Orcas Ramming Boats off Spanish Coast: Play Behavior or Revenge?

Killer whales have been attacking boats and ripping off rudders near southern Spain.
Experts believe the orcas are playing, not purposefully attacking the boats.
The orcas may have targeted sailboats because they find them exciting to interact with.
One theory suggests a female orca named White Gladis has been teaching other whales to attack boats in retaliation for human actions.
While the orcas' behavior seems playful, it could endanger both humans and the whales.
