A new 3-D IMAX film features humpback whales traveling around the world, showing how the marine mammals communicate, feed and care for their young.
Narrated by actor Ewan MacGregor and produced by nature documentary filmmakers MacGillivray Freeman Films, "Humpback Whales" opens nationwide Friday, Feb. 13.
Humpback whales (Megaptera novaeangliae) were hunted to near extinction half a century ago. The film delves into their recovery -- the whales are currently classified as "endangered" on the International Union for Conservation of Nature's (IUCN) Red List of threatened species -- as researchers study the massive sea mammals in Alaska, Hawaii and Tonga.
The whales can weigh as much as 50 tons and grow nearly 60 feet long. And they're fantastically accurate navigators, sometimes traveling 10,000 miles round-trip in a nearly straight line.
