Researcher Daniele Cagnazzi described it to Business Insider Australia as "an incredible event." Fortunately, a camera was able to collect video of the rare sighting, which had only been observed in these dolphins once before. "The humpback dolphins were observed swimming a few metres away from and parallel to the shoreline. This behaviour probably allows dolphins to concentrate fish against the mud bank before charging at them at high speed," said Cagnazzi.
"On some occasions the fish were washed onto the shoreline by the wave of water associated with the dolphin's beaching, resulting in a full body exposed beaching."
Australian humpback dolphins aren't the only ones to use this remarkable foraging method. Both bottlenose dolphins and killer whales have also been known to strand-feed, often working in unison with their pods to push a school of fish ashore.
