Explore the depths of the ocean off the coast of British Columbia with Phil Nuytten, a pioneer in deep sea exploration. Once thought to be barren, this stretch of water is home to an animal believed to be extinct: the glass sponge. On his journey, Nuytten explores a 20 mile long reef filled with glass sponges. At nine thousand years old, glass sponges are the oldest organisms on earth. It is even possible that glass sponges gave rise to all other multi-celled organisms!
