Anemone? ID 5/25/13
Hello,
<Derek>
I was wondering if you would be able to help identify the anemone in the attached picture.
<Mmm, not just from this one pic, no>
I got it, along with some other coral in a trade and while he called it a carpet anemone I failed to find any pictures that matched to get an exact ID. It's doubled in size since I got it, and seems to be doing well. Not sure if it helps, but the tentacles are not sticky so I've not been able to feed it like I do with my BTA.
Thanks in advance.
Derek
<Can you scoot the substrate away from the pedicle and get a close, flash pic? Bob Fenner>

Re: Anemone ID 5/25/13
Hi Bob,
<Hey Derek>
Hopefully this one helps, but unfortunately the way it's sitting the foot is attached to the rock and not the substrate, so I couldn't really move away much. Not sure if it's helpful, but around the foot and when disturbed it has some fine purple thread like tentacles that come out (see bottom left in the pic).
<Acontian fibers perhaps>
When I originally put it into the tank, and it was fully closed, the foot looked similar. There were so many "threads" that I thought it had been damaged when it was removed from the original tank.
Thanks for the help. If this isn't good I'll catch it after dark when it closes up more, and then see if I can't get a better picture. The camera is having a hard time focusing, so I may have to get my wife (the photographer) to put the camera in manual mode and get a better one. I'm a auto-focus point and shoot photographer :)
Thanks,
Derek
<The strange clustering of the base of tentacles... that so many are bifurcated is throwing me. I don't know what this is, but will look through my references. BobF>

Re: Anemone ID 5/25/13
Hi Bob,
<Hey Alex>
I think the "anemone" in question might be a Corallimorpharian like Rhodactis or similar, not a true anemone.
<I do agree with you>
Cheers, Alex

Hi all! Quick question about a live rock hitchhiker... 4/10/13
First off, LOVE your site! It helped me ID quite a few hitchhikers like Neothonidium magnum and a shy glass Cerianthid. Google helped, but you guys were the linchpin! Thank you so much!
<Welcome!>
Ok, my question. Recently we got some live rock from Florida and it came with the usual critters (unfortunately a few Aiptasia, but whatevs), but there's one thing that I can't seem to identify. It looks like a calcium carbonate free coral, about the size of a quarter, fleshy, and moves under current, but the "dusty" quality of it and the thick, cup-like shape of it is kinda throwing me. Also, from the underside it has a slightly orange/pink hue. Zoanthid? Anemone?
<Mmm, well, the size and arrangement of tentacles discounts the Zoanthid and Anemone possibilities... I think this may be a light-starved Corallimorpharian... possibly a Ricordea. Have sent this on to LynnZ for her input>
Also, sorry about the size of the pics. I'm doing this right before I leave for work!
Thanks again for the awesome site!
Eric
<Thank you for being part of it, sharing. Bob Fenner>

Mmm, maybe, but... what is this on the right? A Foram? Lynn... help!

Hi all! Quick question about a live rock hitchhiker...
Lynn, any idea/s? B
<Yep, I'm guessing it's a Corallimorph of some sort, possibly a bleached Discosoma carlgreni (aka the "Forked-Tentacle Corallimorph") or Discosoma neglecta (aka the Caribbean Umbrella Mushroom)? I'm leaning towards D.
carlgreni because of the branched appearance on the "ribs".
<<Ahh, yes!>>
Here's a link showing both spp.:

Strange marine thing 12/23/12
Hi, Can you identify this please. It appeared one day in my marine tank.
I'm not sure if it is eating the purple mushroom type coral or the coral is doing something odd. The marine tank set up in its youngest elements is 6 months, I got a larger tank, Angela Hoynes so some of the live rock came from that tank and some is new.
<Oh Lynn! >

Strange marine thing    12/23/12
Oh Lynn!
<Oh, brother! Heheee - I saw this query yesterday and couldn't hit the "back" button fast enough! It almost looks like a curled up Corallimorph of some sort but...?? I'll go ahead and send a reply asap.
<<Oh yeah! At first glance, I'm... Uhh, is this a Prosobranch of some sort?
Mmm, don't see any sensory structures... Umm, a Cnidarian/coelenterate it sort of reminds me of... something in my distal, way back past? Oh, best send along to Lynn!>
How was the trip?
<Ahh, very nice. Good weather for the most part, good folks, friends to share all with... Interesting diving, though too much BGA and reef damage to suit me>
I bet you got some great photos to post, huh?
<A few; am thinking to post some by group on FB, Facebook... do you look at them there?>
Can't wait to see some neat critter shots in the dailies!
<Oh yes... am a couple years ahead on the marine side currently... but you can look/see what the archived/newer ones will be... Again, mostly only organisms that are new to the site, or something to add to the current depictions there of worth>
Take care,

