Anthropogenic-driven accumulation of carbon dioxide in the atmosphere and projected ocean acidification have raised concerns regarding the eventual impact on coral reefs. This study demonstrates that skeleton-producing corals grown in acidified experimental conditions are able to sustain basic life functions, including reproductive ability, in a sea anemone‐like form and will resume skeleton building when reintroduced to normal modern marine conditions. These results support the existence of… 
Reproduction of an azooxanthellate coral is unaffected by ocean acidification
TLDR
It is suggested that reproductive potential may be quite tolerant to decreasing pH, with implications for ecosystem function and services in a changing ocean.
Reduced heterotrophy in the stony coral Galaxea fascicularis after life-long exposure to elevated carbon dioxide
TLDR
Unless replenished by other sources, reduced zooplankton uptake in G. fascicularis acclimatized to ocean acidification is likely to entail a shortage of vital nutrients, potentially jeopardizing their health and survival in future oceans.
Effects of Ocean Acidification on Early Life Stages of Scleractinian Corals ( Genus Acropora )
Ocean acidification is predicted to progress with increasing atmospheric carbon dioxide concentrations emitted by human activities. This may be one of the most serious threats to marine calcifying
Combined responses of primary coral polyps and their algal endosymbionts to decreasing seawater pH
TLDR
The previously unseen intricate net of interacting mechanisms that regulate the performance of these organisms in response to OA are disclosed, finding that decreased pH conditions stimulate photosynthesis and endosymbiont growth, and gene expression potentially linked to photosynthates translocation.
Octocoral Tissue Provides Protection from Declining Oceanic pH
TLDR
A protective role of the octocoral tissue against adverse pH conditions, thus maintaining them unharmed at high pCO2 is suggested, in light of the competition for space with the less resilient reef calcifiers, octocorals may have a significant advantage under greater than normal acidic conditions.
Effect of Ocean Acidification on the Coral Microbial Community
An emerging environmental stress that can impact coral reefs worldwide is ocean acidification, a result of increasing atmospheric CO2 concentration. Surface seawater pH is 0.1 units lower than
Colonies of Acropora formosa with greater survival potential have reduced calcification rates

Geochemical consequences of increased atmospheric carbon dioxide on coral reefs
A coral reef represents the net accumulation of calcium carbonate (CaCO3) produced by corals and other calcifying organisms. If calcification declines, then reef-building capacity also declines.
The Origins of Modern Corals
TLDR
In their Perspective, Stanley and Fautin suggest that lineages may have lost and reacquired skeletons repeatedly as conditions favorable to calcification waned and waxed.
Evolution of Scleractinian Corals Inferred from Molecular Systematics
TLDR
A molecular phylogenetic analysis of mitochondrial 16S ribosomal RNA showed departures from previous hypotheses of coral evolution, and fossil and molecular data suggest multiple origins of the scleractinian skeleton, and the great morphological diversity of present-day sclerACTinians may be a reflection of these multiple origins.
Oceanography: Anthropogenic carbon and ocean pH
TLDR
It is found that oceanic absorption of CO2 from fossil fuels may result in larger pH changes over the next several centuries than any inferred from the geological record of the past 300 million years.

TLDR
Complete mitochondrial genome data are presented that provide strong evidence that one clade of scleractinians is more closely related to Corallimorpharia than it is to a another cladeof scler actinians.
