Now, Canadian researchers have filmed incredible video footage in the high Arctic showing the real purpose of  their tusks; feeding. This short documentary highlights four researchers from Fisheries and Oceans Canada describing how they were able to capture the never before recorded evidence of this narwhal behavior. Fascinating!
