The world’s highest paid actor slipped into a wetsuit, strapped on a scuba tank and swam with the fishes inside the new aquarium’s 1.5 million-gallon tank on Wednesday. Making it even weirder: ex-Presidents Jimmy Carter and George W. Bush were there to look on. The famous trio were joined by other celebrities like Kevin Costner, Easton Corbin and even Secretary of the Interior Ryan Zinke for the grand opening of the Wonders of Wildlife National Museum and Aquarium in Springfield, MO, according to the Kansas City Star.

After taking a dive in the Shipwreck Tank, Wahlberg spoke to reporters about the importance of conservationism and how pleased he was with the new museum and aquarium, according to local outlet KY3.
