Port and Starboard, the orca pair that were first observed predating great white sharks in 2017, were recently found to have killed as many as 17 sharks in a single day, according to researchers at Marine Dynamics.

The orcas, known to have preyed on several different species of shark in South Africa, were tracked offshore at Pearly Beach, near Gansbaai, by a team of scientists on board a Marine Dynamics vessel.
‘We observed the two orcas repeatedly diving down in a small area for almost two hours before they departed offshore,’ said Marine Dynamics researcher, Ralph Watson, in a post on group’s Facebook page.
The following Tuesday, eleven deceased Broad nose seven-gill shark carcasses were retrieved from the same beach by Watson and the MDA team.
