5 Interesting facts about horses

We all probably know a fair bit about horses. Here are some interesting facts about horses to increase the knowledge banks.

  1. The earliest known member of the horse family was the Eohippus, dating back 55million years ago. The closest living relative to a horse now, besides donkeys and zebras, is the tapir and the rhinoceros.
  2. Horses need to consume between 20 – 60 litres of water daily. A broodmare will consume up to 75litres in a day.

3. Horses cannot breathe through their mouths. The epiglottis rests above the soft palate while the horse is not swallowing, which forms an airtight seal. They are known as obligate nasal breathers and can only breathe through their nostrils.

4. A horse has vision of approximately 300 degrees. They have both monocular and binocular vision and each eye sees independently. Horses can see certain colours. They can see the blue and green colours of the spectrum but cannot distinguish red as they have dichromatic vision. They have bigger eyes than any other land mammal.

  1. Horses hearing range is 55 – 33,500 hertz (cycles per second), much greater than human hearing which is in the range 30 – 19000 hertz. The top range of hearing for a horse is higher, and they may hear things, that a human cannot, which explains a lot of “spooking” scenarios! Horses have 10 ear muscles to capture all those sounds.
