Why are these guys so fucking tough? What kind of conditioning took place so they evolved to handle such extreme conditions?
I mean.. No animal would ever have the need to survive in the vacuum of space (when dehydrated), the ability to handle colossal amounts of radiation, crushing amounts of pressure, the list goes on. Let alone that it survived every major extinction. Do they even come from Earth? The more I read about it, the more it appears to be the most successful organism that has ever lived and will ever live.
It's in the gif title. It's colloquially known as the water bear and it's the hardest to kill organism in the world.
It can just go "fuck this" and sit dormant for periods of time usually preserved for seeds lost in glaciers.
it's just because of the stuff they're made out of. Their organs aren't very articulate and so when they're smashed, nothing really moves out of place and the whole thing stays functional.
I mean look at his tiny hands that's one solid piece of hard tissue, you can't break it's finger bone and render the whole hand useless to pain.
I wouldn't deem them over all "successful" Successful at having hard to demolish moving parts, sure, but what can those moving parts do? Can it build a nest? What about a machine?
it's in the fucking file name you cock shit dick drilling fucking newfag fuck you
they are among the few multicellular organisms that can dry themselves out
water is a good solution for chemical reactions to take place in but it can be very damaging to tissues and proteins when frozen or very hot, however it is easily replaceable
I guess it depends on personal definition of successful like >>7778085 said.
If we're talking evolution, I believe it might be the most successful organism because it just doesn't seem like it can be virtually wiped out. It's obviously going to outlive us like it outlived (almost?) everything else. I have no doubts about that.
They can do much more than that. They have a complete digestive and respiratory system. They can survive for years without eating anything.
And we're talking about a creature with the size of 1/6 of a sand grain
>It can survive 6 times the pressure water would produce at the bottom of the Mariana trench. Your foot isn't going to do shit.
Tardigrade mass: probably a few nanograms
Mass of average human: 70000grams
70000/1e-9 = 7E+13
yeah I doubt it can survive getting stepped on by something 70 trillion times its own mass.
They are one of the few organisms that survived more than one near total annihilation of the entire ecosystems that appeared prior to the current phase of Earth. I don't mean they survived the meteor that killed the dinos, I mean they survived every epoch that reset Earth to near-zero life prior to the stuff that crawled out of the ooze in this phase.
tl;dr Life on Earth start from scratch more than once. These are just from the previous phase.
No, the weight is distributed over the entire Tardigrade and only the surface it touches on the sole of the shoe. If the sole was made of something that doesn't bend, the Tardigrade will take all that force directly.

>THEY HAVE 17.5% FOREIN DNA
>COMES FROM SPACE
ARE THE JEWS TARDIGRADES
ANYWAY GOING BACK TO /POL/ TOO
>short reproductive times
>little nutrients needed for survival
>found all over the earth
The vacuum thing I have no idea but they've found that some bacteria can survive in space.
I... I don't understand what the point of these existing is.. if they can go so long without eating.. what exactly do they do in the mean time? Breed? With so little food needed can they not breed infinitely faster and thus evolve much much faster than anything else on earth?
w-will they ever get bigger and become the dominant species on earth? like, some sort of nine legged bear-seal?
I used to work in 16 inch high ashida geta about 8 hours a day. They were quite fine. Getting off them was a trip though, messes with your head being 16 inches higher than everyone for 8 hours a day then suddenly come down to earth.
My boss was really short and when she wore them she didn't want to give them back. lol
these are the little guys that repair and heal the earth after the dominant species destroys the world. It will be their 6th repair job. they are practically experts.
water pressure is uniform, from all directions. Being stepped upon is bidirectional, meaning he'd get pancaked.
Any rock will be fine at the bottom of Marianna, but you can easily pulverize them with a hydraulic press.
Pls learn to logic
>durr everything is relative hurr
huh? you think the center of the sun at 27M F° is extremely hot? well, I can think of at least three temperatures that are higher! like, uh, 30M F° or 50! Yeah dude! you a pussy, you don't know what extreme is! DUURRRR
>implying humans aren't the actual masterrace
>implying we aren't the fucking tyrannosaurus Rex of our era
fuck off you self hating Übermensch.
