What's the proper name?

[Starlight]

I have some Goat's Weed Pepper seeds on my list to grow for this year, but when I googled to see what they looked like I see Goat's Weed aka Black Cobra.

There is not a lot of listings under Goat's Weed, but there sure is for Black Cobra.

Please, how should I name my pepper properly? Does anybody know why the aka? Sure is a whole lot of difference in the names. Goat and Cobra aren't even close.
