A valley killer whale named Gladis leads Orca gangs to fight with yachts around Gibraltar and has already sunk three boats in Europe.
It may read like something from Moby Dick, but in this case the truth is more strange than Herman Melvilles Fictional story of the white whale.
researchers assume that a female orca called White Gladis will be wild on revenge after being traumatized by a collision with a boat or was caught in illegal fishing nets.
gladis' attacks are now imitated by the rest of the sword walks population, which her rugged leader learned how to ram ships.
"Critical moment of agony"
"This traumatized Orca triggered this behavior of physical contact with the boat," said Alfredo López Fernandez, biologist at the University of Aveiro in Portugal and representative of the Atlantic Orca working group.
This "critical moment of agony" made Gladis aggressively boat, and this aggressive behavior is now copied by other orcas, which are social animals and can learn from each other, he told Wordsidekick.com.
On May 2, six of the Apex predators bounced into the fuselage of the Bavaria 46, who was traveling in the street of Gibraltar near Tanger in Morocco.
