Freshwater jellyfish

[MermanOliver]

During a dive today in a lake here in Germany I encountered a strange phenomenon: Freshwater jellyfish. They look really, really strange, especially since up until now I have associated jellyfish with seawater only.

Did somebody else come across them, or does someone know more about them than what is stated on Wikipedia?

The thread I made here has disapperaed??? Oh well!

This one is from Redgranite Quarry and they're out again this year. Just saw 2 last week. Just in time for the quarry clean-up! (see thread in Great Lakes Pod)

I would love to see them. =) which lakes did you guys see them in?

Yep! In Palau I believe.

There are freshwater jellies in an old quarry near here. Jellyfish in Quarry (http://www.journalnow.com/news/local/article_caaeae70-76d0-11e2-a8c3-001a4bcf6878.html)

As for Palau, Jellyfish Lake is on my bucket list!

How cool! We will have to visit Redgranite Quarry someday. It's about 3.5 hours east of us.

[Mermaid Muir]

Really? How cool! I had no idea they existed outside of the ocean!

[Mermaid Jaffa]

Ah carps!

Being in Australia sucks sometimes!

One of the local dive shops is doing a quarry clean-up this comming saturday. Would love to freak the divers. I'm planning on going to do some clean-up and try to shoot some video of the jellies. Water's kinda murky now with all the rain.

are they by any chance in water that once was connected to the ocean, and later was separated?

Although I could imagine (especially in Germany) someone put them there.
There are exotic turtles and fish put into the wild all the time by people who bought them as pets and tire of them after a while.

Nemo, not sure if your thread is still there, I just did a quite superficial search. Sorry. But your pictures are gorgeous! Way better than what I would've been able to make, even if I had my camera with me. Thanks for posting!

Caltuna, according to an article on Wikipedia they are said to be spread by migrating birds, which would explain why they appear in an abandoned quarry. I found them in Löbejün, between Magdeburg and Leipzig, but they are said to be in other lakes around there, too.

That's fascinating!
Hopefully, I'll come across some of them one day.
(although I might have overlooked them, they're quite small)

I watched other videos of them. They are pretty cute and tiny. I wonder if Australia has any...

[Capt Nemo]

Probably do! They are native to East Asia.

Don't know if anyone is still following this thread or not... but there are a number of species of freshwater jellyfish. We have some here in WI, too. I don't know if their origin traces back to marine environments or not, but if it does it has been by thousands of yrs (or more). It is amazing just how many different species of jellies are really out there. :)

Actually, the freshwater jellyfish above are a free swimming form of hydra. The hydra has two reproductive cycles and the sexual cycle involves the free swimming part. In the other cycle, the hydra just buds.
