1000-strong pod of dolphins flees killer whales in South Africa
A tourist in South Africa has captured the incredible moment a huge pod of dolphins frantically fled a group of killer whales.
At first, the tourists had no idea why the "mega-pod" of around 1000 common dolphins was moving at such a furious pace past their boat.
Later, however, the dorsal fins of killer whales were spotted nearby.
The footage was captured last year but has only recently been posted online.
