Who is the host of Shark Week 2019? Unofficially, it's Rob Riggle.

In previous years, Discovery has announced one official host for the entire duration of Shark Week festivities. In 2018, Shaquille O'Neal had the honor, and Rob Riggle joined him on a shark expedition. 

For Shark Week 2019, Rob is hosting Shark After Dark, a nightly roundup of Shark Week's most awesome moments. He'll be joined by celebrity guests and shark experts throughout the week. 

Rob is also featured prominently in Shark Week 2019 promos. He's officially just hosting Shark After Dark, though, and not the entirety of Shark Week's programming.

He also spent more than 20 years in the United States Marines. 

According to, Rob served for nine years on active duty before going into the reserves. He became a public affairs officer and was usually attached to Command Elements. His initial military ambition was to be a pilot, but he ultimately left flight school to pursue comedy.

"I went through officer's candidate school, went through flight school and the further I got along, the more I realized if I continue flying I'm not gonna be able to pursue my dream of comedy and acting," he said in an interview with

"So I stopped flying, became a ground officer, had a short contract, fulfilled my contract, and pursued comedy and acting. I stayed in the reserves though and did the reserves for the last 14 years... This is a great country, you can do it all."

Why are some people upset about Rob Riggle bringing his celebrity pals to Shark Week?

Everyone seems to agree that Rob himself brings a great dynamic to Discovery, but many people think sharks — not celebrities — should remain the stars of Shark Week 2019.

A viewer named Jen Hawkins tweeted, "For the past couple of years, Shark Week has been less educational and more 'Look how many C-list celebrities we can get to act stupid around sharks.'"

Twitter user @0ffthe_Chaney seemed to agree, writing, "Shark week is so disappointing, why are they highlighting celebrities instead of showcasing all the amazing marine scientists out there putting in hard work?! Also, if they could stop calling sharks 'monsters' that would be great too."

We wonder what the sharks think of all this! Shark Week 2019 runs through August 4 on the Discovery Channel.
