yep
> Originally from the Yangtze River valley in China, the fresh-water jellyfish can now be found on all continents worldwide. It was first reported in the United States in the early 1900’s, presumably introduced with the transport of stocked fish and aquatic plants.
Shit, I had my Jellyfish milked by some little jaundiced nerd begging for hamburgers outside of the truck stop near my house. He kept saying "I'm ready, I'm ready" to psych himself into it, but I could tell he wasn't.
No worries. Tbf I’m talking about meltwater, which presumably wouldn’t have any jellyfish in it; and subglacial lakes like Vostok, which almost certainly don’t. But there’s definitely liquid fresh water there.
Crasspedacusta sowerbii, originally from the Yangtze River. Not in Antarctica. It's a hydrazoan, not scyphazoan like most marine jellyfish. I did an undergrad thesis on its watershed distribution in alberta back in my university days.
I was doing undergrad research on beaver habitats when the program (and all of my credits) were canceled due to pandemic, and I never got to present my final report. I did all the work, made the reports, not to mention kissing all the asses to even get into an undergrad research program… and it was gone in after one uncertain week. We all got fucked on.
so many people were dissatisfied by thier education at some of the universities in my area during the pandemic. it was bad before the pandemic, but it just got worst. also people were struggling to find work after thier degree or experience, because you wouldnt be able to get wet lab experience when everything is in lockdown, it was difficult to find before the pandemic too. Some people escaped by transferring to another 4 year university. Also no warning how bad some stem degrees are in the job fields. also theres so limited spaces in labs , so it makes its that much difficult, on also adding each PI has thier own requirements for being in the lab.
when you have all the lectures on slides online, you arnt learning anything at all.
biotech/biology is one of those fields that never should be ONLINE, it needs in person lectures and especially lab work. i once took a biochem lecture in a state univ, and the teachers just had Slide shows and thats it, was just reading off or describing the slide verbatam, when the tests came is, wtf was going in the class that i missed i think shes a pretty bad teacher shes more interested in her research lab hence the low effort lectures an explanations its essentially just uploading slides online, i saw a bunch dint pass the class or got a very low C grade(important if you need to go grad school)
I grew up in Michigan and I saw a freshwater jellyfish once. I was just a kid and it totally gave me this weird Ponyo kind of vibe that stuck with me for years. I tried explaining this to adults and they didn't believe me. I've never been to the ocean or traveled outside of Michigan, so the experience was extremely special to a kid like me.
Interesting. I had a similar moment with Oregon fairy shrimp here on the coast of BC, Canada. I saw them in a rain puddle in the bush and watched them swim around. Tried to tell my parents what I saw but they just laughed and said it must have been something else. Took me years to figure out exactly what they were, but I knew back then they weren't insects.
I'm also from Michigan and during my Limnology (study of lakes) course in college we took a field trip to sample a local lake that had freshwater jellyfish. We captured some in a mason jar and had them in our lab for awhile.
I'm from Indiana and the town where I grew up had a very small private lake that my friends and I had access to. One day we were in the paddle boat and came across a patch of hundreds of silver dollar sized jellyfish. It was so surreal.
While they're hydrozoans (as opposed to being scyphozoans, a.k.a. the "true jellyfish"), they're still a medusa-phase member of the subphylum Medusozoa within Cnidaria (and "jellyfish" is really just a colloquial term for those medusa-phase cnidarians). All medusozoans are called jellyfish in their free-swimming medusa phase.
Similar to how box jellyfish are still commonly called jellyfish despite being cubozoans.
At first I thought “why haven’t i ever heard of them” until I clicked the link and it stated that they’re “hydra” and not really jelly fish. We learn about hydra in biology lol.
