Two kayakers paused to take a closer look at some whales off the coast of Argentina, but got an unexpected surprise when one of the giant creatures lifted their boat onto his back.
This footage shows the whale roll over before moving slowly under the kayak and then lifting it clean out of the water close to the coastal city of Puerto Madryn.
The two very surprised humans on its back are taken along for the ride, but manage to keep their cool.
