  • A pair of orca whales in South Africa killed 17 sharks in just "one sitting," said marine biologists.
  • An Orca duo was spotted ripped-open sevengill sharks to eat their oil-rich livers.
  • The male duo had previously terrorized great white sharks that used to hunt in the area.

An infamous pair of adult male orca whales in South Africa killed 17 sharks in "one sitting," according to marine biologists.

The team at Marine Dynamics Conservation Trust has been tracking the two whales, named Port and Starboard, who are known to prey on several species of sharks. 

They found the orcas "repeatedly diving down in a small area for almost two hours before they departed offshore."
