Alaskan politician Joe Miller uploaded this video to Youtube with the following caption:
In this extraordinary video filmed by my friend Dusty Harpole while he was out adventuring with Dave Keller this past week in Tutka Bay, Alaska, a mother otter avoids getting eaten by a group of killer whales by jumping on the back of Charlie Largent's small boat that was in the area. Unfortunately, she lost her baby in the daring escape. Other HD footage is available.
Warning: the ending may cause tears.
