Horse
Equus caballus
Quick answer
The horse is a large domesticated mammal kept for riding, sport, work, and companionship for thousands of years. Horses are powerful herbivores that can stand and run within hours of birth, communicate through body language and ear position, and typically live 25 to 30 years. They were first domesticated on the grasslands of Central Asia.

Built to run
Horses are prey animals built for speed and endurance. Foals can stand and run within hours of birth, an adaptation for escaping predators on open grassland. Their large eyes give them nearly 350-degree vision, and they sleep both lying down and standing up thanks to a locking mechanism in their legs.
Communication and intelligence
Horses are intelligent, social herd animals that communicate through subtle body language, especially the position of the ears, head, and tail. They form strong bonds, recognize individual people and horses, and can read human emotions, which is part of why they are used in therapy and equine-assisted programs.
Horses and humans
Domesticated on the steppes of Central Asia around 5,500 years ago, horses transformed travel, farming, trade, and warfare. Today they are kept mainly for riding, racing, sport, and companionship, with hundreds of breeds ranging from tiny ponies to massive draft horses.
Care and health
Horses need plenty of forage, fresh water, regular hoof care, and room to move. Their digestive system is designed for grazing little and often, so sudden diet changes can cause serious problems such as colic. Good dental and hoof care are central to a long, healthy life.
Frequently asked questions about the Horse
How long do horses live?
Most horses live 25 to 30 years, and some reach their forties with good care. Ponies often live even longer than full-sized horses.
How fast can a horse run?
A galloping horse averages around 40 to 48 km/h (25 to 30 mph), but quarter horses have been clocked sprinting at up to about 88 km/h (55 mph) over short distances.
Do horses sleep standing up?
Horses can doze standing up thanks to a stay apparatus that locks their legs, but they must lie down to reach deep REM sleep. They only need a few hours of sleep a day, taken in short stretches.
Where were horses first domesticated?
Horses were first domesticated around 5,500 years ago on the grassland steppes of Central Asia, in the region of modern Kazakhstan and southern Russia.
Can horses see color?
Horses can see some color but not the full range humans do. They distinguish blues and yellows well but have trouble telling reds and greens apart, similar to red-green color blindness.
