See, specifically, the sub-heading on Odontocetes — literally, "toothed whale".

You appear to be operating with the category that "whale" is wholly and exhaustively synonymous with "baleen whale". You're wrong.

From the same wikipedia article...

"They [whales] are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. "
