Pronghorn Antelope
Speed: Around 60 to 65 MPH
Pronghorn Antelopes are mostly located in North America. A little bit of house-cleaning needs to be done first on them, however. They are not actually antelopes, as they technically belong to the Artiodactyl species. Pretty much, this species involves anything with hoofs that bear weight equally on two of their five toes. There are both even and odd versions of this. Within that species is the Giraffoidea, which the Pronghorn officially belongs to along with the Okapi & Giraffe. However, due to looking so much like antelope, North Americans adopted the term and used it to describe them.
Therefore, it is mostly a colloquial use of the term. That said, their speed is quite impressive as they are among the fastest animals in North America. While the species travels in mixed herds during the winter, or basically their mating season, they break up where males form bachelor herds. Some even pop up to help defend all-female herds too. Females are actually the most aggressive and dominant of the species. Yet males are the fastest, moving upwards of 55 to 65 mph. Females tend to move between 40 and 50 mph on average.
