Horse (Equus ferus caballus)

Equus ferus caballus is the domesticated subspecies of horse that is closely associated with humans. In general, horses are ungulates, or hooved animals, that possess one toe on each foot, and have superb balance. Humans have bred horses to perform specific tasks for thousands of years. There are over 300 horse breeds known today, but all of these breeds can typically be classified into two groups: heavy horses and light horses. Heavy horses, like the Clydesdale, are slow but strong - perfect for doing heavy farm work. Light horses, like the Thoroughbred, are bred for agility - perfect for racing. Plenty of other more intermediate breeds exist as well. They have been tamed since around 3000 B. C. Since then, the wild forms have mostly disappeared - with the exception of Equus ferus przewalskii.
