Sea unicorn goes north as Arctic warms
- The sighting was made by the four-month North Pole-2015 expedition on a drifting ice floe which began one degree from the pole. The 17 scientists and two dogs drifted 700 kilometres through Arctic waters. Unexpected for the scientists was the discovery of the Narwhal - which has been called the Unicorn of the Sea - in such northerly waters. Zoologist Vladimir Tushkevitch said it was a 'real scientific discovery' because until now such whales do not generally appear above the 82 degrees of latitude.