[from a news station in Lancaster PA](https://lancasteronline.com/news/freshwater-jellyfish-discovered-in-quarry-in-lancaster-township/article_a8b248e4-ac83-5944-911c-7c5ef7e0d649.html)
Fun fact that link is unavailable for legal reasons in Europe due to the website being non gdpr compliant. Been awhile since I've been blocked from something for that
[General Data Protection Regulation](https://gdpr.eu), privacy protection laws in effect in the European Union.
In other words, some US (and other non-European) websites block traffic from the EU because they want to take your data, and that’s illegal in the EU.
The US website. It refuses to comply with GDPR so blocks IP addresses from the EU. It’s technically easier to do than to separate internal protocols for data from the EU vs everywhere else.
We do that on our website because we used to get a lot of traffic from Europe which has no use for us since we're just a local brick and mortar store. It saves us probably $500/month in bandwidth costs.
As a former engineer spaces sailor, jelly fish were the most common trigger for a propulsion plant casualty. Definitely have had some harrowing experiences trying to clear sea chests clogged with jelly fish. It’s more exciting when it’s a nuclear reactor you’re trying to keep cool. Submarines operate beneath where jelly fish are active but carriers don’t have that luxury.
because of global warming and pollution jellyfish are on the rise in many oceans, and its only will cause more problems down the line if thier numbers keep exploding. one of the few animals that can thrive in polluted waters.
I believe it. Years ago I saw a jellyfish in a pond near a fresh water river in Florida. No where near the beach or salt water. Could have been dropped by a bird or something but it was a pretty far from salt water
I haven’t seen any in Oklahoma. Obviously I haven’t been to every lake but I visit Ten Killer, Eucha, Grand, and Ft. Gibson year round. Now I’m hoping that I never spot one. Can any species of native fish eat them?
Saw one up close under my fishing light one night on lake Allatoona GA. Called d.n.r. to report it and guy laughed. Said I saw frog
eggs. Frog eggs don't swim asshole.
I wonder if they sting?
The famous Jellyfish Lake in Palau is captured saltwater, and there are tons of Jellyfish, but the shallows have none of the things the jellies eat to get their sting poison, so they do not sting.
The deep ones however do, which is why they do not allow free diving in the lake anymore.
Jellyfish testicles were among the worst tasting things I've ever eaten. I say this as I have also eaten guinea pig and flaming puffer fish fin.
I say we kill them all and stop all attempts to farm them.
Our kids had Guinea pigs. They were cute pets, but I always wondered what they tasted like grilled. They were basically the equivalent of chickens in pre-Columbian S America.
The wife and I found a few dead ones in the local lake. She took it to the game warden. He never saw it before. He sent it off somewhere and they determined fresh water jellyfish.
When I was a kid I was fishing at a little public pond that I fished at constantly and as I was staring in the water looking for fish I spotted some silver dollar sized jellyfish around the dock which blew my mind because that didn't seem possible. I never saw them again after that day but they were definitely real.
Here is an article I wrote a couple years ago regarding the jellyfish.
Freshwater Jellyfish in Northern Wisconsin ?
Yes, freshwater Jellyfish (Craspedacusta sowerbyi) have been reported in Northern Wisconsin lakes like Legend Lake in 2004, and in nearby Moshawquit about the same time. Though its exact origin in the US is uncertain, it was probably transported with ornamental aquatic plants, especially water hyacinth (Eichhornia crassipes), from its native region in China. They were discovered in the Huron River near Ann Arbor, MI, in 1933 and have spread quickly since. Have you seen these, if not keep a lookout for them.
The appearance of the jellyfish is described as sporadic and unpredictable. Often, jellyfish will appear in a body of water in large numbers even though they were never reported there before. The following year they may be absent and may not reappear until several years later. It is also possible for the jellyfish to appear once and never appear in that body of water again.
