Rare sighting of Tadpole Shrimp, a prehistoric creature that existed on earth for 550 million years
@stux I think this means we can put that whole "theory" of evolution aside. Or did I just miss something?

@WatchyaSamantha Why haha  Some animals are puuurfect as is and don't have to evolve 💪

We hoomans have still a looong way to go 

@WatchyaSamantha Just to make sure I understand your logic, you think that since one species showed little need to evolve, that means none of the estimated 8.7 million species on earth have ever evolved?
@N8 I am pursuing a psychology degree and I just had to take biology 1110+ a lab, so please forgive my sarcasm
@WatchyaSamantha @stux Did you just miss something? Maybe all of biology, geology and paleontology!
@WatchyaSamantha @stux
No. Not finding your truck keys for awhile doesn't disprove the Theory of Transportation.
We still have apes, alligators and horseshoe crabs too.
@stux
How cute - and simultaneously amazing? Where is this?
@lolonurse Looks like Utah, maybe around Arches National park? Saw similar ponds, much smaller and no shrimp on Slickrock outside Moab.
@ottominati
Interesting. I assumed it was salt water, and exotic. But we have exotic places here. Hmm- western US states, Alberta, Saskatchewan, & parts of Asia & S America! Cool!
👍 probably found in a few locations.
@stux That's a lot of generations 😊
@stux triops! They are so cool.
@EvolvedGuppy @stux I thought that what they were.
@stux They look like mini horseshoe crabs. Do you know where these were filmed?
@stux the background is gorgeous too!
@stux the background looks like UT or AZ am I close?
@stux and what a stunning environment to live in. No evolution needed.
@stux ❤️❤️❤️❤️❤️
@stux
I suspect if he tells where this was filmed, you’ll get a hundred good ole boys with nets and whatnot traipsing all over their tiny fragile environment, just to catch them and nail them to the wall of their garage, between their 1978 Texas license plates and a stack of old paint cans.
Then they will truly be #Extinct . So, no do not tell us where they are.
@LizaBrings @stux Triops only live for about a month, they specialize in shallow temporary pools that don't last long and their eggs usually only hatch after the pond has dried up and been filled again, and they can lay dormant for over a decade. Fishing up a pool of them probably wouldn't have major negative effects on the population, in this case (also, they're tiny, the big ones are only a couple inches long, so not exactly the most impressive prize anyway).
@TatiMarrone @stux
Well I guess you don’t get to thrive for 500 million years without having a few tricks up your shell! 👏🏻👏🏻👏🏻
@stux that animal lives 2-4 weeks, has been reproducing for hundreds of millions of years, and as far as evolution is concerned, perfect for its environment with zero need to evolve.
@stux Incredible little thing.
@stux I'll bet they won't survive humans unfortunately.
@SocialistStan @stux don't underestimate them. They already survived a lot of catastrophes.
@stux I used to have some as pets, very cute!
@stux did anyone else think of slugcat?
@stux Extraordinary creatures in an extraordinary landscape. Thanks for posting.
@stux Apparently the credit should be to Adar Leibovitch.

@stux Science nitpick: These are not prehistoric creatures. They are very much modern animals.

And no, they are not the same animals as those that lived millions of years ago. These animals evolved and changed. It's just that the outward look of this particular specimen evolved to be similar to what we think some prehistoric animals might have looked like.

TL;DR: There are no prehistoric creatures alive today. If they are alive, they aren't prehistoric.

@attilakinali @stux true but the fossils we have of these guys from way back in the Triassic are considered to be the same genus as the modern ones. I don't know if that's a matter of them needing more study (there seems to be little work regarding them and most of it focuses on their life cycle and figuring out what the eggs can and can't survive), but if it's correct a single genus making it that long with minimal change is impressive.

@TatiMarrone @stux That's what I'm saying: there isn't minimal change. There has been minimal change in its outward appearance. The animal itself is for sure very different.

We should note here that form and outward appearance does not say much beside that it's evolved to fit a certain niche. And plenty of unrelated animals have evolved to look very similar because it ended up being advantageous for a class of niches. Most notable here is carcinisation: https://en.wikipedia.org/wiki/Carcinisation

@stux they look good for their age… 😁
@stux amazing video quality for prehistoric!
@stux They look like giant triops like the ones we grew at the library a few years ago
@stux thank you! Learned about these but had not seen video. This is magical!
@stux looks like a face hugger
@stux They are looking like the Triops out of the YPS Comics. Two Friends of me has bred them a year ago.
@stux they look like little horseshoe crabs
@stux Woww! Where on planet earth is this filmed? (if it even is planet earth)
@stux i want to hold one like a guinea pig
@stux They're not incredibly rare as you think actually a lot of people have had these as pets without knowing it.
Notostraca Triopsidae or Triops are known by the common name Tadpole shrimp but even better known as Sea Monkeys. This is what they look like when they're allowed to continuously grow. Problem is the places they would best survive, Stagnant pools with lots of food, dry up. Or if they're too big to dry up, they're overpopulated with other fish who would prevent them from getting too large.
IIRC they are technically immortal like lobsters and will only die when they can no longer shed their shells (or killed by external means).
