The Big Blue
Journey to Australia?s southern ocean and uncover one of its best-kept secrets - a natural phenomenon called the ?Bonney Upwelling? that sparks a feeding frenzy all the way up the food chain to the planet?s largest living creature, the Blue Whale. With a heart the size of a Volkswagen, a tongue that weighs more than an elephant and a mouth big enough to capture 50 tonnes of sea water, a feeding Blue Whale is a sight to behold. Filmed in Hi Def, this documentary captures for the first time the extraordinary spectacle of this unique event.
