The second picture in the above series shows a Shetland pony. Compare its size with the height of our friend's, Irma Alarcon. To be considered a pony, a horse must be under 154 cm (57 in) in height.

Finally, the third picture shows the rare "wild" Przewalski's horse, which actually doesn't survive in the wild anymore, only through captive breeding. General N.M. Przewalski (1839-1888) was a Russian explorer and naturalist.
