Sharks are known for their razor-sharp teeth, but a new study warns that rising ocean acidity could leave even the sea’s fiercest predators with weaker, more brittle bites. At the heart of the problem ...

Behind the shark's smile lies an unsuspected fragility: the increasing acidity of the oceans is eroding the structure of their teeth, eventually cracking, deforming, and causing them to fall out. Here ...

Shark teeth might be the next casualty in the climate change saga: A new study suggests ocean acidification could leave these apex predators with a serious dental crisis. Researchers found that as ...
