Learn all about the gentle giants of the sea in this robotic traveling exhibition from WondeWorks at the Bishop Museum.

The exhibit, which opens at 9 a.m. today at Castle Hall, tells their 54-million-year-old story, from early life on land to their journey back to the sea. Life-size robotic whales illustrate the major categories of whale origins, adaptions and behavior from feeding and reproduction to swimming, vocalization, respiration, and diving. The exhibit will feature full-sized robotic versions of a Baby Gray whale, a Humpback whale and an Orca, and animated heads of a Northern Right whale and a Sperm whale.

On exhibit May 17 through Sept. 21. For more information visit www.bishopmuseum.org.
