It is suggested that, under ocean acidification, maintained pHi enables calcification to proceed despite decreased pHe, however, this probably causes enhanced costs.
What meta-analysis can tell us about vulnerability of marine biodiversity to ocean acidification?
Long-term and trans-life-cycle effects of exposure to ocean acidification in the green sea urchin Strongylocentrotus droebachiensis
The results support the contention that adult sea urchins can acclimate to moderately elevated pCO2 in a matter of a few months and that carry-over effects can exacerbate the negative impact of ocean acidification on larvae and juveniles.

Sea urchin larvae appeared to be highly plastic when exposed to decreased pH until a physiological tipping point at pHT = 7.0, however, this plasticity was associated with direct (increased mortality) and indirect (decreased growth) consequences for fitness.
Ocean acidification and temperature rise: effects on calcification during early development of the cuttlefish Sepia officinalis
The growth of both embryos and juveniles was unaffected by pH, whereas 45Ca incorporation in cuttlebone increased significantly with decreasing pH at both temperatures, suggesting the phenomenon of hypercalcification is limited to only a number of animals but does not guarantee functional performance and calls for better mechanistic understanding of calcification processes.

Empirical data on organisms’ thermal performance curves, such as the one presented in this study for L. pertusa, will be useful to implement predictive models on the responses of species and populations to climate change.
Ocean acidification increases larval swimming speed and has limited effects on spawning and settlement of a robust fouling bryozoan, Bugula neritina.

How the application of transcriptomics and quantitative genetics approaches across diverse species can enrich the authors' understanding of the biological impacts of climate change is discussed.
