Wild Names: Feral horses are known by different names across the world. In the American West, they're called mustangs; in Australia, they're known as brumbies; in Spain, they're called Sorraia.
American Extinction: Horses were once indigenous to North America. They died out at the end of the last Ice Age. It's unclear why, but it's possible they were hunted to extinction by newly-arrived humans.
Sleep Standing Up: Horses can sleep standing up or lying down; they sleep about 2½ hours a day in 15 minute increments. Horses must lie down to reach REM sleep every few days.
