Antarctica’s ‘great secret’ exposed as cameras catch ‘strange creatures’ below ice

While exposing some of the animals that call this frozen desert home, the crew also set cameras up below the ice of the Southern Ocean, too, exposing waters teeming with marine life.

Sir David said: “Winter is coming and Antarctica now undergoes a major transformation, every day, 40,000 more square miles of sea freeze over and by the end of winter, the continent has doubled in size.

“This is by far the largest desert in the world, but the frozen surface at sea hides a great secret.

“It may be hostile above the ice, but below it, conditions are so stable that life over millennia has had time to diversify.
