Horse

Equus ferus | Equus caballus

Horses are hoofed mammals in the genus Equus (family Equidae). The domestic horse is typically classified as Equus caballus. “Wild” horses can refer to the now-extinct wild ancestors/relatives of domestic horses—and the best-known surviving “wild-type” lineage is Przewalski’s horse (often treated as Equus ferus przewalskii or Equus caballus przewalskii), native to Mongolia and sometimes described as the last surviving wild horse form. The European tarpan is an extinct wild horse form that persisted into historic times but became extinct in the early 20th century, with late survivors likely interbreeding with domestic horses. Przewalski’s horse went extinct in the wild by the mid‑20th century, but captive breeding and reintroduction efforts have restored free-ranging populations, and it is listed by the IUCN as Endangered. Ponies are domestic horses that fall into a smaller size category, not a separate species.
