Ocean acidification altering the architecture of California mussel shells

Jan. 5 (UPI) -- California mussels aren't built like they used to be. According to new research, increasing ocean acidification is altering the structural makeup of mussel shells along the West Coast.Traditionally, long, cylindrical calcite crystals for neat and predictable rows in the shells of California mussels, Mytilus californianus. But as detailed in a new study, published in the journal Global Change Biology, that geometric consistency is no more."What we've seen in more recent shells is that the crystals are small and disoriented," study leader Sophie McCoy, assistant professor of biological science at Florida State University, said in a news release. "These are significant changes in how these animals produce their shells that can be tied to a shifting ocean chemistry."Scientists ...
