It's 2019 can we please stop the stupid?

Umm, no.

Both are referred to as dolphins.  Deal with it.

BTW - that difference isn't so different.
nomenclature
[ˈnōmənˌklāCHər]


NOUN

1. the devising or choosing of names for things, especially in a science or other discipline.
   "the Linnean system of zoological nomenclature" ·
   [more]
   
   • the body or system of names in a particular field.
     "the nomenclature of chemical compounds"
     
   • formal
     
     the term or terms applied to someone or something.
     

So? Still a huge difference between how laypeople name things and how scientists name and classify things.

I really don't like this trying to falsely equate the context here. How laypeople name things and how scientists name things are not the same context or "nomenclature".

Which are you?  

Are you a marine biologist now?
