts will attempt to answer these questions and more as they stage the most daring shark experiments ever attempted. No cages are allowed.

Wednesday, July 31

“Capsized: Blood in the Water” (9 p.m.)

After a yacht bound for Florida capsizes during a storm, its crew drifts for days in the Atlantic where they become prey to a group of tiger sharks. With the hope of rescue dwindling, the crew must do everything in their power to survive as the sharks continue to hunt them.

Thursday, Aug. 1

“Monster Mako: Perfect Predator” (10 p.m.)

Joe Romeiro and Keith Poe share brand-new footage captured off the coast of California of rare Mako behaviors.

Friday, Aug. 2

“I Was Prey: Shark Week” (10 p.m.)

Leeanne Ericson was swimming in the Pacific Ocean when a Great White shark grabbed her leg and dragged her underwater. Far away off the northern coast of Hawaii, spearfisherman Braxton Rocha was ambushed by a Tiger Shark. This hour tracks how Ericson and Rocha fought to save their lives.
