The function of the Narwhal whale tusk revealed by a drone!

For some time now, there has been a new way of exploring the world, namely through the use of drones. These devices can go everywhere, are quiet and discreet and are equipped with the latest generation of state-of-the-art cameras.

Thanks to their use, it has been possible to film natural scenes never before captured on film. For example, this drone discovered a school of narwhal whales in the ocean and now finally we have managed to discover the true function of the long tusk on the side of their heads! 

So what is it for? The long tusk creates eddies of water in which to trap their prey, thus making it possible to catch them more easily!
