This was the moment two killer whales did battle in front of a boat full of tourists.

The clip, filmed February 15, shows the two whales wrestling each other in the middle of Mossel Bay.

Tour guide Ewan Wilson told Newsflare: “Two killer whales where spotted wrestling each other in front of a lucky tourist boat. The epic conflict left the tourists silent as they watched these beautiful and slightly terrifying animals in battle.”

It is not known why the animals were fighting.
