Drone video posted online shows a rare sight: killer whales feasting on a shark in California's Monterey Bay.

The photographer, hired by Monterey Bay Whale Watch, said there were at least 25 whales feeding on a Sevengill shark during the recent whale watching trip.

One whale can be seen thrashing the white shark in its mouth before leaving it for another whale to pick up. At other points, the whales are seen gliding and rolling through the water.

The video was posted on Dec. 13 by Slater Moore Photography on Facebook, and was viewed nearly 500,000 times and shared more than 1,300 times.
