And the study is interesting too and it provides evidence that precipitation may stress sharks in a way that wasn't known before. And they don't really know what fitness impact it would really have on them. There was a study in 2019 and it looked at the effects of pH on shark skin. It's difficult. And these are specialized scale-like structures that are stuck in a shark's skin made up of, they're much the same material as the teeth. And that helps the shark with its hydrodynamic movement through the water. And in that study, the scientists found that acidic conditions also corrode these chemicals. And there was a separate 2022 study of Fort Jackson shark. And it determined that the species teeth can resist ocean acidification, in part because of the effects of rising temperature and falling pH, may cancel out in some ways. For example, heat makes the teeth more brittle while the acid makes the teeth softer. Just trying to think.
