Great whites might think they're the top of the food chain, but orcas beg to differ.
In an amazing video shared by tour guide Donavan Smith, a great white was trapped by a two orcas, which Smith says in the video is hunting it.
PICS: Where are SA's great white sharks? Right here, says Marine Dynamics
It took place just off the coast of Knysna while Smith was giving a tour.
Orcas are known to target sharks - they like to munch on their livers - and the increased sightings of these killer whales in recent years is theorised to have led to a decrease in great white sightings in Cape Town's False Bay.
However, according to Marine Dynamics in Gansbaai the numbers have picked up again in the region.
