Ocean acidification threatens to disrupt interactions between organisms throughout marine ecosystems. The diversity of reef-building organisms decreases as seawater CO 2  increases along natural gradients, yet soft-bodied animals, such as sea anemones, are often resilient. We sequenced the polyA-enriched transcriptome of adult sea anemone  Anemonia viridis  and its dinoflagellate symbiont sampled along a natural CO 2  gradient in Italy to assess stress levels in these organisms. We found that about 1.4% of the anemone transcripts, but only ~0.5% of the  Symbiodinium  sp. transcripts were differentially expressed. Processes enriched at high seawater CO 2  were mainly linked to cellular stress, including significant up-regulation of protective cellular functions and deregulation of metabolic pathways. Transposable elements were differentially expressed at high seawater CO 2 , with an extreme up-regulation (> 100-fold) of the  BEL -family of long terminal repeat retrotransposons. Seawater acidified by CO 2  generated a significant stress reaction in  A .  viridis , but no bleaching was observed and  Symbiodinium  sp. appeared to be less affected. These observed changes indicate the mechanisms by which  A .  viridis  acclimate to survive chronic exposure to ocean acidification conditions. We conclude that many organisms that are common in acidified conditions may nevertheless incur costs due to hypercapnia and/or lowered carbonate saturation states.
