- We are filming a new Moab Ephemeral Pool video for the Moab Area Travel Council to reveal the amazing science and nature of the Moab desert. I had the privilege of spending the day exploring and macro filming water potholes with USGS wildlife research biologist Tim Graham. Here's some quick highlights from one pool.

The living creators in this video look Very similar to the fossils of the Cambrian explosion !
They definitely do. Especially the triops.
I love desert pools. I'm currerntly trying to recreate one in a tank. I'm going to put distilled water, sand, a few twigs and leaves, let the algae develop, and put some T.longicaudatus eggs in it. Then i'll let them breed and let the pool dry, add new water, and repeat the cycle for as long as I can
Is that rainwater trapped in a hole? What about evaporation? Do these creatures live in other places, such as rivers?
Yes, this is rainwater, and the pool only last a week or two. The eggs of these creatures can survive prolonged periods of heat, dryness and freezing, even in the desert. Fairy shrimp eggs have been taken up on the space shuttle, exposed to the -400° of space, brought back to earth had water and they hatched.
@@finleyholiday Thanks for the info! This is probably how life starts on planets, maybe critters like this are lying dormant on Mars, waiting for water to return.
@@AmazingChinaToday I think the movie Alien is patterned after some of these creatures ; )
I love this! I've been fascinated by micro life in the pools on Smith's mesa near Zion Nat. park. I've tried photographing the animals in them but the videos you have here are a lot better than mine. Can I ask what gear was used to get these videos?
Using a Sony a6600 with a Laowa, 24 mm macro probe lens. The lens and patience is the key!
@@finleyholiday well, I just added another thing to my must have list. Lol, that list never seems to run out of things.
What is the animal shown at the very beginning of the video, and at the very end? Doesn't look like a water boatman.
That is a Triops (short for its Latin name) so named because it actually has three eyes. If you look closely at the opening scene, you can see the faint third eye in the middle at the top of its head. It is a light sensing organ. Also known as a tadpole shrimp. It is a crustacean.
