The Smithsonian Networks present an unparalleled, crystal-clear look at some very grand yet gentle giants of the sea. With high-definition cameras aimed squarely at a special location off the coast of Australia, this informative production offers a full scope on the majestic and endangered blue whale. As much as 100 feet long, weighing up to 180 tons, with a heart the size of a Volkswagen and a tongue that weighs more than an elephant, the Blue Whale is a sight to behold.

Join Smithsonian Networks as HD cameras capture the planet’s largest living creature having a feeding frenzy. Also includes the bonus feature Footprints on the Water: The Nan Hauser Story, which follows the personal quest and groundbreaking work of this American conservationist as she journeys to some of the last unspoiled places on earth on a mission to unravel new clues to the behavior of whales and dolphins.
