The Discovery Channel is once again using its popular Shark Week to promote species and habitat conservation by partnering with environmental organization Oceana.

The 24th season, which kicks off July 31, will feature a nightly PSA by Oceana encouraging viewers to learn more about their Save Our Sharks campaign and support legislation protecting the vulnerable species.

“This year, Discovery’s Shark Week is especially important as we are finding more and more opportunities to win protections for sharks all over the world,” said Andrew F. Sharpless, CEO of Oceana. “Oceana has already won two big victories for sharks this year: in January, the U.S. Shark Conservation Act became law, and just this month, Chile joined a growing list of countries to ban shark finning. With Discovery’s help, we can put in place more protections for sharks around the world.”

As mentioned earlier, this year's razor-sharp festivities will be hosted by comedian Andy Samberg, aka chief shark officer. In an interview with Entertainment Weekly, the 32-year-old recalled how he became involved with the event saying, “It has very little to do with me on the surface, which to me was a perfect sign that I should do it. Everyone loves Shark Week. I love Shark Week. I was just so flattered. The pitch was that I would get to fly to the Bahamas and literally swim with sharks, and I was thinking there’s no way I would ever have the balls to do that on my own, so I went for it.”

Check out this hilarious promo clip below in which Samberg declares his hopes for the fate of the next chief shark officer.

Shark Week rocks out this Sunday at 9 p.m. on Discovery Channel.
