2 year update: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-z7TijZsTKyw.html *There are some questions that I'm getting a lot so I'll just answer them here.* Q: _How can you 'accidentally' catch those animals?_ A: As you've noticed I collected a lot of seaweed and algae. The animals were probably hidden somewhere in that algae. I did not see them. Q: _What does it mean if they 'disappeared'?_ A: In the aquarium hobby, when people say "X has disappeared" It normally means that it was weakened or dead and got consumed by the others in the tank before the aquarist knows. That's also what happened here. Q: _Why did you not return the crab back to the ocean?_ A: The only saltwater I had was the water in the jar. That water was already polluted, which was fine for in the ecosphere but it wouldn't have been good enough to transport the crab. It would have been a trip of a few hours, too long. If I had tried to take it back it would have died. Instead, it got to live another five months. Q: _If it were in the ocean the crab would have lived a happy long life._ A: If that crab was still in the ocean, the chance of it being eaten at it's small size or dying for other reasons would have been really high. Only a very small percentage of crab babies ever make it to adulthood. If it makes you feel any better, the crab nor the starfish have consciously suffered. Starfish don't have brains and crabs aren't capable of any complex emotions other than physical pain. For all questions that concern the working of the ecosystem, like: _Where do they get air?_ or _You should do water changes_ please consult this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K0ImENkmIBo.html If you want to try this yourself but don't know how, I made a how to video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2vm8fqqJpZM.html
Coming from someone who lives on an island and is surrounded by ocean, it is SO EASY to accidentally take home creatures, and often if you live far from the ocean [foreigners traveling from place to place] it's best to just take them with you than to return them to another beach far from where you've found it, or even travel back to the same beach. The amount of stress the animal has endured + change in environment would 80% of the time kill the animal anyway. If they happen to survive, for creators like this, it's a good thing! This experiment isn't as 'cruel and harsh' like people are saying. The crab was a mere accident, and there's millions of them all over the beaches. If anything, the little dude probably enjoyed free no effort food, and no predators for the 5 months he lived there. Thank you for telling the full story! It's amazing to watch things like this. I was very interested to see what had come of the little jar.
RelentlessPedigree no it's not true at all, you're right. Just because starfish don't have brains doesn't mean they can't feel pain. They have a very complex nervous system. and as for crabs not having complex emotions, you may want to read this science.time.com/2013/01/18/do-crabs-feel-pain-maybe-and-maybe-we-should-rethink-eating-them/ they certainly can remember and avoid repeating certain instances where the suffered pain. Thats definitely more than just a reflexive action. Animals, invertebrates deserve compassion regardless. My cousins have accidently caught ocean crabs(i live on an island, and they were the same kind as that one I think) multiple times to where I had to release them, one to a wave pool, I even marked his shell as an experiment and he was still alive weeks later. They may stress, but it's better to give them a chance at surviving.
In order to grow larger, crabs need to shed their "shell". They do this by heading to dry land to cast off their skin and emerge larger. I learned this after my first pet crab died, because I did not provide it a dry space to shed its skin. Afterwords, I adjusted my habitat to have a "beach" area, and the new crabs did very well. I hope this helps understand what happened. :(
This may be true for some crabs but I doubt it applies to ALL crabs. Some of them live in very, very deep water and those ones probably never see dry land.
thinking of getting a crab and i'm curious. how did you set up the beach area? i'm assuming your new habitat wasn't in a a jar because i'm not sure how you'd make a beach in there.
@Holly Robertson there is a link in the top comment by the poster; the plants generate oxygen and release it into the water. Pretty much how our atmosphere has most of it's oxygen replenished by trees and other above water plants.
All praise jar crab for he was separated from sin by his holy jar of life yey though he died his sacrifice was so we might learn to be as he was. Without sin and inside of a jar!
@@jaggirl yea! Its because (at least for goldfish this is how it works) they release a certain type of chemical, I forgot the name, that lets them know when they start getting to big for an area, so if a goldfish were to be put in a small tank, it would grow until the chemical would (basically) tell it to stop
WARNING when doing this experiment be sure to have an air hole or the dead matter will begin to build up pressure against the glass and may explode if you have an air tight jar because dead matter will release loads of gas
I'm extremely high and was thus incredibly invested in the crab. Whenever it showed up I got so excited and felt so proud of it growing up. So sad for the thing ;(
That was the cutest little crab ever! I think he was happy- he was safe and fed and loved. ❤️❤️❤️ The issue of freedom and limited space may come up, but he was a tiny crab, not a blue whale. I don’t think they travel very far from their home base.
