Canadian scientific footage confirms use of Narwhal Tusk
For the first time, there is video evidence of Narwhals using their tusks to hit and stun fish prior to eating them.
In collaboration with the community of Pond Inlet and benefiting from Inuit Traditional Knowledge, this first-of-its kind footage was captured by Canadian scientists from Fisheries and Oceans Canada (DFO), the University of Windsor, World Wildlife Fund Canada, the Vancouver Aquarium, and by Arctic Bear Productions.
There is a wealth of Inuit Traditional Knowledge and scientific theory about the uses of the Narwhal’s tusk, but prior to this there has been no definitive recorded scientific evidence of its use. While the scientists believe the primary function of the tusk is probably related to sexual selection, this provides new insights into the function of the tusk, raises new, interesting questions about the species, and opens new avenues of research into these iconic marine mammals.
The video footage was captured during another DFO pilot project, which was using an unmanned aerial vehicle (UAV or drone) to study Narwhal behaviour on their summering ground in Tremblay Sound, NU. This research also underlines the potential of UAVs for making scientific advances in observing and understanding wild animals.
