The Mysterious Phenomenon of Killer Whales Attacking Boats.

A pod of around 20 killer whales attacked a ship off the south coast of Spain, marking the second such incident in the region this month. Researchers believe the attacks may be driven by a single, revenge-bent female, which has taught the other orcas to follow suit. The orcas may be engaging in an unusual sort of playful behavior or defensive behavior based on trauma. Conservationists have called for continued protection of the pod and the species while managing interactions in a way that does not cause harm to humans or the whales.
