The family Equidae is a group of hoofed mammals that includes horses, donkeys, and zebras. Members of this family are characterized by their single-toed hooves, long legs adapted for running, and herbivorous diet, primarily consisting of grasses. Equids are social animals, often forming herds or family groups with complex social hierarchies. They have highly developed senses, especially vision and hearing, which help them detect predators. Domestication of horses and donkeys has played a significant role in human history, providing transportation, labor, and companionship. Equidae species are found naturally in Africa, Asia, and parts of Europe, though domestic horses are now widespread worldwide.
