Open Ocean
Season 1, Episode 3 of 8
A void. Endless blue stretches in every direction. The sea bed is a staggering eight kilometres deeper down and the nearest island is 500 kilometres away. There is nothing save the burning sun above and the blackened abyss below. How, then, does life exist? Finding the only shelter under floating matter, half-moon fish pick off parasites from the bizarre three-metre-long sun-fish; loggerhead turtles pause to nibble particles on a log; huge schools of sardine, yellow-tails and trigger-fish bring the number sheltering under the flotsam to their thousands.
