Horses, zebras, donkeys and asses all belong to the Family Equidae, a group that is also referred to as equids. Equids are beautiful, graceful mammals that possess grace, speed, and endurance which enables them to flee from predators.
Equids inhabit the desert and grasslands of Asia and Africa but have been introduced to many areas around the world. All species of equids feed primarily on grass, and possess acute senses of sight and hearing.
The domesticated horse is descended from the wild horse. Domesticated horses are the most common equids today.
Equids form herds that consist of extended family groups. These herds cover large areas and individuals communicate to other herd members using mouth gestures, ear movements, vocalizations, and tail movements.
Domesticated horses have had a long shared history with people, and have contributed greatly to the advances of civilization. At war or peace horses have served mankind for thousands of years.