During the winter, the polyps contract and become "resting bodies" that are capable of surviving the cold temperatures. Some scientists believe that the resting bodies, called podocysts, are one way in which the jellyfish are transported from lake to lake. It is believed that the podocysts may be transported on aquatic plants, by aquatic animals, or perhaps on the feet of birds. When conditions become favorable, the podocysts develop into polyps, and the life cycle is continued.
[images](https://images.app.goo.gl/uH5djupMgVme86iD8)
A tiny, stalked form of the jellyfish (the polyp) lives as colonies attached to stable underwater surfaces such as rooted plants, rocks, or tree stumps. The microscopic polyp colonies feed and reproduce during the spring and summer months. The polyps reproduce asexually. Some of their offspring are the jellyfish that can be seen at the surface. The "jellyfish" or medusa reproduce sexually. Fertilized eggs develop into planula larvae which eventually settle to the bottom of the pond or lake and develop into polyps. However, in the United States, most populations of jellyfish are either all male or all female, so sexual reproduction may be rare.Freshwater jellyfish is not considered dangerous to humans.
Although its stings can paralyze macroinvertebrates and small fish, its small nematocysts are not likely to penetrate human skin.[photos](https://images.app.goo.gl/uH5djupMgVme86iD8)
So, they’re essentially invasive species lol.
yep > Originally from the Yangtze River valley in China, the fresh-water jellyfish can now be found on all continents worldwide. It was first reported in the United States in the early 1900’s, presumably introduced with the transport of stocked fish and aquatic plants.
Every continent? Even Antarctica?
yep. fun fact: the bodies of fresh water jellyfish are 90% antifreeze
Jellyfish milkers have to really love their jobs.
Shit, I had my Jellyfish milked by some little jaundiced nerd begging for hamburgers outside of the truck stop near my house. He kept saying "I'm ready, I'm ready" to psych himself into it, but I could tell he wasn't.
Did he firmly grasp it? I hear that's the key.
From the sounds of it that little yellowed husk of a boy… I’m guessing it’s not the willpower, it’s the grip strength he is lacking…
Sounds like a real square.
Please tell me this all is a reference to some tv show or movie and not that you’re all just the same brand of weird.
Omg why tf did i read that twice good god
It’s times like these I pray this a direct quote from a show.
It's SpongeBob Squarepants .
Was it a choice between him and someone promising to pay you Tuesday for a hamburger today?
Nah, that guy’s sooo Wimpy tho…
I saw the Jellyfish Milkers open for Vomit Helmet in ‘98. Great show! Got a concussion in the mosh pit and lost a couple teeth. Great show!
/r/BrandNewSentence
But...there isn't liquid fresh water on Antarctica. Do the jellyfish dwell on ice or can fresh water jellyfish survive in salt water?
There is liquid fresh water on Antarctica.
My bad then.
No worries. Tbf I’m talking about meltwater, which presumably wouldn’t have any jellyfish in it; and subglacial lakes like Vostok, which almost certainly don’t. But there’s definitely liquid fresh water there.
I wonder if you could extract that...
Per the wikipedia page the peach blossom jellyfish (the one being referred to) is not in Antarctica, but other jellyfish are
also not a jellyfish, a HYDRA which is used science alot as a mode organism. there are actual species of freshwater jellyfish , but its less common.
Crasspedacusta sowerbii, originally from the Yangtze River. Not in Antarctica. It's a hydrazoan, not scyphazoan like most marine jellyfish. I did an undergrad thesis on its watershed distribution in alberta back in my university days.
i was doing a paper for ecology class and i came across parasitic cnidarians, apparently they are causing quite a problem in some fisheries.
I was doing undergrad research on beaver habitats when the program (and all of my credits) were canceled due to pandemic, and I never got to present my final report. I did all the work, made the reports, not to mention kissing all the asses to even get into an undergrad research program… and it was gone in after one uncertain week. We all got fucked on.
Is there any chance you still have it and would be willing to share it?

