It's 2019 can we please stop the stupid?

That's fair, though when biologists are doing their research, they are expected to use the scientific names for these organisms rather than ambiguous common names.

I don’t think they find the common name ambiguous. None of us actually do. I also don’t think they’re out to sea on research vessels speaking Latin to each other. Furthermore, the Latin name is usually included next to the common name as a parenthetical in research papers, an afterthought for clarity. It’s not like they all wander around correcting each other when everyone knows what dolphin means, even if it’s more fun to rile Brian than admit it.

Wrong. Many words are regional and Dolphin is one of them. I wasn't kidding when I said it is commonly used to refer to Mahi in the south-eastern United States. I wasn't kidding about "dolphin sandwiches" being on the menu in restaurants all over Florida. I doubt you'll see it anywhere outside the SE but in that region, Dolphin = Mahi.
