Step into the open ocean with Tierney Thys

Marine biologist Tierney Thys asks the audience to step into the open ocean for a visit to the world of the Mola mola, or giant ocean sunfish. Basking, eating jellyfish, and getting massages, this behemoth offers clues to life in the open ocean — which accounts for 90 percent of the living space on this planet — and also shows how climate change may be affecting all life. (Recorded February 2003 in Monterey, CA. Duration: 16:53) Read Tierney Thys’s profile on TED.com
