Acropora and water motion

oh man, these pics are simply amazing !

look at that purple !!! what camera are you using that can capture such briliant colors !!

the only sure names would be red SPS for first pic and purple SPS for second one, after that, we are all just guessing ...

sooooooo where is this SPS mine located at ? lol been planning a "reef seeing" trip for years now.
 
oh no wonder the colors are so vivid !

would LOVE to see more of your work :) if you are not going to tell us where it is, you should take us on a cyber tour instead with pics :) haha

thanks
 
As a fellow Texan, where the heck are you snagging these pics? Somewhere relatively local? :)

Great shots BTW!
 
The fact is none of us can tell which species of Acropora those might be because none of us have a specimen in front of us. Trying to pin down species based on growth form is a fool's errand. Growth form is mainly a function of water movement: species X grown in one environment can look more like species Y if grown in another. The opposite is also true. This is part of the reason the concept of speciation in coral taxonomy is malleable. The other reason we cannot identify which species these are is that in coral taxonomy, species are not always described as discrete units, as per Veron's discussion of reticulate evolution.


Going to have to disagree with you again. You may not be able to get EXACT species, but some are distinct enough you can get a general idea of what they are or aren't.. A simplex will never look like tort.

Come on man ! all you are basing your posts on is a pic of the mother colony, from the top, under ALOT of water ripples ...

what is the point of this ? we dont even know the goegraphical location of this ! you dont have pics of other angles, you REALLY can not judge or call anyone wrong or right based on the info we have, unless u have seen that colony in person ... other than that, alot of corals that are nown to NOT table, do Table in my tank, does it mean they changed their genes ? No ...


to me it seems like ure just arguing for no reason.

Oh come on Allmost, you aren't being very fair here. I'm not arguing for no reason, I'm not even arguing (prior to this post). We are having a conversation and I happen to disagree. It really isn't that hard to get a "general" Id of most corals. It just takes a little common sense and some deduction.

While I agree I can't tell you the EXACT species with 100% certainty. It's not that hard to get a general idea of what species it may be, or better yet what it isn't. Which is all I have done. I listed 2 possible species, and stated what it generally is, and then stated there is no way that it is 2 other species that were only suggested based on the posters perception of what the photographer had posted in the past, not based on any reference or attempt to actually id the coral.



So lets take emotion out of this and look at the facts.

The center of the picture is perfectly clear. What we see in the picture is a large tabling acropora, upper reef, dense uniform growth, tightly packed corralites with a cupping U shape to them. While the colour of the coral is most like redish/brown that may not help us in pinning down a species it does help us in ruling out a number of species.

What more do you need? If look at all the coral taxonomy books all images are of corals in the wild, so clearly this is the best reference for matching them up (a picture of a species in the wild) vs a captive grown picture. That is outside of having the coral in hand and a micrometer.

Based on location in the ocean (depth), and growth formation we can rule out any Stags, or deep water species. Based on general growth shape we can rule out a number of specific species that tend to grow in isolated colonies, and not "table" out. We can also rule out any "pure plating, or encrusting" species due to it's combination of tabling and branching.

While we don't know the location of the coral, we can deduce by OP's posts (or simply ask him) that the picture was taken probably somewhere in the middle east/gulf, or maybe the Philippines.

So with that said, dig into http://sdmas.com/corals
Look for species that Fit the above characteristics and I bet you can narrow it down to about 5 species. From there if we get location I wouldn't be surprised if you can narrow it down to 2-3 species.

It's really not that hard, it's just a little time consuming but after a while you start to notice patterns that make for easier association and recognition.
 
now that is some good investigation !

I was just trying to say there is almost no way we can be 100% sure :)

Oh I Agree. I have corals in my tank I can't ID. It's easier to say what something isn't then what it is :)

Sir I can assure you that "chicken", is not a cat. However I can not at this time conclude that it isn't a duck.
 
so what country did you take this shot or was it at the LFS ? why so secretive where you in an illegal area (area 51 of corals site)?
 
I've seen posts from galleon of other pics from Solomon Islands, hmmmmm.... :)


Solomon Islands?! I've been bamboozled he clearly stated it was some where you wouldn't want to vacation.. Who wouldn't want to go to SI! I assumed being from TX, and by his posting mannerisms maybe military which means he could have been stationed in either the Philippines or the Middle east. hmph.. SI "check out these pics from Hawaii.. nope nobody would ever want to vacation there." hmph
