Wild horses are pretty rare outside of classic rock songs.

Some of the most famous ones like those on Assatea Island aren't actually wild at all.

They're the feral descendants of domesticated horses.

But the animal shown in a few recent viral TikToks may be

another matter entirely, a horse of a different color, if you will. Or more accurately,

a horse of a different species. For Scientific American Science Quickly, I'm Rachel Feldman.

Associate News editor and friend of the Pod, Alison Partial,

is here today to tell us more about these majestic beasts. Before we get into it, I have one very

important question to start us off, which is, how do you say the name of this horse?

I would love to tell you, a lot of my sources when I asked gave me different answers.

So, you know, we're going to take this with a grain of salt. It is spelled, P-R-Z-E-W-A-L-S-K-I, but it is pronounced Shavalsky or Przvalsky. A lot of people will put a P in the front, and I'm not quite sure my tongue knows how to do that.

But so we're going to go with Shavalski for now.

This is the name that Western science has given them after a Russian explorer, quote-unquote,

discovered them in the Central Asian steps, but they've long been called other names in that

part of the world, too. In Mongolia, they've long been called Taki.

And in Kazakhstan, they're called the Kirtaga or the Kerkulon.

All extremely reasonable names.
