How will the climate crisis affect one of the ocean’s fiercest predators? New research published Wednesday has examined what might happen to sharks’ highly specialized, flesh-cutting teeth.

As carbon emissions increase , the ocean is absorbing more carbon dioxide from the atmosphere, lowering pH levels and making seawater more acidic , a process that can affect many ocean species and ecosystems.

“Since ocean acidification is known to damage calcified structures like corals and shells, we wanted to investigate whether shark teeth, especially in species … that swim with their mouths open to ventilate their gills and have constant seawater exposure, might also be vulnerable,” said Maximilian Baum, a biologist at Heinrich Heine University in Düsseldorf, Germany, and lead author of the stu
