Forum:KB:Horned species confusion

Is there a good way to tell the difference between Dathomirian, Zabrak and perhaps other similar species with horns? I'm trying to be sure of the species on Cronah and Cyrus from the Jedi Academy books. If you go into this here and you look at the pages available for browsing (you have to be signed in to see all of the ones available), on the second and third pages you'll see one of them sitting on the far right on the second page and the other sitting third from the upper left, same species as the teacher Mr. Garfield on the far left. (I'll check the book later and make sure of which one is which.) ProfessorTofty (talk) 14:21, September 29, 2014 (UTC)
