Experts have investigated a string of non-deadly killer whale attacks that have occurred in Spain and Portugal over the last few months. There have been multiple reports of sailors being rammed by orcas or being chased by sea animals, and even a number of reports of mammals sinking ships during the last three years.
The Mirror reports that April Boyes, a British sailor, recalled how a boat trip turned into a nightmare after orcas continuously rammed into the vessel for over an hour. On This Morning, the sailor with five years of experience described the orcas' movements as "a bit of a headbutt". She noted that they weren't worried until water began gushing in.
However, according to marine biologist Renaud de Stephanis, the orcas were likely pursuing a "massive adrenaline rush", adding that it was "just a game for them." You can get more story updates straight to your inbox by subscribing to our newsletters here.
