….”Galloway and Schram plan to study over the next two years if Dungeness crabs are even affected by increasing carbon dioxide levels in the ocean that result in an increase in acidity, or pH, in that water.
Research on bivalves — hard-shelled mollusks, such as clams, oysters and mussels — has shown that increased acidity in the water makes it difficult to build shells. But very little research has been conducted on crabs, whose shells aren’t as hard.
