RE: frogspawn out of water??????? HELP RECOVERY
I'm guessing here but I think they those corals (Euphyllia) may be more tolerant of that sort of mistreatment than some other corals. The polyps surely retracted and could have been kept wet by the moisture trapped inside.
Many corals, and I don't know if these are one of them, have evolved to withstand temporarily being left high and dry during low tides in tropical lagoons. What makes this worse is that we are talking about equatorial areas with the sun beating down on them in addition to the low tide situation.
