🦈 Even sharks aren’t immune to an acidifying ocean

As our oceans absorb more CO₂, seawater chemistry is changing — and new research shows those changes may be weakening sharks’ most iconic feature: their teeth. When shark teeth were exposed to future-projected pH levels, scientists observed cracks, holes, and structural weakening forming faster than expected. Over time, this damage could outpace sharks’ ability to replace their teeth, affecting how these apex predators hunt, feed, and survive.

In 2025, Ocean Grants highlighted ocean acidification as a critical ocean challenge, recognizing that its impacts extend far beyond corals and shell-forming species. This research is a powerful reminder that even the ocean’s fiercest hunters are vulnerable to a changing climate — and that addressing acidification is essential to protecting healthy, balanced marine ecosystems.
