We spend a lot of time tonight gliding through the open ocean with sea-going predators. David Attenborough reminds us that the ocean is big and empty, “a vast blue desert” where finding food means travelling great distances and “there’s never an easy meal”.
But amid the big blue, the Hunt’s cameras have managed to track down the emperor of the oceans himself, a blue whale. We get up wonderfully close as one cruises by and feeds – rarely filmed from underwater and probably never this beautifully. The images are breathtaking, and Attenborough supplies a great detail about how the creature is so big that opening its mouth isn’t worth the effort unless there’s a lot of food to hoover up: it needs to average four tons a day.
Also worth looking out for are the beroe jellyfish, which prey on other jellyfish and look like very beautiful alien spacecraft.
Examining the hunting methods of aquatic predators. The vastness of oceans means that wildlife is scattered over a large area, and animals often have to travel great distances in search of food. Blue whales' great size proves useful in their search for krill, while frigate birds have developed a clever means of catching food without having to land on water. Also featuring footage of sharks, sea lions, spinner dolphins, albatross and sargassum fish.
