It's Donald Trump's favorite time of year: Shark Week!

That's right, the year's toothiest television lineup is back, this time for its 30th anniversary of showcasing the sea's gnarliest predators, and fans can expect a whopping 19 hours of new programming that's sure to take a bite out of those summer beach-going plans.

To prepare for all the gnashing action to come, here's what you need to know about this year's Shark Week lineup, from how to watch to the list of celebrities you can expect to see wading into the waters of this year's events to the segments you simply won't want to miss.

WHERE and WHEN to watch: Shark Week kicks off on Discovery starting Sunday, July 22 at 7 p.m. ET/PT with a look back at some of the best "Alien Sharks" before diving into an ocean of new original programming that'll air each and every night until next Sunday, July 29.

WHO is taking a swim: This year, there are tons of familiar faces braving the waters of Shark Week alongside the network's team of science experts, including the year's host Shaquille O'Neal, along with special guests like Shark Tank stars Mark Cuban, Barbara Corcoran, Kevin O'Leary, and Daymond John, athletes Ronda Rousey, Aaron Rodgers, Rob Gronkowski, and Lindsey Vonn, and reality TV hosts like Bear Grylls, Guy Fieri, and Ben Bailey.

O'Neal, for one, didn't quite know what he was getting himself into by signing up for Shark Week hosting duties, as he admitted in the announcement, "Full disclosure, I thought I was hosting Shaq Week. But that doesn't exist." Maybe next year?

WHAT meaty programming is ahead: The schedule for this year's Shark Week is packed with delicious treats, from Shaq's brave effort to dive in a shark cage (in which he, um, makes a new friend) to the Shark Tank team sinking some cash into a shark conservation project to a timely exploration of the history — and perhaps eventual return — of the legendary megalodon.

Here's a full look at Discovery's Shark Week schedule (all times ET/PT).

WEDNESDAY, July 25

8 p.m.: Megalodon: Fact vs. Fiction - If you're intrigued by that ominous poster for the movie Meg, well, this is the show for you.

9 p.m.: Bloodline: Spawn of Jaws - If Steven Spielberg's Jaws gave you pause about dipping toe in the ocean, there was good reason; places like Long Island, New York have long served as great white shark nurseries, and Dr. Craig O'Connell thinks it's because the bloodline that once terrorized the are is still alive and well.

10 p.m.: Great White Shark Babies - Experts Mauricio Hoyos, Michelle Jewell and Toby Daly-Engel are in search of shark pups off the coast of Baja. We'll have to wait and see how cute baby sharks are (no relation to that ultra-addictive kid's song, of course). (Editor's Pick!)
