Bertie Gregory. Wave Washing Killer Whales.
A pod of B1 Antarctic killer whales preparing to ‘wave wash’ a weddell seal off a piece of sea ice and into the water so they can eat it. The bubbles are thought to be part of the way they communicate with each other to form these waves. Photographed using a drone from an ice strengthened sailboat during a month-long expedition to find this rarely seen behaviour in the Antarctic Peninsula, Antarctica.
