Horses are a group of animals of the family Equidae. They are herbivores, which means they eat grass and other plants. Some plants are dangerous for them, like ragwort, lemongrass (oil grass) and sometimes acorns.

The standard horse is the species Equus caballus. It was domesticated from wild horses by humans at least 5000 years ago. They are large, strong animals and some breeds are used to pull heavy loads. Racehorses can gallop up to 30 miles an hour.

A male horse is a stallion, and a female horse is a mare, while the general term for a young horse is a foal. A young female horse is a filly, and a young male horse is a colt. A castrated horse is a gelding. Horses have hooves which sometimes have protection called horseshoes from hard or rough ground.

A horse is related to the rhino and tapir in the order Perissodactyla.
