As organisms, corals vary, at every level -- individuals, species, etc.  Such variability is the engine of evolution.

So this is not surprising.  The question is how widespread these features are.  And how persistent they are; this study seems to show that the effects disappear as conditions grow more atypical of contemporary seas.  The prospect for the future would be of less diversity, with only those taxa doing well in a much-modified ocean.

Subject: [Coral-List] Ocean acidification beneficial in short term to Corals    ?

Hello Coral listers,

Does anyone have additional information in regards the the recently
released reports showing some corals experiencing a benefit to increased
ocean acidification and temperature? This seems contrary to has been taught..


"The study showed that this species of coral (Siderastrea siderea)
exhibited a peaked or parabolic response to both warming and acidification,
that is, moderate acidification and warming actually enhanced coral
calcification, with only extreme warming and acidification negatively
impacting the corals," Ries said. "This was surprising given that most
studies have shown that corals exhibit a more negative response to even
moderate acidification."
