Anything other than sponges hypersensitive to a moment of air exposure?

Yes, there is misinformation and such, we can all acknowledge that. Let us suppose just for a moment, that *some* sponges and *some* gorgonians *may be* more vulnerable to damage or death from air exposure. I realize this is an assumption, but if there have been similar experiences by people, there may be something to it.

If the hobbyist does not know if his/her specimen is one of the ones more vulnerable, would it not be prudent to treat it like it IS vulnerable? Err on the side of caution? That was all I was suggesting. Better safe than sorry.

But, as I was implying earlier, lets just say that about ALL our inhabitants then. That is surely factual. They will ALL do better with less air exposure- fish corals, inverts, you name it. That is erring on the side of caution. But, to answer the original question of "what is hypersensitive to moments of air exposure", I would say that we cant answer that question with generalizations and stereotypes. Thats my only point.

There is an apparent across the board agreement on a longer acclimation period because they are sensitive to sudden changes in oxygen. Wouldn't air exposure create a sudden change in oxygen with these animals?

Again, I respectfully disagree. I have seen starfish completely exposed at low tide, and have handle so many in air that have lived for tens of years.

I think you are confusing salinity with oxygen. They are senstivie to changes in salinity, purportedly.

Huh good question. But far as sponges go I take mine out of the water regulary for about n hour or so at a time. Because it's attached to one o my frag rocks of Zoas. But my sponge won't die so I think he forgot he wasn't supposed to b out o the water.

Ok this is on the topic of y some thing die n air n others don't. Well here u go do a test take a zoa n leave one zoa n the oven not on by the way. N one in a humid environment for 3 hours. The one n the oven didn't get cooked n die it died because there was no humidity n the air n the cells broke down. The one left n a high humidity air was still alive because the cells could retain mouister. That's y u can ship come corals n a bad with little or no water n the bag. Because the bags sealed n condensation n it keeps the humidity high

I have also read that they are sensitive to changes in pH as well as specific gravity.

Anecdotal as it is, we have found better survival with slow acclimation of Echinoderms, even after shipping and being in the bag for longer than, "a trip home from the LFS."

Some species of sea star seem to be hardier than others - fewer losses overall with, say Chocolate Chip stars, than with Linckias. Sand sifting stars can lose limbs and regenerate but I haven't seen the same with Linckias.

And once I had a Red Fromia come in "disintegrating" but we acclimated it anyway... 4 of the 5 legs melted away. The remaining one got up and walked away. It had a little bit of the body disc still attached. Over the next few months it began to re-grow its legs. I gave it to a client who is a science teacher for his classroom tank.

Asterinas - you can't kill 'em.

So even within a type of organism, there can be variations in hardiness.
