An expert has revealed the real reason why orcas are attacking boats and other sea animals in various viral videos.
There have even been a number of reports spanning over three years of the mammals sinking ships. Shedding light on the strange incidents is marine biologist Renaud de Stephanis who says the mammals were most likely pursuing "a massive adrenaline rush", reports The Mirror.
It comes a week after a boat was rammed by a killer whale off the Scottish coast in what is believed to be the first attack in UK waters. The boat had just set sail from Lerwick when an orca slammed into the stern and circled the boat before backing off.
