Zoa vs Paly

a paly takes up sand or other sediment into its coenchyme (the mat part)
zoas don't take up sediment,
puprle deaths are paly's
ppe's are zoas, as are most of the recent batch of wild zoas coming in which are erroneosly called palys

I tried researching into this, and even the taxonomists seemed to be pretty unsure. What I could find was a definite example of a Zoanthus and a definite example of a Palythoa, and then A LOT of grey areas of uncertainty. A lot of them would typically be called Protopalythoas...but I guess the DNA said although they grow quite different from the classic Palythoas, they are not different enough genetically to differentiate.
I had also heard mention of Zoanthus giganteus for the People Eaters, but could never find this name on any taxonomic list.
I personally now call anything with larger polyps Palys, just because they were not affected by Zoa Pox when I had it. Not very scientific, but if it isn't vulnerable to zoa pox, it isn't a zoa.

Thanks for everyone's input so far. I know have to look up Zoa Pox. I've never heard of that.
I usually go with the larger circle theory as well. These are paly's IMO:

Your thoughts?

You would be correct Kpax......I have a bunch of PDFs from James Reimer who is doing research on the subject. Basically he says that the Protopalythoa will no longer be used as it will be swallowed up by Palythoa like mentioned they are not different enough in DNA to be separate. The ones we call PE are zoanthus gigantus and one of the ways to tell them are the white scallops/stripes the extend from the edge of the oral disc down the stolen(stalk) when closed....Such as PPE,RPE,PRPE....etc....
Yeah, what twon and Azurel said 
. The deciding factor is the sand in the coenchyme. We used to call anything large but not a dense mat with mouths Proto (largely the PE's). That term is supposed to go away with more research... I liked Proto as a descriptor.

If the Palys take up sand or sedament into the mat does this mean they should be on the sandbed?? Confused.
Reef Gardener,
According to James Reimer they do not....He said in his research that they will get it through intake of sand particles and detritus in the water. We may not see it but it's floating around....When we disrupt the sand bed or when fish do it puts it into the water column.

Azurel,
Thank you that is a relief, I cant put any of my palys or zoa on the sandbed because my pistol buries them.

I don't have any pics or frags of the "classic" palys that have a large mat, but here's some of my former Protopalys:
Some I'm truely not sure of. They seem more paly like to me, and eagerly snatch up food, but I'm honestly not sure where to put them in the whole zoa/paly spectrum.
Having zoa pox was definitely a horrible experience, but also a learning experience. Thanks to all the helpful info about it here, I was able to get through it as fast as possible with daily waterchanges. I was surprised in the ones it didn't affect, and still wonder what about the small polyped, "classic" zoas makes them susceptable to it.