Strange Marine Thing: Possible Corallimorph – 12/23/12
Hi,
<Hello there, Lynn here today.>
Can you identify this please.
<I’ll sure try, but no promises on this one! My first impression is that it looks like some sort of Corallimorph that’s reacting to the other nearby Corallimorphs by curling away from contact.>
It appeared one day in my marine tank.
<Interesting>
I'm not sure if it is eating the purple mushroom type coral or the coral is doing something odd.
<I think it’s trying to avoid contact. What doesn’t make sense to me is why one would suddenly appear in the middle of those that are incompatible? Perhaps it was dislodged/floated away from its original position and somehow ended up there? If it were me, I’d gently nudge the thing to see if it comes loose and if so, place it elsewhere. If it doesn’t, you can either leave it as and let the dominant organism(s) “win” or do whatever it takes to remove the larger specimen with the understanding that it could either die or grow back if enough is left behind. For more information regarding Corallimorphs, please see the following link (as well as associated links listed at the top): http://www.wetwebmedia.com/corallim.htm >
The marine tank set up in its youngest elements is 6 months, I got a larger tank, Angela Hoynes so some of the live rock came from that tank and some is new.
<Gotcha, thanks. If you have any other questions or problems, please let me/us know. Take care, Lynn Z>

anemone question or ID please - 11/15/2012Please help if you can.... have any idea of what these are....I have attached a crude photo.
I think baby somethings, but my strong points are not anemones. Hope attachments come through.....if not how do we send pics.
thank you so much in advance,
Grant
<Ahh, this is actually a type/species of Corallimorpharian, Mushroom.

Unidentified Anemone 11/9/12
I'm very interested in knowing what species of anemone this is. It came in a shipment from Jakarta that I received about a week ago. It's an aggressive eater (I'm feeding it Mysis shrimp) but it closes up under strong lighting. The closest thing to it that I've seen is a waratah anemone (*Actinia tenebrosa*) but I'm pretty sure that this is a different species. Any feedback would be much appreciated.
--
*Thank you, Aaron Dragseth*
<Mmm, the tentacle ends/tips aren't "right" for Actinia tenebrosa... My guess is that this is an aberrant Entacmaea. A beauty.
Bob Fenner>

Re: Unidentified Anemone 11/9/12
Thank you for your feedback. I agree that it isn't an Actinia tenebrosa but it also doesn't really look like or have the same behavior as Entacmaea quadricolor. Are there other species of Entacmaea?
<Not as far as I'm aware... but have seen E. quadricolors look like this from rough handling, shipping>
I actually received 3 of these anemones. They were all firmly attached to small pieces of substrate that they have continued to cling to even a week later. Two of the anemones
had the same foot but a completely separate set of tentacles and each had their own oral disk. They remind me of the aggregating anemones (*Anthopleura elegantissima*)
<Yowzah! I did a histological study of this... clone anemone... common off of San Diego's coast... for a marine invert. class... many years ago>
that are common in my local California tide pools. .
<D'oh! That and the giant green of the same genus. Bob Fenner>
Re: Unidentified Anemone 11/9/12
I know what you mean when you say "but have seen E. quadricolors look like this from rough handling,", I agree. The big difference on these anemones are that they seem to be very healthy. The tentacles are very sticky, in fact I would say that they are stickier than those on even the healthiest of bubble-tip anemones.
Also, the foot is more like that of the our local Anthopleura species, very leathery with an extremely strong adhesion to the substrate. An unhealthy Entacmaea would never have such a strong hold on the substrate and the foot is much softer. With that said, I currently have it listed for sale as a Crimson Mystery Anemone (Actinia sp.?)
<A good name>
What do
you think?
<I do wish I were home, w/ my reference works... Am out visiting in Europe.
Maybe a (hard) run through Daphne Fautin's "Hexacorallians of the World"
(.com), http://hercules.kgs.ku.edu/hexacoral/anemone2/index.cfm
will be productive>
LOL! It's interesting that you worked on those California Tidepool anemones, I remember my marine biology teacher daring us to stick our tongues in them and most of us did!
>"Squirt!"<
Would that even be legal today?!!
<Heeeee! BobF>
Help with anemone identification 11/9/12
Hello Bob, I thought that you would find this reply from Karen Sanamyan interesting. I'm not sure if you are familiar with her or not but she is a marine biologist at the Kamchatka branch of the Pacific Institute of Geography, she specializes in the taxonomy of Actinaria and is one of the authors of Actiniaria.com. It sounds like we have an
<I'll say! Thanks for sending this along Aaron. Wondered re the apparent empty-of-tentacles space on the face, the open mouth... BobF>
Subject: Re: Help with anemone identification 11/10/12
Hello,
Well, very interesting species.
It has capitate tentacles (small spheres on the tips of the tentacles), such tentacles usually occur in stone corals and corallimorphs, and in general are not characteristic for true anemones (Actinaria), (except Telmatactis and a few other Actinarian genera).
Further, on your photo I see that it has several some tentacles arranged radially of the disk (arrows on attached photo). This feature excludes all stone corals. Several true anemones have tentacles arranged in radial rows (e.g. Stichodactyla), but they all are very different and have no capitate tentacles. So, this is a Corallimorph species (corallimorphs are all "mushrooms", e.g. Discosoma, Rhodactis, Corynactis, Ricordea and others - you know). However, the species on your photo cannot be identified with any known Corallimorph species, I think this is undescribed (=new) species.
Best wishes
Karen Sanamyan
