California photographer Slater Moore captured drone footage of killer whales eating a live shark last Tuesday during a Monterey Bay Whale Watch tour, according to CBS News.
The Sea Wolf II, which had a dozen whale watchers on board, received a call from a fishing boat that said there were killer whales about 40 minutes away from their coordinates at the time.
The passengers weren't sure if they would make it in time, but when the Sea Wolf II arrived more than a half-dozen killer whales began swimming around the boat.
Moore then set up his drone and began filming the encounter, according to the Washington Post.
Moore said he tried to keep the drone steady and contain his excitement while filming an adult killer whale as it ate what appeared to be a sevengill shark.
He told the Washington Post that the whales appeared to pass the shark to one another.
"They kind of take turns," Moore explained to the Washington Post. "One grabs the shark. The other ones peel off and circle around."
Monterey Bay Whale Watch told CBS News that this type of food-sharing is rarely caught on film. They also noted that the adult whales may have been teaching the calves how to hunt for food.
Moore and Monterey Bay Whale Watch uploaded the video to social media and it has since been shared thousands of times.