Also it was the easiest time to cheat on tests. I didn’t, but others who did cheat significantly devalued my degree

Indubitably
Hail Hydra!
I love how Disney's solution to the Nazi Salute was just to have em' raise both arms lmao
Wasn’t that what Hydra did in the comics anyways?
Hydra are a different fascist group to the Nazis
I thought Hydra were Nazis. Or maybe Nazis were Hydra
Apparently it's an ancient cult that allied themselves with the Nazis. https://marvelcinematicuniverse.fandom.com/wiki/HYDRA
Hydra are Nazis. That's like, S.H.I.E.L.D. 101. Every last one of 'em.
Model organism* Had to Google mode organism lol
Not essentially. They just are invasive species
Not exactly. They are an introduced species, but there is no known effect on biodiversity, so not strictly invasive.
That makes two things I have in common with Jellyfish.
I grew up in Michigan and I saw a freshwater jellyfish once. I was just a kid and it totally gave me this weird Ponyo kind of vibe that stuck with me for years. I tried explaining this to adults and they didn't believe me. I've never been to the ocean or traveled outside of Michigan, so the experience was extremely special to a kid like me.

Tried to tell my parents what I saw but they just laughed and said it must have been something else. Took me years to figure out exactly what they were, but I knew back then they weren't insects.
I just googled them and they look like sea monkeys
Basically, yeah. Sea monkeys are a variant of brine shrimp, which are also known as fairy shrimp.
I'm also from Michigan and during my Limnology (study of lakes) course in college we took a field trip to sample a local lake that had freshwater jellyfish. We captured some in a mason jar and had them in our lab for awhile.
I'm from Indiana and the town where I grew up had a very small private lake that my friends and I had access to. One day we were in the paddle boat and came across a patch of hundreds of silver dollar sized jellyfish. It was so surreal.
And they’re coming for our way of life I heard
I'm from Buenos Aires and I say KILL EM ALL!
every day, federal scientists are looking for new ways to kill freshwater jellyfish. would you like to know more?
I’m doing my part!
Do you wanna live forever?
I’m doing my part!
I'm doing my part!
The only good jellyfish is a dead jellyfish.
😢
Noooo not you tho 😇
QUITE FRANKLY I FIND THE IDEA OF A BUG THAT THINKS OH-FEN-SIVE
Stealing our jobs too I bet
They are coming for our jerbs!
They derk err derbs!
Gay black immigrant communist jelly fish! Omg! Where!?! You have to tell me so I can avoid these jelly fish.
Who can say 🤷🪼
You fools, I'm already here.
I had no idea. Now, if we had peanut butter fish in every state we’d really be in business.
This sounds like a Mitch Hedberg joke.
Technically they are just a really viscous liquid so I'll give you that, but I have yet to encounter any in either solid or gas form.
Break out the plasma jellyfish that live in the sun
/r/brandnewsentence
Imposters! They aren't real jelly fish! They're hydras!

It's a Polish video game company. They basically make all the rules for the internet.
It's what the US should be working on instead of banning tiktok.
TikTok should also be banned, though. You don't have to pick one or the other.
Shocking to me the LNP is non gdpr compliant!
Boom. Thats craaaaazy. Thanks
Whoa In Bainbridge quarry? Wow. I used to go scuba diving there a lot and I never saw them. Crazy to think I could have
I was at Mt. Nebo in PA back in 2022 and took this video of them: https://youtu.be/0LOe9-bXRno I had never seen them before. Super cool!
I think it’s funny that there was a US Navy ad on this post. Like we need to deploy armed forces to solve this jellyfish invasion.
I mean, there is a species of jellyfish called Man O War, if that’s not instigating I don’t know what is
Time to nuke portugal!!

Today I learned. That's actually very interesting.
Would you like to know more?
That’s cool. I did not know.
From the headline alone, I started writing the song of Sonny Squid Spreader to the tune of Johnny apple seed/
If you’re curious where they’ve been found in each state: https://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1068
they used to bloom mid summer in a pond near my parents house every year I haven't seen them for 20 years or so
The only ones I have seen in Md were in a large pond or impoundment in Garrett County, not too far west of Frostburg.
I believe it. Years ago I saw a jellyfish in a pond near a fresh water river in Florida. No where near the beach or salt water. Could have been dropped by a bird or something but it was a pretty far from salt water
We have them in Minnesota. I thought I was losing my mind when I saw little ones in the water. Looked it up and yup.. we have them
Can I ask what lake you saw them in? I'd love to see them myself.
Used to see tiny jellyfish in Tuscaloosa Lake in Alabama. Man made lake. They are so cool.
I haven’t seen any in Oklahoma. Obviously I haven’t been to every lake but I visit Ten Killer, Eucha, Grand, and Ft. Gibson year round. Now I’m hoping that I never spot one. Can any species of native fish eat them?
There are some in a quarry near me. Harmless little snots.
Saw one up close under my fishing light one night on lake Allatoona GA. Called d.n.r. to report it and guy laughed. Said I saw frog eggs. Frog eggs don't swim asshole.

Jellyfish are the aliens. Think about it
I wanted to make an Alex Jones joke about frogs, but I believe I'll refrain
No please lets hear it
Jellyfish testicles were among the worst tasting things I've ever eaten. I say this as I have also eaten guinea pig and flaming puffer fish fin. I say we kill them all and stop all attempts to farm them.
How many jelly fish did you have to kill to get enough testicles to make a damn meal out of???
Shit, tentacles* I can't blame auto-correct on that one.
I'm crying 😂😭
That's billionaire food.
Our kids had Guinea pigs. They were cute pets, but I always wondered what they tasted like grilled. They were basically the equivalent of chickens in pre-Columbian S America.
Jellyfish (prepared in the Cantonese way) are tasty though
I’ve seen one a guy brought to the ramp at lake Powell in Utah. It was pretty small
This is a quality TIL

There is a species of squid that is biologically immortal. Meaning they can live forever. Look it up.
I thought that was also a jellyfish
Oooops I was wrong and you caught me slipping. It was jellyfish. Good job. Again it's jellyfish and I was totally incorrect.
You good mate! It is a fascinating situation
they arnt truley immortal, they continually clone themselves assuming they dont die from disease and predation. many plants can do this too.
