Studies are showing that the rising acidity of our oceans is causing changes in certain fish characteristics. For example, a recent study showed that clownfish (who rely on smell when searching for a home) lost some of their sense of smell when they grew and developed in waters that had high acidity levels. This study has the overall implications that the falling pH of our oceans may give fish a biologically harder chance of survival. The change in sensory perception was only applied to clownfish in this study, and has yet to be studied with other fish.