There are two types of worm, ones who jiggle and ones who don't. Reminds me of what Drax from Guardians of the Galaxy said: “There are two types of beings in the universe - those who dance, and those who do not.”
I suggest keeping these ecospheres in a temperature controlled environment. preferably at a lower temperate. might help quite a bit. i would also seek remove any crabs or crab nymphs to eliminate ammonia spike risks.
“Out of the depths of the earth.. 🧐🤔(er).. of the jar..!!” You gotta love it. Your videos are wonderful! Thank you for inspiring so many of us, Life In Jars! 💜😘🌎 Also, lovely Jeff Goldblum quote.
Every time I see your videos I think about how cool it would be to make really large closed ecosystems. In the order of a few cubic meters. In this case maybe simulating waves through some mechanism. Maybe have a small beach with rocks and a deeper section. Things like that. I do find these things fascinating.
How about one the Size of a stadium? Be interesting to run the experiment for decades and see how the captive life differed from their wild counterparts
@@l21n18 There were the Biosphere experiments. Those were likely a bit ambitious. Way beyond a terrarium since people tried to live in them from the start. I think experimentation with various sized closed terrariums excl. people is a good starting point. Even a stadium sized one as you suggest. Something like that could contain a drone or rover or two for an inside view and select manipulation too.
@@marioncobretti8210 that's a pretty strong idea of acid though. The acid in our stomachs still takes hours to digest things "debatable on size and natural protection is a virus would be perfectly fine but a burger gone in 4 hours" but xenomorph blood is practically Nital.
What amazes me is that after a full year, you have life still thriving inside the jar WITHOUT your feeding it. I mean, you didn't add anything to the contents and life continues to go on it's merry way.
That is an amazing video, very well done. I never knew somthing like this would work. Great job for the documentation process. That alone is a process to get lost in. Capturing a year long video is an achievement in it self. Thanks for sharing and doing this. It's fascinating!
🧐 And then, he died because the long term closed ecosystem caused a chemical imbalance in his brain, which led to Alzheimer’s and he forgot how to live. 😥
well just think about all that protein and omega 3 you most likely gotten from accidentally swallowing the sea water. so it won't hurt you except the salt water which can cause dehydration.
It makes me think of the accidental gulp of saltwater at the beach while swimming. Teaming with life! Great music and production/commentary. So enjoyable to watch life persevere.
Yeah but when they do escape, you can bet your bottom dollar that they'll televise it and classify it as reality tv even though everyone else will know it's actually all scripted....
:/ Seriously??? With all that talk about "climate change", you'd think your generation would be a little bit more wary about making another Oxygen Catastrophe. Algae and cyanobacteria are not to be trusted.
I bought an inexpensive pink childrens tank in the petshop with a mermaid theme plus some cheap coldwater plants. I filled it up with colored stones and went to a river to collect water. This was roughly 6 months ago. No light, sitting in corner in my kitchen near a window, no heater, I bought liquid oxygen which is super for a tank this size and then I let nature happen. Basically, the plants are gone, algae grew a little bit and i have small snails. Thats it so far, but I havent checked properly for tiny creatures like microbes. So lets say I only have those snails. Its perfect. I have no maintenance but still something is moving and its fascinating to see the changes in the tank. But like yours, beautiful it isnt, but its life and I like it.
The crab had entered this world but not only did he survive he thrived! Upon his death he entered the halls of Valhalla as a hero leaving his mortal shell behind as a reminder of his greatness. Nobody saw his last moments but you and I both know it most likely was valiant.
I did the same thing many years ago. I collected a couple of buckets of sea water and a couple of shells with sea lettuce growing on them. Tossed it all in an aquarium sitting out in the yard under a tree. In a week or so the tank turned a pea green and you couldn't see into it. Fast forward a couple of weeks and you could see hundreds of live barnacles on the glass straining the water. I'd add fresh water every week or two and it lasted for months until the cold weather arrived. The water stayed pea green and the barnacles were growing nicely feeding on the algae and plankton.
Watches the micro organisms crawling around on the glass. Remembers how much water gets into the various parts of my body whenever i go surfing. *Screams Internally*
i like to imagine one of these jars will eventually force a super-bacteria to evolve, and everything between us and death is this man and an air-tight lid
The good news? You don't have to worry about that possibility. The better news? The reality is that things are almost certainly infinitely weirder than that.
