(OCEANS/SHARKS/ANIMAL VIDEOS) In celebration of Shark Awareness Day and the countdown to SharkFest on Nat Geo WILD and Shark Week on Discovery (beginning Sun, July 23), watch legendary National Geographic photojournalist Brian Skerry photograph sharks underwater as he discusses his mission to change the public’s negative perception of them. While it’s peak shark season and we’re hearing stories left and right of shark sightings and attacks, it’s important to remember that sharks are not our enemies, but they are actually integral to the ecosystem. Despite this fact, an estimated 100 million sharks are killed by humans each year, and 64 shark species are currently listed as endangered.

To learn more about Skerry and his shark PR campaign, watch special Mission Critical: Sharks Under Attack, premiering on Nat Geo WILD on Monday, July 24 at 10/9c. — Global Animal
