This video has everything: Beautiful scenery, a cute otter, dramatic tension, and a happy ending. A guy on a boat off the coast of Alaska filmed a killer whale in hot pursuit of an otter that is literally swimming for its life.
When the otter gets to the boat it JUMPS onboard just in the nick of time. You can also see the massive whale waiting for the otter to get back in the water. The description on the video says the boat eventually got far enough away from the orca for the otter to swim off.
