How can the largest creatures on the planet survive by almost exclusively eating some of the smallest creatures in the sea? In this video from Oregon State University, we get a very rare look at how blue whales eat tiny crustaceans called krill, and how the whales decide if a given krill swarm is worth lunging for. A research drone provides the bird’s-eye view while marine ecologist Leigh Torres narrates.

Next: Whales swim with a paddleboarder off the coast of Esperance, a seal herds fish off the coast of Australia’s Bondi Beach, and drones help scientists study Guatemalan volcanoes.
