Do You Know Your Antelope?

When I think of antelopes, the first thing that comes to mind are their extravagant horns, often curving into beautiful shapes like arcs and helices. Can you recognize any of these unique-looking hoofed, horned creatures? Originally I was gonna ask you to match the name to the antelope pictured but, because even I am not an absolute antelope expert, I decided to make it easier on both of us. For each, you'll see a picture, a description of a trademark feature, and part of the species name (think Wheel of Fortune) – it's up to you to complete the word! Good luck.
