Equine species primarily refer to members of the family Equidae, which includes horses, donkeys, and zebras. These animals are known for their long legs, strong bodies, and unique social behaviors. They are herbivores, primarily grazing on grasses, and have evolved to be fast runners, which helps them escape predators in the wild. Horses, one of the most well-known equine species, have been domesticated for thousands of years and are used for various purposes, including transportation, work, and recreation. Donkeys are often used as pack animals, while zebras are known for their distinctive black-and-white stripes and live in herds in the wild.
