Ocean acidification levels predicted for 2100 (seawater pH 7.8) did not significantly affect growth, arm regeneration, biochemical composition, or righting behavior of a sea star. (Laboratory study)

Sea stars collected in Nova Scotia, Canada, grew more slowly under ocean acidification conditions, and their growth rate decreased further with a warmer temperature. In contrast, blue mussel grew more quickly with no response to temperature within the tested range. Predation of sea stars on mussels, measured as per-capita consumption ...

The common sea star (Asterias rubens) appeared to withstand the effects of reduced seawater pH, at least for short-term exposures of 15 to 27 days, with no significant changes in the strength of its tube feet or the RNA/DNA ratio of its tissues. (Laboratory study)

Near future ocean acidification increases growth rate of the lecithotrophic larvae and juveniles of the sea star Crossaster papposus

Common sunstar larvae and juveniles in ocean acidification conditions grew faster without apparent effects on survival or body structure. Unlike the larvae of some other sea star species that feed on plankton, larval common sunstars rely on nutrition provided in their egg. This difference in life history may enable some ...

Green sea urchins were able to adjust their internal pH level within 5 days after being placed in ocean acidification conditions, but sea stars (Leptasterias polaris) were not. Internal pH did not appear to be related to immune response. (Laboratory study)
