Narwal
Rarely has footage of fishing caused such a stir in the scientific community.
However, the aerial video of a pod of Narwhals using their long tusks, which has earned them the nickname Unicorn of the Sea, to knock some Arctic cod senseless and easier for consumption has drawn attention from around the globe.
"There's been a debate for 400 years about what those tusks are used for," said University of Windsor assistant biology professor Nigel Hussey, who was part of the team of researchers who shot the video using drones.
"It's an iconic animal because of what is essentially an erupted tooth. There's been many hypothesis, but no one has observed or proven anything specifically.
"This footage is the first time we have a direct observation of the tusk being used for a specific behaviour."
