A video that has gone viral on social media shows an Eden's whale's unique feeding strategy. The drone footage, captured in the Gulf of Thailand, shows how the whale manages to trap fish in its mouth in behaviour that experts have called "extraordinary". According to the Smithsonian Museum's educational website, Eden's whales (currently the subspecies Balaenoptera edeni edeni) only live along the coast in Indo-Pacific waters and can grow up to 38 feet in length.

In this footage - part of an episode on the BBC documentary 'A Perfect Planet' - a huge Eden's whale is seen treading water and keeping its mouth open to create a flow that pulls fish into its mouth. Posted online by wildlife filmmaker Bertie Gregory, the clip shows a number of fish disappearing into the whale's mouth.

"By treading water and keeping the corners of their mouth below the surface, a flow is created pulling the fish into the whale's mouth. In the panic, some of the fish also seem to jump out the water and into the whale's mouth!" Mr Gregory while sharing the video on Instagram last week, where it has been viewed over 8 lakh times. The video also made its way to other social media platforms, leaving millions on viewers stunned. On Twitter, it has racked up nearly 4 million views. You can watch video below:
