Shell species toughen up in acidic oceans

Rising levels of ocean acidification may not be as damaging for marine life as previously thought.

Growing concerns over ocean acidification and what it will mean for species that make shells have been allayed somewhat by research that has shown some marine species actually increase their shell growth in seawater with high levels of carbon dioxide.

While, overall, ocean acidification tends to hamper shell growth, these new discoveries have proved that many species are capable of evolving to cope with the stresses of a changing environment; however slower growth rates of shells is still a major issue for many species.
