As the host of Discovery Channel’s Shark After Dark, Eli Roth knows a thing or two about sharks.

But one surprising fact about the ocean’s apex predators? They don’t like bubbles.

“The biggest misconception about sharks is that they are genuinely interested in attacking and eating people,” says Roth.

“When they see humans underwater we are very large so we’re almost their size. They’re curious and they want to know what we are about, but as soon as you blow bubbles they swim away.”

Roth spent a week diving in Tahiti for this year’s Shark Week and if anything, he only wanted them to come closer!

“They are very shy, very sweet and they are beautiful creatures,” he says.

And he’s passionate about educating others on the important role sharks play in our oceans.

“The function of shark is to cull the ocean of sick, dying and diseased fish,” he says. “There are a lot of fish down there and they are not going after the live fish. They are only interested in the dead ones.”

Roth returns as host of Shark Week‘s hit late-night talk show Shark After Dark for a second year in a row starting June 26 at 11 p.m. ET on Discovery.

“The truth about sharks is that they are endangered and it s up to us to protect them.”

Shark Week returns to Discovery Channel with all-new compelling shark stories Sunday, June 26 to Sunday, July 3.
