pronghorn

This term refers specifically to the Antilocapra americana, which is often mistakenly called an antelope. While it resembles a true antelope, it is the sole member of its own family, Antilocapridae, making it a distinct evolutionary lineage native to North America.

In a biological or conservation context, the word carries a connotation of extreme speed and agility. It is typically used in scientific descriptions of prairie ecosystems or in wildlife management discussions regarding the Great Plains.
