"Here’s a short clip from the Smithsonian Channel‘s series “Hunt for the Super Predator.” It shows an encounter a team of photographers and scientists had with killer whales at Bremer Canyon off the coast of Western Australia. Using a special camera rig he designed, wildlife cameraman David Riggs shot some amazing underwater footage of killer whales that looks too good to be true (you can find it at 1:35 in the video)." - rønin
