And the pink algae is also sustains a population of brine shrimp, which are also pink.

And the brine shrimp plus the pink algae, you end up with these like this little community of pink things that live together.

This is also how flamingos turn pink because flamingos go to pink lakes, also like Lake Natron in Tanzania, and they eat the brine shrimp.

And as a result, they turn pink.

And so like all of these things are connected to the pink algae population.

which kind of sustains this little pink population on these bodies of water.

Yes, that's like the devil's hole.

There's a couple different pupfish, which are unique to these different pools of water in that desert area in the American Southwest.

So there's the pupfish and devil's hole, which I think are the most famous pupfish, because we've put millions of dollars into like researching and studying these pupfish in this hole in the middle of the desert.

And that makes some people mad.

Some people are like, why are we putting millions of dollars into these pupfish?

They're the only ones of their species.

I think that at one point there was like less than 20 of them alive.

And the funny thing about Devil's Hole is that the pupfish are interesting, but Devil's Hole actually has this enormous lake of water beneath it that the pupfish, the pupfish are living at like the top little speck of water, like near the surface where the sun is hitting.

Actually, that place, that hole has killed people.

People have dived down there and died as a result.

These pupfish are sharing that hole with the dead of the past, which we have never retrieved.

I do love pupfish.

I think extremophiles are really interesting.

A lot of extremophiles in these salty, acidic bodies of water from volcanic locations.
