Won't someone think of the yachters. - Lemmy.World

Fun fact: orcas are not whales. The name “killer whale” is a reversal of their previous name, “whale killers”. They’re just mean dolphins.
They normally aren’t mean. Orcas used to hunt whales with us. We would give them all the stuff we didn’t want, and they’d herd whale pods to the ships.
They’re mean to seals.
Well they eat everything, except us.
I really meant badass, but they can definitely be mean. All intelligent animals have a mean side.
Dolphins are mean dolphins.
*Orcas are nice dolphins
Dolphins are whales
I’ve never seen a convincing source for this factoid. As best I can tell, “killer whale” was never “whale killer” in recorded written text.

“Orcas were given the name ‘killer whale’ by ancient sailors’ observations of groups of orcas hunting and preying on larger whale species. They called orcas ballena asesina, or ‘killer whale.’ Their Latin name, Orcinus orca, also reflects this observation of orcas feeding on large whales. Orcinus translates to ‘of the kingdom of the dead,’ and orca refers to a kind of whale.”

So seems like this etymology makes more sense.
