Ocean acidification alters properties of the exoskeleton in adult tanner crabs, Chionoecetes bairdi ...
Ocean acidification can affect the ability of calcifying organisms to build and maintain mineralized tissue. In decapod crustaceans, the exoskeleton is a multilayered structure composed of chitin, protein, and mineral, predominately magnesian calcite or amorphous calcium carbonate (ACC). We investig...

Ocean acidification can affect the ability of calcifying organisms to build and maintain mineralized tissue.
