Ocean Acidification Threatens Sharks' Teeth and Predatory Power

A new study suggests that increasing ocean acidity due to climate change could damage shark teeth, potentially impairing their ability to feed and affecting marine ecosystems. Experiments showed that teeth in more acidic conditions suffered twice as much damage, which could threaten shark populations unless they adapt by increasing tooth replacement or strengthening. The findings highlight the broader impact of ocean acidification on marine predators and the importance of reducing CO2 emissions.
