Drone footage shows the mesmerizing patterns created by a giant bait-ball as two sea lions dart in and out attempting to catch a meal. The huge shoal of fish dances as the sea lion goes hunting – diving straight into the middle of the ball, sending the fish scattering. The shoal – which contained thousands of arripis trutta, known as Australian salmon – created hypnotic swirling patterns when viewed from above as they seek to evade the sea lions advances. British videographer Nick Holton, originally from Bristol, but now living in Sydney, captured the fascinating footage just after sunrise while out with his drone. After spotting a shadow in the ocean off the coast between Tamarama and Bronte, near Sydney, Australia, he sent his drone up to investigate.
