The nutritional quality of fish and squid deteriorates under warm water events, research reveals - with implications for the marine environment, marine predators and fisheries capturing food for human consumption. marine snails). Several gene families involved in stress response are notably expanded in Saccostrea compared with other oysters, and likely key to this species' adaptations for improved survival higher in the intertidal zone. Coastal acidification in Australia and in many other regions around the globe is damaging oysters’ ability to grow properly – with such changes in shell growth mechanisms likely to have implications in the future.
