Killer whales have allegedly been taught how to sink yachts off Gibraltar by a female orca named White Gladis, who is believed to be seeking revenge after experiencing trauma from a boat collision or entanglement in illegal fishing nets.
A vengeful killer whale called Gladis is teaching gangs of orcas to attack yachts around Gibraltar, and has already struck three boats - sinking two of them.
It may read like something out of Moby Dick, but in this case the truth is stranger than fiction....
