Why Don't Wild Orcas Kill People? 🐋 #orca #killerwhale #orcaattack #animalfacts

Orcas hunt great white sharks and even blue whales, the biggest animals that have ever lived. Yet there's no confirmed case of a wild orca killing a person. So why do the ocean's top predators leave us alone? Dot looks at the clues: family food traditions that orcas learn from their mothers, the way we probably sound to their echolocation, and their big, careful brains. Plus what changes in captivity, where orcas have killed people, and why the Southern Resident orcas need help today.
