Ten fun facts

  1. it rests its weight on a single toe, the middle one, while the other toes remain as tiny bony remnants called chestnuts.

  2. its ancestor Eohippus was no taller than twelve inches at the shoulder and had four toes in front and three behind.

  3. an adult male has forty teeth while a female has thirty-six, with the difference being the canine teeth, also called tushes.

  4. the stomach holds only four gallons while the cecum alone reaches nine gallons, meaning food rarely stops moving along.

  5. digestion in the stomach lasts about six hours, while digestion in the intestine can take up to three entire days.

  6. the bay coat, with a brown body and black mane and tail, is the ancestral color of the horse and the most common.

  7. hair from the tails of male horses is traditionally used to craft the fine bows used for playing violins.

  8. some horses have a visible white sclera around the iris, which is called a human eye and is typical of the Appaloosa.

  9. the horse became extinct in the Americas about ten thousand years ago and returned only with Christopher Columbus.

  10. the tarpan, the wild European horse, became extinct in nineteen hundred nine when the last individual died in a Russian zoo.

Try it yourself

Experiment 1

Fill a quart bottle with water and imagine fifteen lined up to match a horse's stomach capacity. Then imagine thirty-five to see how large its cecum is.

Experiment 2

Mark twelve inches on a tape measure to see the shoulder height of Eohippus. Then measure nearly seven feet to see the record height of Big Jake.

Experiment 3

Count your own teeth in front of a mirror and compare your total to the forty teeth of an adult male horse or thirty-six of a female.
