Anyone know what this is?

TIA

 

[veni vidi vici]

Someone classified this as Cassiopea xamachana or Upside down Jellyfish.Anyone have any experiance with these?

 

[tizzo]

I seen them in the keys... Alls I knew was not to touch them.

 

[spiderwoman]

I've only seen one in person and that one was a big one at an LFS.

Great....they are poping up all over my tank.Probably gonna have a problem with them stinging my coral and more importantly me.

Are they stuck to the rock or no? Cassiopiea are jellyfish - tend to be upside down, yes, but free floating and typically seek areas of bright light as they are photosynthetic. They also typically pulse like other jellyfish. IMO, that is not what it seems to be doing. In fact rocks are pretty dangerous for them as they are delicate.

Yes the are on rocks and they do not move.Ive looked at some photos of some Cassiopiea and i think i was misinformed on the classification of this creature.
Any ideas on what it is??

Probably would need more of a close up. It is unusual to be sure.

poke it with somthing...LOL well to see if it moves retracts etc.... and it would be cool to do.

It has a mouth in the center and seems to have a matrix type body ,ill try and get a clearer close up ,but i dont think i can with the camera i have.

 

[m0nk]

Wow, that is certainly interesting looking. Could it be some sort of mini-carpet anemone?

It looks like a worm similar to a featherduster. I have a wormrock that has about 25 worms living in it that look very similar to what you posted. They come in all colors - blue, whit, pink, red, green, etc... I had noticed several others around the tank that I had no idea what they were before I got the wormrock.

Could it be an echinoderm of some sort? It looks sort of sand-dollarish.

 

[coral keeper]

Maybe its some kind of mushroom coral?

 

[tizzo]

Did you do a google search on that upside down jellyfish?? Cause that's exactly what it looks like to me... As Ophi mentioned, DOES it "pulse"

+1 and apparently the babies do like to hang in LR.

 

[ophiura]

Wow that's pretty cool then!! IMO at least!! The other thing I was thinking was some sort of colonial tunicate, but not if they are popping up a lot.

 

[coral keeper]

WOW!! Thats very cool!!! DON'T kill them! start up a new tank for them?

Or give them to me!

I kind of agree it does look a little like a sand dollar, but Idk, Cool though.
