The Terrifying Intelligence of Killer Whales

Feb 12, 2026
Orcas have been studied for decades, yet they continue to surprise us in unexpected ways. From culture and communication to emotion, cooperation, and tool use, this video explores why killer whale intelligence isn’t terrifying because it’s dangerous, but because it’s far closer to ours than most people realize.

Hope you enjoyed it! If you did I would highly appreciate a like on the video.
