Zenia help please.....

[Gary Majchrzak]

That looks like the same type of Xenia I refer to as "Red Sea", Guy- much shorter and paler than 'elongata' and it seems to prefer really intense lighting more so than elongata. It's also likely to pulse much faster than elongata, IME.
There are 3 or 4 types of pulsing Xenia that are common around the URS and 'elongata' and "Red Sea" (umbellata?) are two of them.
Dr. Klier has a silver tip type of pulsing Xenia he props and a few folks around here have Heteroxenia. There is also a type of Xenia (commonly) called "Pom Pom"- but in some cases people are simply using a different name for what I believe is X. umbellata . There is also some Sansibia (true blue Xenia) floating around here locally.
(Perhaps some other types that I'm unaware of, as well... drbronx has a lot of Xeniids.)
Here's (what I believe to be) "umbellata" up top and "elongata" down lower.

I'll get that for you Gary, but just as a reference for now, 21 species of Xenias come out of the Red Sea alone Be back w/ the sources.

If you scroll down, you'll see Xenia cf. elongata, Red Sea.

The ones you call Elongata Gary are the ones I've always believed were to be called Elongatas. However, they are different from the ones pictured in Wet Web Media. Pehaps there's a Red Sea Elongata and a Indo Elongata commonly called the Thin Bar xenia since it's very thin and brown.

Sounds like Drbronx and I should chat. There's a pic posted above w/ 9 different types of xenias.

What also appears to be Elongatas on the top left area of the image are not. They're the goldbacks with a metallic gold coloring on the back of each polyp like this.

Oh yeah, none of these are Red Sea Umbellatas

Thanks for getting back, XM.
Common names aside- species status is still up in the air regarding many types of Xenia so I don't know if we can debate their naturally occuring range.
There appears to be Xenia endemic to the Red Sea (Xenia macrospiculata), but even if we're talking about a wide ranging Indo-Pacific Xeniid I don't doubt Guy's observations for a moment.

 

[XeniaMania]

I'm not doubting him either. I've noticed there are articles about Xenia Macrospiculata being the dominant xenia in the Red Sea. Where they come from is still up in the air as you say, but according to WWM, they put the Elongatas as Red Sea which is why I asked that question, it wasn't a question of doubt..

I'm currently in pursuit of trying to get as many scientific names attached to my xenias as possible. Bob Fenner has pointed me to local university libraries, but owning my own company, it's not always easy spending hours in the library.

It's not always easy even if you work for someone else!
You have some nice Xenia.

I have a Xenid I've always just called Heteroxenia. I would love it if you could help me positively ID it. Can that be done with a pic or do you need a sample? Willing to give it a try?

 

[XeniaMania]

Guy, do you mean scientific name the guy or to just confirm if it's a heteroxenia or not? These are the scientific names I got for heteros:
Ã"šÃ‚· Heteroxenia coheni
Ã"šÃ‚· Heteroxenia cf. elizabethae
Ã"šÃ‚· Heteroxenia fuscescens (Ehrenberg) (1,2)
Ã"šÃ‚· Heteroxenia ghardaqensis (Klunzinger) (1)
I'll be more than happy to do my best with a picture, I haven't gotten good enough at this to say a sample would help me help you. But I'll be more than happy to help..

Gary, sorry, I didn't mean to make it sound like everyone else has time except me Thanks for the kind words too!

Also, since there's so much talk about Xenia Macrospiculata, would anyone happen to have a picture? It's one more xenia I can cross off my list then..:lol:

 

[Guy]

Let's see if I can get the pictures to display:

 

[XeniaMania]

Yeah that's a hetero alright, first time me seeing one like this too (you can imagine me almost drooling) :lol: The common ones I've seen are white. It should be pretty straightforward once I get a description match on this one. I'll keep you posted. Thanks for the pic.

 

[Guy]

Cool

Thank you for any help you can provide. I really appreciate the positive ID on it being a Hetero.

 

[XeniaMania]

There's 15 species that's known, with Heteroxenia cf. elizabethae excluded as a possibility already. Examining all the Indo-Pacific Xenias/Heteroxenias has left my head spinning already :lol: But I find this type of stuff challenging and entertaining.
Question: Would it be possible to get pictures of how they look like at night or when disturbed? Thanks.

 

[Guy]

Sure, I can try that.

Are the 15 described species. I have a feeling I know which one it is, but I'd like to verify further before just blurting it out.

 

[XeniaMania]

Just sharing a site w/ you Guy. Take a look.

What I'm having a hard time getting over is how this hetero resembles the Bali Xenia, cept the Bali has translucent body versus white and the polyps are a bit different.

yes yes, I know it's posted on the previous page but it's on the same page now for convinience :lol:

 

[Guy]

Nice link, thanks!
