On: 52-hertz whale

They're still order cetacea though, which is then split into baleen whales and toothed whales, which is where dolphins and orcas are found.

But not all cetaceans are whales. If orca are whales, then so too are the other dolphins. "Whale" is really a lay term covering the really big aquatic mammals. A whale shark certainly isn't a whale, but the term is still used there in the common name because of the association with size. Flipper wasn't a whale.

That makes sense, thinking of the whale sharks.
