Narrated by former US President Barack Obama, this awe-inspiring natural-history series takes viewers on an epic 75,000-mile journey to explore life under the water – from cuttlefish and turtles to beluga whales and orcas.

With the five episodes dedicated to each of the five oceans – Atlantic, Pacific, Indian, Southern, and Arctic – cutting-edge camera technology gets up close to more than 1,000 ocean-dwelling species and captures behaviours that haven’t been caught on film before – including an octopus using its body as a gun to fire rocks at predators.
