Life in the ocean doesn't always go swimmingly—not even for sharks. As 7 News reports, this video, captured by an amateur drone hobbyist, captures what experts think is a pod of false killer whales as they stalk and attack a juvenile shark off the east coast of Australia.

False killer whales—large members of the dolphin family, with some males reaching 20 feet in length—aren't normally spotted by humans in the area. You can watch the rare footage (above) as the four dolphins trail behind the shark before finally going in for the kill.
