A last refuge for Europe's blighted killer whales

[Gerald]

Europe's killer whales marvelled in the BBC's Blue Planet II series but these animals face extinction. Chris Gibson travelled to the small Norwegian island of Kvaløya where the orcas retain a strong foothold. But for how much longer?
It was one of those television moments. The sight of killer whales herding shoals of herring into tighter and tighter balls to trap the prey near the surface of the water.
