What’s a swimming down in the deep ocean?

Have you ever experienced that moment where you’re playing in the ocean and go to stand up, only to find the seafloor has completely dropped away from you?

What lies in the deeper depths of the world’s waters has always held an immense fascination for humankind, going back as far as the 4th century BC where—as Aristotle noted—divers would submerge with diving bells, ‘letting down a cauldron, for this does not fill with water, but retains the air’. Yet it wasn’t until 1960 that two humans, Jacques Piccard and Lieutenant Don Walsh, managed to reach the very bottom of the deepest known point in the ocean, Challenger Deep (10,911 metres down, some 6.8 miles) in the bathyscaphe Trieste.

Perhaps the most amazing thing about that journey? Small flounder-like fish were discovered lying on the seabed, surviving with ease the incredible pressure found this far down, a force that would have completely crushed an unprotected human. Oceanic wildlife is incredible in its ingenuity, and in the mystery that still shrouds many of these underwater species. So for this weekend’s viewing we’re recommending a selection of intense sea-going documentaries—all available on-demand via our video streaming app—for an amazing insight into what’s swimming in the sea beneath your feet, all those miles down.
