Two children had the shock of their lives after finding themselves stranded in the middle of the sea - with two killer whales swimming directly towards them.
The youngsters were playing in the water together when they suddenly realised the rest of the swimmers making a run for it.
But they were too far away from land to safely make their way back to shore.
Instead, they had to watch in horror as two huge orcas made a beeline for them.
A video captures the sound of the children screaming in fear as they watch the giant mammals pick up speed, heading straight towards them.
